NEW ENGLAND COASTAL BASINS NAWQA PROGRAM: SURFACE WATER STUDIES: ROUTINE FIXED-SITE NETWORK

CHEMICAL CONSTITUENTS ANALYZED for BASIC AND INTENSIVE FIXED SITES

Basic and Intensive:

Field Measurements
Laboratory Analyses
-- Major constituents
-- Nutrients
-- Suspended sediments

Intensive only: -- Volatile Organic Compounds (VOCs)
-- Pesticides

Return to the routine fixed-site network page to access data tables by site name. The VOC and Pesticide data tables contain the Chemical Abstracts Service (CAS) Registry Numbers and USGS parameter codes listed with the analyte names.
