Oily Sheen Contained on Schoharie Reservoir

Posted on: April 9th, 2015 by Leslie_Zucker

The NYC Department of Environmental Protection (DEP) is investigating an oily sheen that was discovered Monday afternoon near the Shandaken Tunnel Intake Chamber on the Schoharie Reservoir. Water supply operators worked to prevent the sheen from leaving the reservoir by shutting down the intake chamber and installing an absorbent boom around the intake structure. As additional precaution, DEP installed a containment boom where the tunnel discharges into Esopus Creek. The sheen has since dissipated and was no longer visible as of Tuesday morning. The source is yet to be determined through testing, but is suspected to be an undiscovered tank that washed into the Schoharie Reservoir during Hurricane Irene in 2011. The tank may have been dislodged by shifting ice and low water levels. For more information, see DEP’s complete press release and a Watershed Post article.
