The top reported causes are MERCURY IN FISH TISSUE, DISSOLVED OXYGEN, CHLOROPHYLL-A. 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 Broward County?
EPA's Water Quality Portal records 92,929 measurements from 261 monitoring sites in Broward County over the past five years. The most frequently measured characteristic groups are Physical, Nutrient, Organics, Pesticide. 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 Broward County right now?
Broward County's primary USGS streamgage on the L-28 CANAL ABOVE S-140 is currently reading 44.6 cubic feet per second — 50% of the long-term mean of 88.5 cfs. This is well below typical — often a signal of drought stress on source water. For genuine real-time data, visit waterdata.usgs.gov.
