CU SRP Community Engagement PI Yan Zheng and and USGS Hydrologist Joseph Ayotte together have edited a special section on arsenic for the journal Science of the Total Environment (STOTEN), Volume 505, 1 February 2015. Their summary paper, “At the crossroads: Hazard assessment and reduction of health risks from arsenic in private well waters of the northeastern United States and Atlantic Canada” is the first in a collection of thirteen papers that provides state-of-the-art information on arsenic (AS) hydrogeochemistry, effectiveness of household well treatment systems, and the testing and treatment decisions of private well owners in several northeastern U.S. states and in Nova Scotia, Canada. The Zheng-Ayotte paper and the special Arsenic section are available now online (see link below).
A total of 5 papers in the STOTEN special issue are also co-authored by Columbia SRP scientists and their partners. They include CU SRP Community Engagement and Research Translation Core scientists Yan Zheng and Sara V. Flanagan, CU project scientist Martin Stute, former trainee Qiang Yang (now Lamont Associate Research Scientist), former CU SRP post doc Beth O’Shea (now Assistant Professor at University San Diego), and government collaborators Joseph Ayotte (USGS, New England Water Science Center New Hampshire-Vermont Office), Robert Marvinney (Maine Geological Survey), Charles Culbertson (USGS , Maine Water Science Center), and Steve Spayd (NJ Geological Survey).
Zhang and Ayotte conclude in their summary that there must be an overall, long-term strategy to reduce exposure to vulnerable populations in regions where levels of arsenic in well-water are high. More consideration is needed to encourage well testing, treatment, access to alternative water sources, and possible implementation of local, state, and regional private well-water regulations.
