Discounted Radon Testing Available In Greenwich

GREENWICH, CT — The month of January has been designated as Radon Action Month by the United States Environmental Protection Agency (U.S. EPA), and discounted radon testing for both well water and air is available in Greenwich from now through February.

Radon is the second leading cause of lung cancer in the U.S. after smoking, and it is the leading cause of lung cancer among non-smokers, the Greenwich Department of Health said in a news release, noting that radon is estimated to be responsible for more than 21,000 deaths from lung cancer in the US each year.

About 2,900 of these deaths occur among people who have never smoked, the health department said. Smokers exposed to radon have a much higher risk for developing lung cancer than smokers who are not exposed.

Radon is a naturally occurring, invisible, odorless, radioactive gas that is normally harmlessly dispersed in outdoor air but can reach harmful levels when it enters and gets trapped in buildings, particularly in the winter months when homes and other buildings are closed up.

Radon comes from the ground and can enter a home through small cracks and other openings in the foundation. Dissolved radon can occur naturally in groundwater and may be aerosolized into the air within a home serviced by well water when running faucets, showers, dishwashers or a washing machine.

The discounted air/well water testing in Greenwich is made possible in part by a state grant.

"We are pleased to offer a complete radon testing program to Greenwich residents. This program demonstrates the department’s commitment to protect residents from a serious public health hazard. All residents are encouraged to test their homes for radon in both well water and air this winter. Testing homes for elevated levels of radon is simple and inexpensive even when the reduced-fee testing program is no longer available," said Greenwich Director of Health Caroline Calderone Baisley in a news release.

Director of the Division of Environmental Services Laboratory Michael Long said people tend to downplay radon and its health effects because you can't see or smell it.

"Over ten years of radon testing, half of the homes tested in Greenwich had a radon in air level above the EPA action limit of 4.0 pCi/L," Long said. "Radon, if discovered, can be remediated by qualified contractors inexpensively. The addition of testing well water for radon adds one more important diagnostic tool to identify another potential source of radon being released into the air."

To take advantage of Greenwich's reduced fee radon testing program, call the Greenwich Department of Health Laboratory at 203-622-7843 for details.

Radon testing kits for air and well water may be obtained from the department’s laboratory located on the ground floor of town hall during laboratory hours, Monday through Friday from 8 a.m., to 3 p.m.. A reduced fee of $42 will be charged for radon in-air testing, down from a regular fee of $67 per test.

Radon in-air testing should be done in the home the same day and the kit returned to the lab four days later, with results being reported by email or regular mail. A reduced fee of $49 will be charged for radon testing of well water, compared with a regular fee of $77. Customers will be notified of their results within a week of returning samples to the lab.

The town noted that households will be limited to one reduced fee air test per household per visit. Customers with elevated radon levels in air and/or well water will be referred to a list of state certified radon mitigation companies.

Radon is present at elevated levels in about one of every five Connecticut homes, the town said. If radon is already present at elevated levels in the air, the addition of the aerosolized radon from a faucet could cause the radon action level in the home to be exceeded. Distribution water (town water) from Aquarion does not contain radon.

The EPA recommends radon abatement measures to be undertaken if radon in air levels exceed 4.0 picocuries per liter (pCi/L). Even if the radon test level is below the action level of 4.0 pCi/L, homeowners should consider testing again sometime in the future as radon levels can fluctuate.

Retesting is particularly important if construction work has been done, since it may have disturbed the soil around the home or created cracks in the foundation which could provide an entry point for radon, the town said. For radon in well water, Connecticut has set an action level of 5,000 pCi/L and recommends that all wells be tested for radon at least once, and ideally every five years.
