Julia Reischel in the Watershed Post reports an “oily sheen” of "motor oil or hydraulic oil" was found on the surface of the Schoharie Reservoir April 6. The New York City Department of Environmental Protection reports none of the oil appears to have entered the city's drinking supply, and that the Shandaken Tunnel was reopened April 9. Reportedly, the sheen was not seen April 7, but three layers of boom remain at the tunnel intake, and two layers of boom are at the tunnel outlet alongside the Esopus Creek. The DEP will continue sampling the water through at least April 14. Read the full story in the Watershed Post.
