3/18/2015Webcast: Controlling the Formation of Nitrosamines During Water Treatment

Nitrosamines are an emerging class of disinfection by-products (DBPs) of health and regulatory concern. The U.S. Environmental Protection Agency (EPA) is considering regulating nitrosamines as part of the six-year review of the Stage 2 DBP Rule. Precursors for nitrosamines include treated wastewater discharges in the watershed and certain polymers (polyDADMAC, polyamine) used as coagulant aids. Nitrosamines are preferentially formed by chloramines. Jointly funded by the Water Research Foundation and the EPA, the objective of project #4370​ was to develop improved strategies for minimizing nitrosamine formation during drinking water treatment and to develop treatment guidance for utilities. This Webcast focused on the following areas of research: (1) polymer management and removing nitrosamine precursors with powdered or granular activate carbon, (2) pretreatment strategies (with chlorine, ozone, and UV irradiation) for the destruction/transformation of nitrosamine precursors, and (3) case studies on nitrosamine formation and control at full-scale drinking water treatment plants. The final report for this project is now available on the website.
2/26/2015Webcast: Institutional Issues for One Water Management
The term, “One Water,” recognizes that water from all sources must be managed holistically and cooperatively to meet social, economic, and environmental needs. As utilities transition to a One Water approach, they may encounter institutional issues related to planning and collaboration, legislation and regulations, economics and finance, culture and capacity, and citizen and stakeholder engagement. Jointly funded by the Water Research Foundation, Water Environment Research Foundation, and Water Research Australia, project #4487​ presents a framework for overcoming these institutional issues and provides case studies to show how utilities have implemented a One Water approach. This Webcast will present the findings from the report and case studies from Clean Water Services in Oregon, and the San Francisco Public Utilities Commission.
1/27/2015Webcast: Reservoir Management

Webcast and Project Synopsis: WRF Project #4222, “Water Supply Reservoir Management Strategies,” assessed the use of rapid monitoring methods, modeling tools, and oxygenation and circulation techniques for water supply management. Ninety organizations (nearly all of them utilities) and 18 vendors participated in the research, and over 150 case histories were documented in the following three separate reports, each of which were discussed in this Webcast.

  • 4222a Water Quality Modeling to Aid Water Supply Reservoir Management (2013)
  • 4222b Rapid Water Quality Monitoring to Aid Water Supply Reservoir Management (2014)
  • 4222c Oxygenation and Circulation Techniques to Aid Water Supply Reservoir Management (soon to be published​​)
12/9/2014Foundation Knowledge Webcast: Cost-Effective Safety Decisions in Water Facility Design
As drinking water facilities are replaced or upgraded, there is an excellent opportunity to reduce workplace hazards and substantially lower ongoing costs of operating safely. Currently there are few, if any, tools with which to forecast these costs and to compare the costs for alternative facility designs. To the extent that ongoing costs can be identified, quantified, and then reduced through facility design changes, they present significant opportunities for savings by reducing effort, resources, and management associated with performing work safely. WRF project #4236, Workforce Health and Safety: Prevention through Design​, was aimed at developing tools to help drive safety integration at the design phase. The project developed four models to support prevention through design (PtD) processes in water utilities of all sizes and types. This Webcast presented an overview of each of these models and explained how they can be used in water facility design and capital planning. It also showed how these tools can be used to assess existing facilities. Representatives from two participating utilities shared insights from their involvement in model testing and validation.
11/13/2014Webcast: Hexavalent Chromium Treatment with Strong Base Anion
On July 1, 2014, the nation’s first MCL specifically for hexavalent chromium [Cr(VI)] was adopted by the California State Water Resources Control Board Division of Drinking Water, formerly Department of Public Health.  In anticipation of and preparation for compliance with the MCL, the Soquel Creek Water District (District) led the WRF Tailored Collaboration project #4488, Hexavalent Chromium Treatment with Strong Base Anion Exchange (SBA-IX), for which this Webcast is based on.

