Old Lyme — Two wells serving office buildings are among 14 water systems statewide showing high levels of lead in the most recent tests, according to the state Department of Public Health.

The wells serve the state Department of Energy and Environmental Protection’s Marine Headquarters on Ferry Road, and the Eastport West 2 office complex off Hatchetts Hill Road.

About 50 people work in the DEEP building, and about 30 work in the 24,098-square-foot office building, according to the health department.

The 14 water systems with high lead levels are among 1,058 statewide tested under the federal Safe Drinking Water Act and its Lead and Copper Rule, with 99 percent achieving compliance, according to the health department.

The largest of the systems with high lead serves about 514 students and staff at Parkway School in Greenwich.

The two Old Lyme systems are the only ones of the 14 in New London County.

The health department released the information about the lead testing earlier this month in response to concerns raised by the crisis in Flint, Mich., over high lead levels in water there.

John Sieviec, sanitarian for Old Lyme, said he is aware of the findings about the two systems and that actions are being taken to correct the problems.

Workers at both buildings have been provided with bottled water and told not to use the tap water.

No food service establishments or medical offices are located in the Eastport West 2 building, he said.

Lori Mathieu, chief of the drinking water section of the public health department, said Wednesday that DEEP is required to submit a proposal for corrosion control treatment.

Actions to control corrosion would prevent lead from leaching out of pipes and other equipment into the water system.

Eastport West 2 owners have submitted a proposal for corrosion control that is being reviewed by the health department, she said.

Results show one of five tests conducted in December on samples from Eastport West 2 had lead levels exceeding the Environmental Protection Agency’s Action Level of 15 parts per billion.

That sample had 37 parts per billion, while the other four tests had levels of 1 or 2 parts per billion.

Two of five tests done in June on samples from the DEEP well had levels above 15 parts per billion.

One test yielded 16 parts per billion, and the other had a level of 289 parts per billion.

The other three tests showed levels of 2, 10 and 11 parts per billion.

Lead is a neurotoxin that can cause a variety of health effects, especially in children.

Sieviec said he was not aware of any illnesses caused by the lead levels in the two wells.

Dennis Schain, spokesman for DEEP, said agency staff have not been using tap water in the building for several years because of high concentrations of chloride and sodium in the water.

The well is located near the Connecticut River and Long Island Sound, where groundwater mixes with brackish water that is corrosive and causes lead to be leached from certain taps, Schain said.

The agency on Tuesday submitted a proposed solution to the state health department, which “could involve an off-site well,” Schain said.

The marine headquarters building was constructed in the early 1990s, he added.

The owner of Eastport West 2, built in 1988, could not be reached for comment.
