Characterization and Treatability of TOC from DPR Processes Compared to Surface Water Supplies (Reuse-15-04)
WE&RF has awarded CH2M with a contract to develop a site-specific, feasible, and scientifically defensible framework for utilities pursuing direct potable reuse to demonstrate to stakeholders that DPR water is “safe” from an organics perspective.
Outbreaks of Illness Associated with Recreational Water — United States, 2011–2012
This CDC Morbidity and Mortality Report investigates the outbreaks of illness as a result of exposure to chemicals and infectious pathogens in recreational water.
Preventing Eutrophication: Scientific Support for Dual Nutrient Criteria (Fact Sheet)
U.S. EPA recently released an updated fact sheet on “Preventing Eutrophication: Scientific Support for Dual Nutrient Criteria.” The purpose of the updated fact sheet is to describe the scientific basis supporting the development of criteria for both Nitrogen (N) and Phosphorus (P) to prevent eutrophication and the proliferation of harmful algal blooms.
The Road Toward Smarter Nutrient Management in Municipal Water Treatment - The Johnson Foundation at Wingspread
WERF's Senior Program Director, Amit Pramanik, participated in this recently published report discussing nutrient management in municipal water treatment.
Your Opportunity to Apply WERF'S Nutrient Modeling Toolbox: Webcast
WERF is interested in applying the Nutrient Modeling Toolbox nationwide at different sites both locally and regionally based on the site specific question to address your numeric criteria. Please contact lolabode@werf.org or (571) 384-2109 if you know of any site(s), region(s) or state(s) that could benefit greatly from this opportunity. For more background information, this webcast provides an overview of the Nutrient Modeling Toolbox, it’s intended uses, objectives, including assisting states in developing numeric criteria (both model selection and application), modeling nutrient loadings, water quality impairment causes, and UAA support.

Modeling Guidance for Developing Site-Specific Nutrient Goals (LINK1T11)
This research report presents guidance and tools for the use of models to set waterbody-specific nutrient goals, including Numeric Nutrient Criteria NNC and allowable nutrient loadings. The developed Nutrient Modeling Toolbox contains 30 models capable of quantifying the relationship between nutrient loads and their impacts in terms of water quality or ecological response indicators.
WERF/NACWA Use Attainability Analysis Handbook
This handbook is a collaborative effort between WERF and the National Association of Clean Water Agencies (NACWA). It provides insights into the UAA process, into the restoration potential (if applicable), and into natural and human factors. Order the handbook, or download an executive summary.
