The tests results released this afternoon included data of the third set of samples taken from 61 homes this year. Test from about 14 more homes are pending.
A set of results released April 6 found traces of elevated levels of sodium, methane, arsenic, chromium, and lithium in 71 samples from 20 different wells that were at or near “action levels,” which are flags for further analysis. But to date, none of the test results, which include some water supplies that have been taken off line, have warranted immediate action in the agency’s assessment. The EPA is continuing to supply water to four homes that have previously tested positive for pollution at levels that have raised health concerns.