This project conducted an in-depth investigation of SBA-IX for Cr(VI) removal and residual brine management alternatives.  While SBA-IX is a well-established drinking water technology for many contaminants, prior to the TC project, limited research had investigated SBA-IX for Cr(VI) removal.  Project #4488 revealed that, in the water supply tested, SBA-IX repeatedly achieved greater than 20,000 bed volumes of treatment prior to regeneration.  Brine recycle and treatment approaches also proved effective in minimizing waste residuals volumes.  The findings from project #4488 confirmed SBA-IX as the best available treatment technology for the District and prompted the District to construct the first SBA-IX system specifically for potable Cr(VI) treatment.  The report for this project has been posted on the WRF website.​
11/6/2014Minimizing Waste Backwash Water from a Biological Denitrification Treatment System
Biological denitrification (BDN) provides for a sustainable means of removing nitrate from groundwater supplies used for drinking water. Compared to conventi​onal nitrate removal technologies, such as ion exchange or reverse osmosis, BDN does not generate a high-salinity waste stream, and provides the added benefit of actually destroying the nitrate to nitrogen gas instead of simply accumulating it into a waste product. Many previous studies have demonstrated the viability of BDN for nitrate removal from groundwater. In WRF project #4470, the research team aimed at improving the applicability of BDN by evaluating the potential for recoverin/g much of the waste backwash water generated by the process in recognition of the fact that many groundwater wells do not have access to sewers with the capacity to take the full washwater production rate. The researchers also evaluated the potential for hexavalent chromium removal with the BDN process. In this Webcast, the results of the project were presented and discussed. The report for this project has been posted on the WRF Website.
10/7/2014Foundation Knowledge Webcast: Optimizing Engineered Biofiltration
Biological filters can allow for the achievement of multiple goals in a single treatment step. However, these benefits must be balanced with managing potential filter hydraulic challenges caused by biological fouling. This Webcast reviewed the results of project #4346, which sought to further validate previously identified biofilter enhancement strategies. In this tailored collaboration project with Dallas Water Utilities (DWU) and Tampa Bay Water, the research confirmed and further optimized nutrient and peroxide biofilter enhancements. This work also showed that significant hydraulic benefits could be achieved with biofilter pH optimization. Additional work included an evaluation on the impacts of these enhancement strategies (peroxide and/or nutrient addition) on the holistic optimization of upstream treatment processes.  Specifically, improved biofilter water treatment performance allowed a reduction in coagulant requirements at DWU, while providing the same level of treatment.

This Webcast benefited participants by reviewing the challenges and opportunities associated with biofilter optimization strategies. Recommendations on biofilter optimization approaches and a discussion on establishing reasonable expectations were also provided.
9/30/2014Foundation Knowledge Webcast: Effective Microbial Control Strategies for Main Breaks and Depressurization
​This Webcast presented the results and practical application of Project #4307​, Effective Microbial Control Strategies for Main Breaks and Depressurization. The purpose of the project was to improve utility responses to main breaks and depressurization events to better protect public health. A risk-based approach to main break responses was developed, resulting in four categories of main breaks with commensurate best practices for returning the main to service while reducing public health risks. Related outreach materials were developed to inform drinking water practitioners, including a Pocket Guide with Sanitation Procedures. The Webcast also provided updates on two key initiatives that are utilizing the results of this study: a process to update AWWA Standard C-651 (Disinfecting Water Mains) and the LPE (Low Pressure Event) Pilot Program being administered by the Missouri Department of Natural Resources. The project products are now available.
9/25/2014Acoustic Signal Processing for Pipe Condition Assessment
This Webcast, based on Project #4360​, provided an overview of acoustic signal processing for pipe condition assessment. Unique to pre-stressed concrete cylinder pipe (PCCP), individual wire breaks create an excitation in the pipe wall that may vary in response to the remaining compression of the pipe core. In non-PCCP, the structural excitation would require an external source acoustic pulse, causing a response indicative of relative pipe wall stiffness. The first part of the Webcast presented an overview of acoustic monitoring technologies for pipe condition monitoring. The second part of the Webcast detailed the experimental environment and intentionally inflicted damage to the pre-stressing wires in three specimens of PCCP.
9/16/2014Foundation Knowledge Webcast: WRF Webcast on Climate Change Communication for Water Utilities
Water utilities need to communicate the implications of climate change on water supplies to many audiences; for example, internal staff, Governing Board members, customers, and the press. This Webcast, based on project #4381​, shared insights, based on a nationally representative survey, on the public’s attitudes, beliefs, and actions concerning the nexus of community water and climate change. The findings may surprise you.  For example, 92% of Americans support their community water provider being a leader in preparing their community for climate change.  In addition to sharing the survey findings, this Webcast provided an overview of the pragmatic tools developed and tested in concert with the 13 water agencies who participated in the project.  Tools shared include a message mapping strategy (with worksheets) and risk based communication templates for how to talk to people who indicate they do not believe in climate change. The resources for this project are now available .

