How healthy are the watersheds in Burlington County?

The top reported causes are PCBS IN FISH TISSUE, MERCURY IN FISH TISSUE, DDT IN FISH TISSUE. Impairment means the water body fails to meet state quality standards for at least one designated use — drinking water source, recreation, aquatic life, or fish consumption. Note: watershed impairment doesn't always translate to tap-water issues; treatment plants can remove most regulated contaminants.
How much water-quality monitoring happens in Burlington County?
EPA's Water Quality Portal records 59,974 measurements from 357 monitoring sites in Burlington County over the past five years. The most frequently measured characteristic groups are Physical, Nutrient, PFAS,Perfluorinated Alkyl Substance. Each measurement is a single sample analyzed for one characteristic (E. coli, pH, dissolved oxygen, etc.). High monitoring density means more scientific evidence behind any reported signal — it does not by itself indicate water quality.
What's happening with rivers in Burlington County right now?
Burlington County's primary USGS streamgage on the North Branch Rancocas Creek is currently reading 53.7 cubic feet per second — 32% of the long-term mean of 168.24 cfs. This is well below typical — often a signal of drought stress on source water. For genuine real-time data, visit waterdata.usgs.gov.
