There was little peace on Pease Road after homeowners opened letters from a water testing company alerting them to the possibility that their wells might be contaminated with arsenic.

The letter, sent by West Haven water testing company Aqua MD Water, warned that a local well had tested for high levels of arsenic and that continued exposure to the poison has been linked to cancer.

Some residents reacted to the warning with skepticism. Judy DeFransca said she believes the company might have something to gain. And Pease Road resident Ken Johnson says he laughed when he got the letter. Johnson?s own water testing company has only found that the local wells he tested have high levels of pH.

Aqua MD Water managers say they had no intention of scaring people. After they found the contaminated well they contacted the health department.

Both Aqua MD and health department officials say homeowners who use well water for drinking should test their water at least once a year.
