Of the 8,000 Greenwich households that rely on well water, only 300 submitted samples of their water for testing at the town's health laboratory. Doug Serafin, director of the Greenwich laboratory and bacteriologist Yvette Ghannam are making a push to encourage residents to submit water samples yearly for safety purposes.
"Our job is to protect [town residents'] health, and monitoring drinking water is one" way to do that, he said. There are no regulations on when homeowners should test their well water unless there are known health hazards.
Serafin said private water testing is a two-step process. "Residents must come in and get a sample bottle that [the laboratory] provides. Then, [they] collect their water and bring it back in for testing."
The lab tests for bacterial contamination, coliform bacteria, low pH, turbidity, color and odor along with many other things. "Tests for pH and bacteria can be done overnight, but things such as iron and manganese testing will take about a week," he said.
For the most part, Serafin said Greenwich's drinking water is very good and has no particular health hazards. Although, testing drinking water is a precaution many should take.
Private well water testing varies in price depending on what is being checked. A complete coliform test is $37, and the tests for iron and manganese are $26 each. Homeowners can visit the Greenwich Department of Health Laboratory in the basement of Town Hall and pick up information on water testing and a sample bottle.
