Check wells for water safety, peace of mind

"Well contamination may be widespread in state" was the headline of a New Canaan News July 27 piece.

It pointed out that private wells in Stamford, New Canaan and nearby towns may contain dangerous insecticides. You can read the article at

If you have town water you can ignore this -- I trust that town water is good and is regularly tested.

We read the piece and had our well water tested by John Voorhies at Environmental Analysis Corporation. The test, including analysis for the two pesticides, cost $330. It also analyzes for minerals, bacteria and salt level, and gives you test levels and desirable ranges for each. Our results indicated that we have Dieldrin above the "actionable level," the level at which Connecticut's Department of Public Health recommends remedial action. Our water tested Dieldrin at 0.036 micrograms/liter, and the actionable level is 0.030 micrograms/liter. Dieldrin is an insecticide, extremely persistent, banned since the mid-1970s, that was used to kill termites. It has been associated with various cancers and with Parkinson's disease.

Sharee Rusnak, epidemiologist for the Connecticut Department of Public Health is quoted in the News piece saying "if you have Dieldrin or Chlordane contamination (any amount), please get a whole house filter." We had Associated Water Industries in Stamford install today a granular activated carbon filter to remove the Dieldrin from our water. The filter cost $1,600. The water tastes the same as it did -- good -- and we feel better about drinking it and showering in it.

I write this because I care about my friends and neighbors.
