Water sampling stations new york city

We perform sampling after a dry period of forty eight hours and during various tidal cycles and seasons to ensure statistical integrity. We compare the sampling results to an established baseline set by the DEC. If sampling results are above the baseline, we aggressively pursue field investigations and surveillance of the adjacent shoreline to determine the source and cause of the contamination and implement immediate actions to abate any illegal discharges.

A worker unlocks the box, fills a bottle with water and takes the sample back to a lab to test for disease-causing bacteria. State law requires New York City to test the city water supply at least times a month for coliform bacteria, organisms that indicate fecal contamination of the water supply.

If there was a flaw in the old system, it was where the city did the testing. Fourteen Manhattan sampling stations were in restaurants, Laundromats and firehouses, where local contamination of the faucets might give a false reading. Park Passes. Technical Announcements.

Data from these stations are collected in varying frequencies to supply our cooperators, stakeholders, and the public with mission critical information.

The USGS collects groundwater data needed by Federal, State, and local agencies for planning and operating water-resources projects and regulatory programs. On Long Island and in the five boroughs of New York City the USGS operates over groundwater data-collection stations that provide long-term, accurate, and unbiased information that meets the needs of many diverse users.

Ground water is the sole source of water supply for more than 3 million people on Long Island, New York. Large-scale ground-water pumpage, installation of sanitary-and storm-sewer systems, and frequent variations in precipitation all have significant effects on regional groundwater levels and streamflow. The U. Groundwater data are the primary focus of the USGS data-collection program on Long Island and in the five boroughs of New York City; however, because most streams, ponds, and lakes in the region are hydraulically connected with the shallow groundwater system, the USGS monitors stream discharge and lake levels as part of its hydrologic-surveillance network.

Groundwater-level, lake-level, and stream-discharge data are all needed to accurately assess seasonal fluctuations and long-term trends in groundwater storage and climate change. The USGS publishes water-information reports on many topics and in many formats.

These include scientific and technical articles, reports, fact sheets, pamphlets, and posters. Our scientists and partners make these publications possible through innovative research.
