Using Phosphate-Based Corrosion Inhibitors and Sequestrants to Meet Multiple Water Treatment Objectives
To provide guidance for dosing and/or adjusting phosphate-based corrosion inhibitors and sequestrants while minimizing metals release (lead, copper, and others) and avoiding unintended consequences.
Assessment of Molecular Techniques to Detect and Predict Cyanotoxin Occurrence
Project Objectives: Develop a field guide to support drinking water system cyanotoxin risk management strategies
Understanding the Mechanisms of Chlorine and Chloramine Impact on Opportunistic Pathogens in Distribution Systems
The goal of this project is to elucidate the mechanisms of chlorine and chloramine on opportunistic pathogens (OPs).
Development of Innovative Predictive Control Strategies for Nutrient Removal
Develop one or more artificial intelligence (AI)/machine learning (ML) predictive tools for nutrient removal.
Demonstrate testing of new predictive control strategies, with a focus on Technology Development Level 2 or 3 (Technology Readiness Level 6-8), with field testing at one utility. This field testing will be complemented by desktop analysis comparing predictive and reactive control strategies.
Technologies and Approaches to Minimize Brominated and Iodinated DBPs in Distribution Systems
This project aims to develop creative and novel techniques and approaches to minimize the formation of currently unregulated brominated and iodinated disinfection byproducts (DBPs) in the distribution system considering practical applicability and economic feasibility in the operation of existing treatment systems.
Establishing Seasonal Targets for Receiving Waters: Rethinking Wet Weather versus Dry Weather Expectations
1. Initiate a first phase project to evaluate the implications of wet weather conditions on permitting and pollutant load reduction targets as a baseline for future studies.
2. Produce a well-documented summary of the currently available tools and study results evaluating watershed pollutant loads and receiving water responses under wet weather and dry weather conditions (including different hydrological conditions).
3. Outline possible implications on target setting (i.e., surface water and effluent goals for pollutants; may include designated uses) and regulation.
4. Use the available information to generate recommendations for wet weather target setting.
