The Connecticut Department of Environmental Protection (DEP), the Department of Public Health (DPH) and the city of Milford Health Department are working with the new owner of the property where the former Milford Cleaning Village was located to determine the nature and extent of groundwater contamination moving from that site to an adjoining property that is the location of an apartment complex.
The owner of that apartment complex – the Robert Treat Apartments,
A test well on the grounds of the apartment complex showed an elevated level of perchloroethylene – also known as tetrachloroethylene, PCE, and PERC – in the groundwater at that one location. The source of the PCE is believed to be the former
Additional test wells will be drilled at the Robert Treat Apartments June 3. Groundwater will then be tested to determine the dimensions of the PCE groundwater plume emanating from the former
It is expected that full test results and an analysis of them will be reported back to DEP in about four weeks.
State and local officials noted that the situation poses no threat to the safety of drinking water used by apartment residents. The Robert Treat Apartments are on a public water system operated by the South Central Connecticut Regional Water Authority. Drinking water for the units comes from a source far from the groundwater beneath the apartments and this water is tested regularly to make certain it meets health standards.
Groundwater is defined as water beneath the ground surface. Based on data collected from the immediate area of the former
DPH Commissioner J. Robert Galvin, M.D., M.P.H., M.B.A., said, “At this time there is not enough data to indicate if residents are actually being exposed to any PCE. The investigation that is underway will answer the question of potential exposures and will allow health officials to determine if any health risk is present."
DEP Deputy Commissioner Amey Marrella said, “If these tests show there are elevated levels of PCE in the groundwater, it may be necessary to conduct further tests in some buildings. This would allow us to determine if vapors from the groundwater are migrating through cracks in building foundations and entering into the indoor air at levels requiring remediation. If this turned out to be the case – and it’s too early to know – steps can and will be taken to quickly and efficiently remediate the problem.”
Milford Mayor James L. Richetelli, Jr. said, “We are working closely with DEP and DPH to ensure the health and safety of our local residents at the Robert Treat Apartments. We are all committed to moving this investigation forward as quickly as possible so we can obtain the data we need to have a full understanding of the situation and to develop any remediation plan that proves necessary.”
Milford Health Director A. Dennis McBride, M.D., M.P.H., said, “Our primary focus is on the health and well being of the residents of the Robert Treat Apartments. To make certain these residents have a full understanding of the situation, we will move forward to provide them with information through the city’s website and face-to-face meetings.”
Robert Treat Associates, LLC., the manager of the apartment complex, has sent a letter to all residents informing them of the situation, the groundwater wells that will be installed and the testing that will be conducted.
Subsurface investigations were completed at the former dry cleaning property between 2005 and 2007. PCE was detected in soil and groundwater samples in concentrations that exceeded regulatory criteria. Remediation measures included the excavation of PCE-impacted soil and the installation of a vapor extraction system inside the former dry cleaning building. PCE detections in groundwater samples indicated that the plume was migrating off the former
