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.
