|Alternative Source Water Assessment Tool|
As part of project #4665, the Alternative Source Water Assessment Tool (A∙SWAT) was developed to aid utilities in screening the treatability of their stormwater and/or treated wastewater at a conventional drinking water treatment plant, and to calculate water quality requirements based on finished water goals and conventional water treatment plant performance. The A∙SWAT establishes a relative suitability for treatment of local stormwater or treated wastewater based upon site-specific water quality and typical conventional treatment performance. The A∙SWAT provides high-level screening of source water quality based upon the 14 stormwater or 11 treated wastewater water quality contaminants that are most commonly cited in prior studies at concentrations that are higher than those in more traditional source waters.
An A∙SWAT User Guide was developed and is both included with the webtool and available as Appendix C of the project #4665 research report.

|Demo for an Advanced Real-time Monitoring and Decision Aide (ARMADA)|
An alternative, “multi-site approach” is demonstrated here using an experimental computer program called the Advanced Real-time Monitoring And Decision Aide (ARMADA). The concept is that water quality signals at a “target site” can be “filtered” to remove variability due to known (measured) causes. The causes are represented by data that describes incoming water quality from upstream sites, and hydraulics operations such as pumping and tank cycling. The filtering is performed by empirical (curve fitting) models that predict target water quality from known causes, thereby accounting for their effects. The models’ prediction errors (the differences between the target’s measured and predicted water quality values) represent variability due to unknown causes, such as a contamination event that originates between sites. A statistically large prediction error causes a notification.

The updated compendium will go live by January 2017. Thank you for your patience.
|Database of Drinking Water Qualities in the United States and Canada|
Project 4191 was designed to identify and prioritize key water quality characteristics and changes that might adversely impact the performance and leaching of nonleaded brasses in drinking water distribution systems over typical component lifetimes. The formation of the passivating layers, and thus the corrosion and metal-release behavior, is mainly driven by material property and water quality. To cover both of these factors, it was necessary to identify so-called “corner waters,” which represent a high percentage of the drinking water distributed in North America. Based on statistics and the experiences of water utilities and other drinking water specialists, five corner waters were identified that were used to perform the long-term migration experiments (see Chapter 2). In this context, a database was created in which the distributed water qualities in the large cities and metropolitan regions of the United States and Canada were summarized.
