Suffolk County and New York State recognize the pressing need to address significant nitrogen levels in our local waterways and groundwater caused in part by underground septic tanks. On this episode of Water Matters, Marshall Brown talks with Peter Scully, sewer czar of Suffolk County, on the issue of septic tanks on Long Island, the damage they do to our creeks and bay, and what the County is doing over the coming years to replace over 200,000 septics with sewering and on site sewering replacements. It’s an enormous task but one which we must take on.
