A detailed environmental study on the site of the former Doro Dry Cleaners at 3460-3466 Genesee St. will be launched by the state Department of Environmental Conservation, the agency announced this week.

The site, which is listed as a “Class 2” site in the state’s Registry of Inactive Hazardous Waste Sites, represents “a significant threat of public health or the environment” requiring action, according to the DEC.

The site, which is commercially zoned but currently not in use, was utilized for dry cleaning for about 40 years. The site was apparently contaminated by some of those uses including the storage and use of “chlorinated solvent” by the dry cleaning business, the DEC reported.

Past site investigations revealed that the groundwater there was contaminated with tetrachloroethene, a commonly-used dry cleaning solvent, DEC reports stated.

The investigation will be performed by the DEC and assess conditions on the site. Goals of the study will be to establish the type and extent contamination to the soil, surface and groundwater along with other parts of the environment that were affected as well as the source or sources of contamination.

The DEC pointed out that the study will also aim to assess the impact of the contamination on the public health and environment and provide details toward remedying the contamination.

Surrounding properties are still being used for both residential and commercial purposes.

DEC officials reported that the information collected from this investigation will be “summarized in a Remedial Investigation report” expected to be available sometime in 2013.
