|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.
|Online Water Quality Sensors and Monitors Compendium|

|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.

The Relative Cost of Safety for Tasks (R-CoST) model is a quantitative tool for comparing alternative designs and task methods within each of five areas (referred to as task groups). The Total Cost of Safety for Tasks (T-CoST) model is a tool that aims to account for ongoing costs in a more comprehensive manner. Lastly, the Material Handling Cost (MHC) model incorporates an adaptation of the T-CoST model approach specifically for manual material handling tasks. The TCM, R-CoST, T-CoST, and Material Handling models are designed to aid in deciding among alternatives based on credible differences in ongoing costs.

|Desalination Intake Decision Tool|
The decision process developed in project 4080 was turned into this software tool. The software walks the reader step-by-step (tab-by-tab) through the evaluation process. The user is prompted to answer a series of questions. Most queries have “Note” sections where the user can add additional documentation related to the questions as desired. As the decision tool is targeted at developing an intake development plan, it is assumed that the user has already determined the desalting process scenario to the extent that he/she knows the volume of feed water the process will need.
If intake design options are deemed unfeasible at any point in the process, they are eliminated from further consideration. This process delivers technically defensible options that help a user evaluate and select which options are best for the application.