8/28/2014Managing and Mitigating Cyanotoxins in Water Supplies
​As shown by the recent events in Toledo, OH, cyanotoxins can cause major issues for water utilities and their customers. Cyanotoxins (also known as algal toxins) are natural toxins produced by cyanobacteria (blue-green algae) that may cause human health impacts if ingested with drinking water or by skin contact in recreational waters. The incidence of cyanobacterial blooms in surface water is a worldwide phenomenon and there is a risk that a changing climate, continued urbanization, and increased nutrient loading of source waters may contribute to more frequent and intense cyanobacterial blooms in drinking water sources in the future. The Webcast will provide information that will help utilities better understand issues associated with cyanotoxins and identify the necessary tools to prepare for and address potential cyanobacteria/cyanptoxin events.

This Webcast is based on the WRF/AWWA Partnership Project, Cyanotoxin Guides for Water Utility Managers (WRF #4548, AWWA/WITAF #270). This purpose of this project is to develop two cyanotoxin utility action guides designed for use by water utility management and staff, plus a list of research needs. The first guide will consist of a summary of cyanotoxin occurrence trends, potential health effects, preemptive and mitigation strategies, and mitigation challenges. This guide is intended to help water systems recognize if cyanotoxins may be an issue for their utility and what initial steps to consider. The second guide will be an action oriented synthesis of relevant literature for utility personnel and the water utility community, providing information necessary to guide development of a technically sound evaluation of cyanotoxins as a water quality concern for the drinking water supply and appropriate mitigation measures.

The Webcast will provide an overview of the major findings and action items from the project. The project guides will be available in early-2015.
8/21/2014Foundation Knowledge Webcast: Improving Water Quality and Consumer Satisfaction Using Guidance From the SMCLs
This Webcast, based on project #4537, provided an integrated overview of the EPA Secondary Maximum Contaminant Levels (SMCLs) in conjunction with up-to-date technical and consumer-based research that has occurred during the 35 years since their initial implementation in 1979. Utilities spend considerable funding to address the water quality and aesthetic issues addressed by these standards. Consumers decide the acceptability and value of their drinking water primarily based on a judgment of its taste, odor, and appearance. The Webcast presented an overview of the EPA Secondary Maximum Contaminant Limits, the rationale used to develop them, and current scientific knowledge related to their applicability. This information will aid utilities in developing a strategy for drinking water quality and consumer acceptability.
7/23/2014Foundation Knowledge Webcast: 2014 Focus Area Subscriber Feedback Webcast
The purpose of this Webcast was to obtain feedback from subscribing utilities on the relevance of the 10 existing WRF Focus Areas. In particular:

- How important are the 10 Focus Area issues or challenges to subscribing utilities and the water sector overall?
- What issues or challenges has WRF missed with the Focus Area research program?
Participants were given the opportunity to respond to these questions for each of the 10 Focus Areas via a real-time interactive survey, and by typing in responses to questions. Participants were provided background information on each of the 10 Focus Areas prior to the Webcast, and were given a short overview again during the actual Webcast.

7/10/2014Foundation Knowledge Webcast: Desalination Concentrate Management Policy Analysis for the Arid West
Brackish groundwater desalination is a climate-independent water supply option in the arid regions of the western United States where freshwater options are limited.  However, inland desalination is only viable when the concentrate management challenges can be overcome. This archived Webcast, hosted by the WateReuse Research Foundation on July 10, 2014, summarized key findings from project #4417​, Desalination Concentrate Management Policy Analysis for the Arid West. The project was jointly funded by the Water Research Foundation and the WaterReuse Research Foundation, and led by El Paso Water Utilities (EPWU), in coordination with the Consortium for Hi-Technology Investigations in Water and Wastewater (CHIWAWA), several consultants, and WateReuse Research Foundation.

