Electrolyte Selection and Microbial Toxicity for Electrochemical Oxidative Water Treatment Using a Boron-doped Diamond Anode to Support Site Specific Contamination Incident Response
(JOURNAL) [Published : Apr 06, 2018]
This journal article study addresses such concerns by demonstrating successful boron-doped diamond (BDD) electrochemical advanced oxidation process (AOP) pre-treatment for contaminated waters prior to discharge to wastewater treatment facilities.
Mass Imbalances in EPANET Water-quality Simulations
(JOURNAL) [Published : Apr 06, 2018]
This journal article examines EPANET, which is widely employed to simulate water quality in water distribution systems. However, the time-driven simulation approach used to determine concentrations of water-quality constituents provides accurate results, in general, only for smal...
Persistence and Decontamination of Radioactive Cesium in a Model Drinking Water System
(PUBLISHED REPORT) [Published : Jul 17, 2018]
The objective of this report was to evaluate the persistence of radioactive cesium-137 (Cs-137), on concrete-lined, copper, and polyvinyl chloride (PVC) pipe, and possible decontamination approaches. During this study, conditions within operational drinking water pipes were simul...
Shipment, Preservation, and Analysis of Chemical Warfare Agents (CWAs) in Environmental Matrices
(SUMMARY) [Published : Sep 03, 2018]
The document is intended to be applicable to consequence management activities that EPA will be involved with and will require remediation of contaminated areas by an urban release of chemical warfare agents (CWA). The document summarizes the gaps that have been addressed towards...

Adsorption of Malathion onto Copper and Iron Surfaces Relevant to Water Infrastructure
(JOURNAL) [Published : Nov 01, 2017]
This study investigated the adsorption of malathion to copper and iron surfaces including pipe specimens similar to those in drinking water infrastructure.
Advanced Oxidation in Challenging Waters: Effects on Performance and Microbial Toxicity
(PAPER IN NON-EPA PROCEEDINGS) [Published : Jan 01, 2017]
Advanced oxidation processes (AOPs) may be a viable strategy to treat waters contaminated with a variety of organic contaminants. Results from this study may help design effective treatment strategies for water matrices containing substances that interfere with AOP treatment, a t...
