The objective of this project is to build on existing work by developing updated operational guidelines for optimizing nutrient removal plant performance. This will be accomplished through additional research or demonstration, and from documented performance for nitrogen and phosphorus removal through the use of tools such as operational best practices, online instrumentation, control capabilities, model-based controls, and smart systems.

The objective of this study is to evaluate PFAS occurrence in U.S. wastewater treatment plants and determine the fate of PFAS compounds during wastewater treatment.

To evaluate analysis tools for, and risks from, implementing and/or changing corrosion control treatment (CCT), and to explore the potential impact of various source water or treatment changes to CCT. To develop a framework for how to assess current CCT and under what circumstances CCT should be re-evaluated. Impacts to both lead and copper should be explored.

The objective of this roadmap workshop is to produce a robust and comprehensive discussion to set research priorities for confirming linkages between receiving water quality, wastewater discharge, and other sources.

Project Objective:
• Based on successful application of Intelligent Water Systems (IWS ) approaches, define concepts and components of an effective data-driven, digital utility/smart water system, including culture, management and skill sets.
• Leverage ongoing advancements in sensor, data management/analytics, and digital communication technologies.
• Facilitate the use of IWS/data-driven digital

To evaluate the experiences of water utilities that have or are currently integrating decentralized reuse and treatment systems into their portfolios through answering the following questions:
• What are the key drivers, decision factors, and costs?
• How do successfully implemented decentralized systems balance impacts to water quality and quantity, internal operations, relationships with other water agencies and the local government, business community, and general community so as to provide social equity?

This project has two major research objectives:
• To identify the most effective strategies for integrating public education and engagement elements at demonstration facilities for potable reuse
• To develop outreach materials that present science and research on potable reuse in general

Project Objectives:
• To assess the effectiveness of flushing to reduce the levels of Legionella in service lines and premise plumbing pipes, either as a corrective response or for ongoing maintenance.
• To evaluate the use of water quality parameters as an indicator for effectiveness of flushing.
• To develop data-driven guidance on applicability and effectiveness of flushing as a method for Legionella control.

Project Objectives:
• To assess the microbial risks and potential impacts from stormwater collection and onsite reuse to help establish appropriate best management practices for stormwater harvesting/reuse and other stormwater control measures.
• To better understand the severity of stormwater microbial contamination from fecal indicator bacteria and other pathogens, types and concentration of microbes, as well as growth over time in a variety of common stormwater scenarios.
• To use the Risk-Based Framework for the Development of Public Health Guidance for Decentralized Non-potable Water Systems (SIWM10C15) to develop a “Roadmap” that can guide utilities/stormwater managers in assessing site-specific microbial risks associated with stormwater collected for intended uses.
• To synthesize key methods and strategies in assessing baseflow and rain/snowmelt event microbial indicators to aid risk management based on evolving log-reduction pathogen targets.

Project Objectives:
• Evaluate the impact of bromate control strategies on ozone oxidation of compounds of emerging concern (CECs).
• Investigate the impact of bromate control strategies on pathogen inactivation.
• Investigate the impact of bromate control strategies on the removal of total organic carbon (TOC) and CECs in downstream biofiltration processes.
• Investigate the impact of bromate control strategies on microbial activity and the need for quenching upstream of biofiltration.

Project Objective
The objective of this project is to develop a technical brief addressing ecological and human healthimpacts of compounds of emerging concern (CECs)/trace organic compounds (TOrCs) in the One Water context (i.e., wastewater, receiving water, urban stormwater runoff, recycled water, groundwater, and drinking water). The technical brief will consist of plain English fact sheets written in layman’s terms that:
• Synthesize the current definitions of compounds of interest, unregulated compounds of concern, and newly emerging compounds.
• Summarize the state of the knowledge (i.e., what we know and don’t know) about these compounds in the One Water context.
• Describe currently used and promising methods to identify, measure and assess the impact of CECs, as well as the most effective treatment processes for wastewater, recycled water and drinking water.
• Evaluate the potential human health and ecological effects of CECs.
• Identify current management strategies for CECs.

Project Objectives:
• Conduct a global literature review and survey on feedstock pre-treatment technologies and management strategies, including the characteristics of the materials resulting from the application of various technologies with a focus on applicability and implementation in the U.S.
• Evaluate existing pre-treatment technologies and systems including throughput, costs, batch or continuous mode, O&M requirements, footprint, reliability (uptime/downtime), operability, final end product quality, etc., with a focus on municipal wastewater anaerobic digester operability and maintainability.
• Perform a review of a minimum of six wastewater facility case studies that provide a broad view of the industry and an overview of practical approaches for pre-treatment to help facilities identify appropriate pre-treatment technologies and strategies to meet their needs.
• Engage with utility subscribers through the relevant LIFT Focus Groups and other LIFT activities.
