High Arsenic Levels Well Water Testing Found in 8 Percent of Groundwater Wells Studied in Pennsylvania

The Need for Well Water Testing In Pennsylvania and other states

NEW CUMBERLAND, Pa. – Eight percent of more than 5,000 wells tested across Pennsylvania contain groundwater with levels of arsenic at or above federal standards set for public drinking water, while an additional 12 percent – though not exceeding standards – show elevated levels of arsenic. 

These findings, along with maps depicting areas in the state most likely to have elevated levels of arsenic in groundwater, are part of a recently released U.S. Geological Survey study done in cooperation with the Pennsylvania Departments of Health and Environmental Protection.

The results highlight the importance of private well owners testing and potentially treating their water.  While public water supplies are treated to ensure that water reaching the tap of households meets federal drinking water standards, private wells are unregulated in Pennsylvania, and owners are responsible for testing and treating their own water.

For this study, USGS scientists compiled data collected between 1969 and 2007 from industrial, public, and private wells. Arsenic levels, along with other groundwater quality and environmental factors, were used to generate statewide and regional maps that predict the probability of elevated arsenic.   The study examined groundwater from carbonate, crystalline, and shale/sandstone bedrock aquifers, and from shallow glacial sediment aquifers. Similar maps have been produced for other states.

“This research is not intended to predict arsenic levels for individual wells; its purpose is to predict the probability of elevated levels of arsenic in groundwater to help public health efforts in Pennsylvania,” said USGS scientist Eliza Gross, who led the study.  “The study results and associated probability maps provide water-resource managers and health officials with useful data as they consider management actions in areas where groundwater is most likely to contain elevated levels of arsenic.”

The Pennsylvania Department of Health plans to use the maps as an educational tool to inform health professionals and citizens of the Commonwealth about the possibility of elevated arsenic in drinking water wells and to help improve the health of residents, particularly in rural communities.  Please consider forward you certified testing data to the Citizens Groundwater Database.

Private well owners can find testing and other information on Pennsylvania Department of Environmental Protection Arsenic in Drinking Water website.

    Yesterday, while I was at work, my sister stole my apple ipad and tested to see if it can survive a forty foot drop, just
    so she can be a youtube sensation. My apple ipad is now broken and she has 83 views.
    I know this is totally off topic but I had to share
    it with someone!
