a man I worked with and his wife suffered from arsenic in their well. they were chronically sick until they were tested. they ended up suing the previous owners because they did not disclose this known danger. the house was torn down and the surrounding area closed by DEC for any development.

the couple did return to health, stayed in the county, but did extensive testing of their new home's well. most well tests are for bacterial contamination only to acquire a mortgage.
