Town Officials Seek Consultant For Neighborhood Pollution Clean-Up

B Y K AAREN V ALENTA

Newtown officials, as part of a consent order with the State Department of

Environmental Protection, are seeking to engage the services of a consultant

to design a solution for a groundwater pollution problem affecting more than

30 homes in the Appleblossom Lane area.

The state recently awarded Newtown a $500,000 grant to be used to supply

potable water to the homes and to hire a professional environmental consulting

and design engineering firm to "study, analyze, identify and design a

solution" for the groundwater pollution problem which could affect as many as

40 homes.

On Thursday, September 28, town officials held an informational session to

explain the project to firms that may be interested in submitting proposals.

The deadline for submission of the proposals is Thursday, October 6.

Once town officials select a consulting firm and it is approved by the

commission of the State Department of Public Health and Addiction Services,

the firm will produce a detailed proposal.

The firm will be required to investigate and report in detail on the exact

area and population affected by the pollution and identify which properties

presently or potentially may not meet the requirements for potable drinking

water.

The firm also must describe water supply alternatives, associated costs and

design criteria for each alternative. A detailed engineering report also is

required which would provide a recommended alternative water supply source and

a construction schedule for this rememdy.

In the consent order issued on August 23 by the DEP, the state said that the

extent of pollution in the wells of the residences can "reasonably be expected

to create an unacceptable risk of injury to the health or safety" of persons

who drink the water or use it for bathing or cooking.

Because the state has been unable to determine the source of the pollution,

the DEP ordered the town of Newtown to act. Most of the pollution has been

caused by petrachlorethlene, a solvent used to clean industrial machines.

The problem came to light about four years ago when the septic tank on the

Dual-Lite property on Simm Lane was discovered to be contaminated. Tests of

the leaching fields and of other properties in the area also found pollution.

Many wells closest to Simm Lane showed no contamination, however, so a

hydrogeologic study is required to determine whether the Dual-Light property

or some other property was the source of the problem.

The Dual-Lite divison of General Signal Corporation took over the property in

1987. It leases the property from Insilco Corporation, formerly known as the

International Silver Company, which operated the site for many years. Last

February the state reached an agreement with Insilco for a $2 million cleanup

of the Simm Lane property as part of a multi-million dollar bankruptcy

reorganization. Insilco filed in US District Court in San Antonio, Texas, for

Chapter 11 bankruptcy protection.

Homes with water supplies that showed low levels of contamination are being

supplied with potable water for drinking and cooking but may use their well

for such activities as taking showers and washing clothes. Whole house filters

have been installed in homes where water contamination has been found to be

high. First Selectman Bob Cascella has said one solution may be to hook those

homes to the city water supply.