Listen to Ed Archuleta, retired CEO/President at El Paso Water Utilities and past Chair of the WRF Board of Trustees, and Dr. Robert Raucher, Senior Vice President at Stratus Consulting Inc., highlight the project findings, recommendations, and activities to further address the challenge of concentrate management for inland municipal water suppliers.
6/24/2014Biofiltration Knowledge Base
This Webcast introduced the Biofiltration Knowledge Base for Water Research Foundation Project 4459, "Development of a Biofiltration Knowledge Base". The knowledge base is intended to capture the experiences and best management practices from North American water utilities currently in the process of implementing or operating high rate aerobic biofilters. Currently, the knowledge base contains information from 26 full-scale facilities broken into four phases of implementation ― planning, evaluation, design, and operation. This Webcast will summarize these case studies and provide guidance for accessing, using, and contributingto the web-based knowledge base. The Knowledge Base is now available to use and the final report for this project will be available in early 2015.
6/19/2014What are the Best Economic Options for Managing Leakage?
This Webcast will discuss the newly completed project, Real Loss Component Analysis: A Tool for Economic Water Loss Control (project #4372), which will help managers analyze and reduce water utility system leakage in the most cost effective way. The project produced a free user-friendly model that is a major improvement in standard leakage component analysis for the water utility community.
The model supports AWWA M36 and uses the IWA/AWWA Water Audit as input. Ten North American utilities assisted with developing and beta testing the model. Additional funding was provided by the U.S. Environmental Protection Agency. The webinar will specifically cover:
• Goals and Background of Project 4372
• Findings of a Literature Review
• Purpose and Outputs of the Model
• Recommendations on Applying the Model
• Next Steps on Outreach and Training
6/3/2014Foundation Knowledge Webcast: Benefits and Disadvantages of Using No Disruption Repair Techniques
The management of planned activities on water networks is coming under growing pressure to ensure that interruptions to water supplies are prevented or minimized. This has resulted in increasing use of ‘no disruption’ repair techniques. This Webcast reported on the results of project #4513, which undertook a technical appraisal of water company experience of pipeline repair using a range of techniques, covering traditional (‘disruptive’) and ‘no disruption’ repair, with the aim of assessing the impact of the method selected on short- and long-term network performance and on the consequent service to customers.
During the course of the project, data was analyzed from a number of water companies within the United Kingdom to assess the impact of different network repair technologies on subsequent performance of the water distribution network. A Decision Support Tool was developed to enable water companies to select the best technique to use in various circumstances. The Webcast presented the project findings along with guidance on what data to collect in the future to refine this information and support further appraisal.
4/22/2014Foundation Knowledge Webcast: Identifying Gaps in Understanding the Benefits/Costs of Boil Water Advisories as a Public Health Protection Measure
This Webcast provides the results of Water Research Foundation project 4385, "Identifying the Gaps in Understanding the Benefits and Costs of Boil Water Advisories". The results include a strategic roadmap for future data gathering, analysis, and research aimed at increasing the benefits and reducing the costs of boil water advisories (BWAs), and a systematic review of the practices and results of boil water and other types of advisories (such as do not drink and do not use).  One of the key findings to be explored in this Webcast is how to better target precautionary BWAs so that they focus on the situations where health risks are relatively more likely to be evident (and, conversely, minimize the use of BWAs in instances where there is very low likelihood of a public health risk reduction).  This includes developing risk-based criteria that utilities and regulatory/public health officials can quickly apply to target BWAs. The final report for this project is now available on the website.
4/10/2014Foundation Knowledge Webcast: Pressure Management: Industry Practices and Monitoring Procedures
​Most systems tend to operate at much higher pressure than needed, resulting in increased energy use, increased non-revenue water loss, and excessive main breaks. Project #4321, Pressure Management: Industry Practices and Monitoring Procedures developed guidance on best practices and cost/benefits of implementing an optimized pressure management program. The project included an analysis of a year-long pressure monitoring program from 22 utilities. This Webcast will focus on these results and a survey of pressure management practices, examining the case study examples and providing recommendations to improve pressure management in drinking water distribution systems. The final deliverables for this project are available on the website.
4/1/2014Broadening the National Dialogue on Contaminants of Emerging Concern and Public Health
Inter-disciplinary communication on the potential human health risks of contaminants of emerging concern (CECs) in drinking water is currently lacking. Water utilities would benefit from partnerships with public health professionals who could provide information on the safety and quality of water supplies. To address this need, the Water Research Foundation hosted an inter-disciplinary workshop as part of project #4463 to broaden the national dialogue on this topic last July. The overall objective of this Webcast is to present the key findings from the workshop, and to provide the water community with a first-hand opportunity to better understand the public health perspective on CECs in drinking water. The deliverables for project #4463 are available on the website
3/6/2014Performance Benchmarking for Effectively Managed Water Utilities
WRF funded project #4313 to serve its subscribers and the water and wastewater sectors by providing a practical tool to utilities to conduct assessments and strategically develop key organizational attributes to meet specific goals.

