Sunnyside Gardens Public Water Line Extension Update - October 2017

Field work associated with the Interim Remedial Measure ("IRM") was completed in 2016 involving the installation of a public water supply line extension to ensure the residents of the Sunnyside Gardens neighborhood in the Town of Glenville have clean, safe drinking water. The NYS Department of Environmental Conservation ("DEC") funded and conducted the IRM. An IRM is a discrete set of planned actions for both emergency and non-emergency situations that can be conducted without the extensive investigation and evaluation of a Remedial Investigation/Feasibility Study. Documents related to the IRM and cleanup of this site can be found at the location(s) identified below under "Where to Find Information." The site is listed as a Class "2" site in the State Registry of Inactive Hazardous Waste Sites (list of State Superfund ("SSF") sites). A Class 2 site represents a significant threat to public health or the environment; action is required.

Highlights of the Completed Interim Remedial Measure

Extending and connecting to the existing public water line was performed as an IRM to readily address groundwater contamination originating from the site located at 107 Freemans Bridge Road, Glenville, Schenectady County.

The DEC, under the SSF program, provides relief to homeowners when their private wells become threatened or impacted by contamination from hazardous wastes. Analytical data generated from the sampling of the groundwater in the area has detected volatile organic compounds ("VOCs") above the maximum contaminant levels as established by the New York State Department of Health ("DOH"). Consequently, it has been determined that the existing private potable water supply wells in the area are being threatened or already have been impacted by VOCs and are no longer able to safely provide potable water without proper treatment.

The IRM for this site involved the installation of and connection to a new water line extension from an existing water main on Freemans Bridge Road. Work areas generally consisted of property along Old Sunnyside Road, and Sunnyside Gardens (Arbor Lane, Greenway Drive, Havenbrook Drive, Westwood Lane). There were 100 residents identified within the water line extension area, all of whom were connected to the water line in 2016. At the same time all of their private water supply wells were de-energized, and the lines cut and capped.

During Fall 2015, the DEC's water line contractor installed 2,800 feet of 12-inch water main along Sunnyside Road and 4,080 feet of 8-inch water line throughout the Sunnyside Gardens Neighborhood. The water mains were pressurized and disinfected prior to winter shutdown in February 2016. The water lines are now currently active and provide fire service to your area.

In Spring 2017, the contractor returned to the project area to complete warranty work and to correct any restoration work deficiencies identified in late Fall 2016. The contract warranty period expired in August 2017. Therefore, no further corrective measures will be completed by the DEC now that the construction contract has been officially closed and the warranty period has expired. The DEC has prepared a Construction Completion Report ("CCR"). The CCR states that cleanup requirements have been achieved to fully protect public health and the environment for the proposed site use.

Next Steps

Once both operable units (OU) of this site have been cleaned up, DEC will reclassify or delist the site from the Registry of Inactive Hazardous Waste Disposal Sites. The DEC will continue to keep the public informed throughout the cleanup. The approved CCR has been made available to the public (see "Where to Find Information" below).

Background

Location: The Former Kenco Chemical Company Site is located at 107 Freemans Bridge Road, in a primarily commercial area, with adjacent farmland and some residential properties nearby. The Site is approximately 0.86 acres in size.

Site Features: The main site features include several concrete foundations for former buildings and an underground storage tank. An unnamed creek with associated wetlands exists between the site and railroad tracks. A large warehouse building was demolished and removed from the site in 2016.

Current Zoning and Land Use: The site is a commercially zoned property, with mixed commercial and residential use in the area. The on-site storage/warehouse buildings were removed in 2015 and 2016, leaving the foundation slabs. The site is locally zoned General Business and the surrounding area is locally zoned General Business and Research/Development/Technology.

Past Use of the Site: The site was used for chemical distribution and warehousing by Kenco Chemical Company Inc. and Voelker Sales Inc. until approximately 1999. The chemicals handled on-site included swimming pool chemicals and dry cleaner chemicals (tetrachloroethene, a.k.a. perc or PCE). The site was purchased by Ultimate, LLC in 1999, and the property was used for general storage and warehousing until the on-site buildings were demolished in 2015 and 2016. A pre-sale site assessment for a nearby parcel identified contamination adjacent to the Former Kenco parcel, resulting in further investigation of the site.

Site Geology and Hydrogeology: The groundwater flows generally south and southeast from the Site, and contamination is further transported by impacted creeks. Depth to water ranges from 3-15 feet below ground surface. Depth to Bedrock is generally 27-40 feet below ground surface. Soils consist primarily of silt, sands and clayey layers, with two or more sandy zones divided by clays in many areas across the neighborhood.
