Mark Cooper, health director of the Westport Weston Health District, will be joined by state epidemiologist Brian Toal to discuss the finding of arsenic in some Weston well water and throughout the state.
On March 18, the Connecticut Department of Health issued a recommendation that all private well owners in the state have their water tested for arsenic and uranium, based in part on reports from Weston home-owners who found elevated levels of arsenic in their water.
Mr. Cooper has been compiling a map showing where arsenic levels are high, low and nonexistent. He said residents may continue to send him their water tests through April 11.
Arsenic and uranium are metals that occur naturally in bedrock. When groundwater comes in contact with the bedrock, the metals may leach out and contaminate private wells.
The DPH warns that both metals are considered toxic and can have a variety of adverse health effects if people are exposed at high enough levels and for a long period of time.