This Webcast included three primary topics:

- Background on the project and summary of primary findings and products
- Description of the recommended process for conducting a self-assessment
- Illustration of how to use the benchmarking tool developed for the project to conduct a self-assessment

The background segment of the webcast described how the project team, with the aid of WRF, participating utilities, the Project Advisory Committee, and six industry associations, developed practice areas and performance measures for each of the Ten Attributes of EUM. The recommended process segment will describe recommendations for identifying members of a benchmarking team, and how team members should be engaged to develop a customized self-assessment and score current and target performance. The final segment of the webcast demonstrated how the benchmarking tool developed for this project can be used to efficiently support the self-assessment process.
2/25/2014Water Footprint and Sustainable Water Utilities
The water footprint concept has been used by agricultural, commercial, and industrial water users to measure and report their water consumption, assess the magnitude of environmental impact(s) arising from this consumption, and identify opportunities for risk mitigation strategies that promote sustainable water use. However, water utilities have not studied and documented the application of this concept in the same manner that other industries have. This Webcast, based on project #4378, will present (1) the growing body of information on the water footprint concept, (2) opportunities for integrating the water footprint concept into water utility planning efforts as a broader means of achieving and maintaining sustainable communities, and (3) guidance that water utilities can follow for implementing this concept within their organizations. The final report for this project is now available.
2/13/2014Defining a Resilient Business Model for Water Utilities - Part 2
This second of two Webcasts based on Project #4366 will introduce the audience to practices that have the potential to improve the financial resiliency of the water utility industry. The Webcast will present examples of current, emerging, and “out of the box” strategies available to utilities to build a resilient business model.
2/4/2014Defining a Resilient Business Model for Water Utilities - Part 1
The first of two Webcasts based on Project #4366 will introduce the audience to an assessment of the financial condition and revenue model of water utilities in North America and the factors influencing financial performance. While it seems most research and high-profile policy papers today focus on the “cost” side of the financial balance utilities must navigate, this project primarily addresses the revenue and rates side of the equation. The analysis clearly shows that there is not one generalizable “new normal” or inevitable pre-ordained financial outcome for the industry. There are clearly differences between regions, states, and utilities. The analysis shows that although the prevailing revenue model has posed significant problems for many utilities in the recent past, it continues to serve many utilities relatively well. The project has been completed and a final report and two spreadsheet tools are now available.
1/30/2014Foundation Knowledge Webcast: Legal Protection and Claims Management from Infrastructure Failure
This Webcast is based on WRF Project 4369, which provides an industry guide for drinking water utilities on legal protection and claims management issues before, during, and after infrastructure failure events. The guide is based on research, case studies, and interviews with operators and risk management professionals from a cross-section of leading North American water utilities. The compilation of best practices will help utilities improve asset management programs and emergency response practices to minimize legal and claims management issues following failure events; and assess and limit potential liability, both for water system repairs and from damages, to others that can arise from a water line break. The guide provides background information on the legal principles governing this area of the law and effective measures utilities can employ both to defend themselves from the claims of those asserting damages from a break and to prosecute their own claims when breaks are not caused by either the utility's actions or failure to act. It includes checklists of recommended practices before, during, and after failure events. This project also developed three brief training videos that highlight the recommended practices. The guide and videos are now available.
12/10/2013Foundation Knowledge Webcast: Consumer Perceptions and Attitudes Toward EDCs and PPCPs in Drinking Water
​Although media reporting on health risks has a tendency to stir up worry, this worry is often misplaced when reports involve the misrepresentation of unsubstantiated scientific evidence. The presence of endocrine-disrupting compounds (EDCs) and pharmaceuticals and personal care products (PPCPs) in the water supply has attracted substantial media attention, particularly in the United States. This has been followed by intense policy discussions, despite the fact there is no concrete evidence to suggest a risk to public health. This Webcast presented the results from project #4323, which explored the public’s perspective on the health risks posed by contaminants, their science, and regulation in an effort to support the water community in the development of fresh and effective communication. The final report and other deliverables for this project are now available on the project page.
12/3/2013A Monitoring and Control Toolbox for Biological Filtration
​​Biological filtration is rapidly being embraced and implemented by the drinking water industry in North America. However it is often implemented in an incidental manner. Managed biological filtration involves application of sound scientific and engineering principles to the design, monitoring, operations, and control of the biological processes as well as the physical filtration process. To this end, practical monitoring and control tools for biological filtration are needed. Project #4231 identified and evaluated a number of tools at numerous utilities across North America. These tools included existing and innovative methods for on-line and off-line analysis of various forms of organic carbon that are relevant to biological filtration, biological activity in the biological filters, general water quality parameters, and operational parameters. In addition, various control tools were evaluated. The outcome of the project includes a final report and guidance manual, both of which are currently available. This Webcast included descriptions of the monitoring and control tools and practical tips on how they can be used to enhance biological filtration operations and performance.
11/12/2013Foundation Knowledge Webcast: Developing Surveillance and Response Systems for Water Distribution Systems
