The New York State Department of Environmental Conservation (DEC) maintains a list of these sites on the registry of inactive hazardous waste disposal sites. As described in more detail below, following the initial investigation or site characterization completed at the K &amp; L Cleaners site (2469 Route 54A, Penn Yan), the site was added to the registry as a Class 2 site that presents a significant threat to public health or the environment.DEC completes site characterizations at potential sites or “P sites.” This is a temporary classification while DEC completes the site characterization. Once enough information is collected to confirm that contamination has been identified and poses a significant threat to human health and/or the environment and requires cleanup, the site is formally reclassified as a Class 2 site on the registry so the full investigation and remediation process can be completed. The purpose of the notice issued by the DEC is to let the community know that DEC completed the site characterization, is now reclassifying the site, and will begin a comprehensive site investigation.A Class 2 designation does not indicate that people are currently being exposed to contamination, but that DEC has determined that the contamination warrants active management and remediation to prevent or address potential risks. DEC takes immediate action when it becomes aware of exposures to contamination in order to eliminate unacceptable exposures. The Class 2 listing helps ensure the site receives a comprehensive investigation and cleanup.BackgroundA site characterization was completed by DEC at the site between 2025 and 2026 after an Environmental Site Assessment completed by the property owner revealed volatile organic compound (VOC) impacts in site soils and groundwater. The site characterization included the collection and laboratory analysis of soil, groundwater, indoor air, and sub-slab vapor samples. Based on this site characterization, the site has been added to the registry as a Class 2 site for the following reasons:• Chlorinated solvents and petroleum-related volatile organic compounds (VOCs) have been detected in site soil, groundwater, and sub-slab air samples at levels exceeding standards, criteria, and/or guidance (SCG) values.• From the site characterization work, it is clear that a significant source of perchloroethylene (PERC) exists beneath the building slab (evident in sub-slab air concentrations as high as 59,000 μg/m3).• Groundwater contamination is present with cis-1,2 dichloroethylene (DCE) observed at the site boundary at levels as high as 3,400 parts per billion (ppb). PFOA/PFOS impacts were detected in site groundwater as well, at levels as high as 17 parts per trillion (ppt) and 24 ppt, respectively.• Residences and an outlet to Keuka Lake are located within 250 feet from the site in the direction of groundwater flow.Next StepsDEC will complete a full remedial investigation to define the nature and extent of contamination in soil, surface water, groundwater and any other parts of the environment that may be affected, further assess potential exposure pathways, and evaluate cleanup options.Key components of the investigation work include:• Installing and sampling soil/bedrock borings to identify possible on-site sources of contamination.• Collecting soil vapor, sub-slab soil vapor and indoor air samples on and off site.• Installing and sampling groundwater wells to monitor impacts from areas of concern both on-site and off-site.DEC will keep you informed throughout the investigation and cleanup of the site.Additional information about this site can be found using DEC’s Environmental Site Remediation Database Search with site number 862010: appfactory.dec.ny.gov/DERExternalSearch/.</div></body>
