The quarterly sampling is to keep in compliance with the discharges for several bridge and tunnel sites operated by NYCDOT. The sampling is quarterly for each location, with the proper collection of water samples from sump areas prior to discharge for Oil and Grease, Total Suspended Solids, pH, temperature and discharge volume calculations.
EnviroMed uses proper sampling procedures following EPA, ASTM, and State of New York, and New York City DEP requirements. The sampling is performed throughout Queens, Bronx, Brooklyn, and Manhattan boroughs. The samples are delivered same day as collection to a state of New York certified laboratory. Each sampling site has a report prepared by EnviroMed and submitted to NYCDOT for the SPDES permit program.