This Webcast presents the results from project #4430, Developing Surveillance and Response Systems for Water Distribution Systems. The Water Research Foundation funded this project to gather lessons learned from the nationwide deployment of Surveillance and Response Systems (SRSs) (formerly Contamination Warning Systems [CWSs]) and share this information with the entire industry. Lessons learned were derived from utilities that implemented both full scale and partial SRSs. A full scale SRS includes online water quality monitoring, customer complaint surveillance, enhanced security monitoring, public health surveillance, system integration, and consequence management (which includes sampling and analysis). The final report is now available on the #4430 project page.
11/7/2013Foundation Knowledge Webcast: Water Utility Executive Leadership for the 21st Century
​Despite the centrality of executive leadership to utility success, very little is known about water utility chief executive officers (CEOs). Who are utility CEOs? How do they think about their work? What do CEOs do on the job? This Webcast presents highlights from project #4342, which begins to answer these questions with the first comprehensive study of water utility executives in the United States. The project presents the defining characteristics of the executive corps that lead U.S. water utilities, and define a starting point for the selection and development of future executive leaders.  The report for the project is now available.
10/24/2013Foundation Knowledge Webcast: Steering Innovation in Water Utility Finance and Management
The water industry is transforming from one of known challenges and steady growth that can be addressed by engineering solutions to one of a spectrum of uncertainties. These uncertainties will likely require a suite of strategies to mitigate and master the most probable and consequential trends and associated risks. Utility responses to uncertainties, risks, costs, and innovative opportunities will help shape public perceptions of water utilities and their leaders, and in turn, shape the state of the industry. This Webcast presented a summary of a forum of over 20 high level managers from many of WRF’s large water utility subscribers and their assessment of trends in the industry, the risks associated with these trends, and relevant strategies. The forum was conducted as part of project #4506.  The final report is now available.
9/26/2013Foundation Knowledge Webcast: Changes in Water Use Under Regional Climate Change Scenarios
This Webcast presents findings from project #4263, which examined the potential impacts of future climate scenarios on water demand. The demand for water is highly dependent on climate, and weather-sensitive water uses typically comprise a large component of total water use. Geographical differences in climate and variability in observed weather conditions lead to differences in water usage patterns across different regions and seasonal time periods. Changes in climate from historical conditions, both in terms of mean weather conditions and variability, should be expected to influence the demand for water. The Webcast will illustrate the importance of climate in shaping water demand patterns and will estimate potential impacts from future climate scenarios for a set of case study utilities.
9/19/2013Foundation Knowledge Webcast: A Decision Tool for Earthy/Musty Taste and Odor Control
The presence of MIB and/or geosmin, which cause taste and odor issues, can create significant public relations problems for water utilities. This Webcast presents the results from project #3032, which explores the effect of water quality on human sensitivity to earthy/musty odors and public perceptions, and presents a decision-making tool to help utilities develop reasonable and defensible treatment goals for managing geosmin and MIB taste and odor events. The final report and decision-making tool for this project are now available.
8/13/2013Foundation Knowledge Webcast: Water Quality Impacts on Cr(VI) Removal and Cost
By the time of this Webcast, the California Department of Public Health is expected to have published a proposed Maximum Contaminant Limit (MCL) for hexavalent chromium (Cr[VI]) in drinking water. The U.S. Environmental Protection Agency is also evaluating new toxicological data on Cr(VI) as part of an effort to evaluate the need to develop a national primary MCL for Cr(VI) in drinking water. This Webcast will address these developments by presenting the results of WaterRF project #4450​, which evaluated the removal of Cr(VI) from 10 groundwater sources in an effort to understand the impact of different water quality parameters on the performance and cost of three Cr(VI) treatment technologies: Weak-Base Anion (WBA) resin, Strong-Base Anion (SBA) resin, and Reduction-Coagulation-Filtration (RCF). Based on the treatment performance, capital and annual Operations & Maintenance cost estimates were developed for each treatment technology. A Web-based Cr(VI) treatment cost tool was also developed and posted on a dedicated website (www.CrVITreatmentCosts.com). The Webcast presents the capital and annual cost estimates developed, and includes a discussion of the assumptions behind the cost tool and instructions on how to use it. Both the Webcast and Cr(VI) cost tool are free and available to the public.
8/8/2013Foundation Knowledge Webcast: Impact of Galvanic Corrosion on Partial Lead Service Line Replacement
This Webcast presents findings from project #4349, supported by the Water Research Foundation, the District of Columbia Water and Sewer Authority, and the Providence Water Supply Board, to examine the issue of lead in drinking water following partial lead service line replacements (LSLRs). Partial LSLRs are the result of divided ownership of the customer service line, and they can result from required regulatory replacements or can be incidental to infrastructure renewal or repair efforts by the utility. The Webcast reports on two experimental programs that examined lead release in controlled laboratory settings using different types of commercially available couplings. It also reports on long term field data from partial LSLRs in the two participating utilities, which were done as part of large lead service line replacement programs. The final report for this project will be available before the Webcast on the #4349 project page.
7/11/2013Foundation Knowledge Webcast: State of the Science of Opportunistic Pathogens in Premise Plumbing
This Webcast presented information on the state of the science of opportunistic pathogens in premise plumbing (OPPPs) based on a WaterRF report and Expert Workshop (project #4379). The Webcast focused on five model OPPPs: Legionella pneumophila, Mycobacterium avium Complex (MAC), Pseudomonas aeruginosa, Acanthamoeba spp., and Naegleria fowleri. Current understanding of their epidemiology, microbial ecology, methodology, and engineering controls was discussed.

