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...
Standing Operating Procedures (SOP) for the Development of Provisional Advisory Levels (PALs) for Hazardous Chemicals
(PUBLISHED REPORT) [Published : Feb 28, 2018]
Report: This report has been completed under a peer review plan that included internal technical review and external peer review. It distinguishes the types of chemical risk information necessary to support emergency response decisions and emphasizes the importance of having adv...
The effectiveness of disinfection and flushing procedures to prevent coliform persistence in aircraft water systems
(JOURNAL) [Published : Dec 24, 2018]
Maintaining safe water on board commercial aircraft is critical to the safety of passengers and compliance with regulations. The conclusions from this study can help commercial air carriers deliver safe water by indicating that coliform bacteria are not persistent on aircraft plu...

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...

CANARY Eases Water Quality Event Detection
(JOURNAL) [Published : Apr 01, 2017]
CANARY is a free EPA software product used to enhance the detection of contamination incidents in distribution systems (i.e. Event Detection System) using typical water quality sensors such as those measuring free chlorine, total organic carbon, and electrical conductivity. Worki...
Decontamination of Bacillus spores adhered to iron and cement-mortar drinking water infrastructure in a model system using disinfectants
(JOURNAL) [Published : Feb 01, 2017]
Bacillus spores are persistent on common drinking water infrastructure surfaces such as corroded iron and cement-mortar. Due to their resistance to disinfection, inactivation of spores can be used as a benchmark for decontamination of biological agents from drinking water infrast...