6/25/2013Foundation Knowledge Webcast: Risk Governance: An Implementation Guide for Water Utilities
This Webcast discussed the results from the recently published WaterRF report, Risk Governance: An Implementation Guide for Water Utilities (project #4363). The Webcast addressed issues of organizational culture, Board level structures and discussions on risk, practical steps for implementation, and international good practices. Participants will gain an appreciation of key drivers for good risk governance, the role of the appointed risk manager, and the key features of a risk management capability. Presenter: Simon Pollard, Cranfield University.
6/20/2013Foundation Knowledge Webcast: The EDC Network for Water Utilities
​The EDC Network for Water Utilities provides a secure website resource for utilities to share best practices, documents, other tools, and materials related to EDCs and PPCPs. This Webcast introduced utility staff to The EDC network, with a focus on accessing available resources, networking, and sharing information. Presenters: Elisabeth L. Hawley and Rula A. Deeb, ARCADIS.
6/4/2013Foundation Knowledge Webcast: Guidance for the Treatment of Manganese
Manganese (Mn) is a frequent treatment challenge for drinking water utilities. In 2006, the EPA estimated that 13% of all groundwater and 21% of all surface water systems provide treatment for Mn. Yet given the prevalence of Mn occurrence and the multiple methods that utilities use to deal with Mn, there are few comprehensive references regarding the management of Mn. To meet this need, the project team has prepared a comprehensive manual titled, Guidance for the Treatment of Manganese (Project #4373).The manual is intended to provide guidance to utilities and water professionals for the effective control of Mn through source water management and the design and operation of Mn treatment processes.
5/17/2013Foundation Knowledge Webcast: UV System Start-Up, Operations, and Avoidance of Off-Spec Water
This Webcast focuses on helping both operations and engineering staff at utilities to understand what the priorities are for running a UV system and a brief overview of why they are important. The Webcast was developed in conjunction with staff from Greater Cincinnati Water Works to enhance their training as they learn to better operate their new UV system.
5/16/2013Foundation Knowledge Webcast:Advances in PAC Adsorption for DBP Precursor and Micropollutant Removal
Recent developments in the production of powdered activated carbon (PAC) have resulted in a plethora of products that have the potential to expand the use of PAC beyond traditional treatment objectives such as taste and odor control. This Webcast summarizes results from recently completed WaterRF project #4294 that evaluated the use of PAC for the combined control of disinfection by-product (DBP) precursors and organic micropollutants.
