POTOMAC RIVER WATER FILTRATION

New

NPDES ID: MD0051586

Aluminum is a sediment-related pollutant that indicates excessive suspended solids and metal contamination in the facility's discharge. The Potomac River and its associated coldwater and warmwater stream habitats in the Piedmont Uplands are at risk, where elevated aluminum concentrations will accumulate in sediments and bioaccumulate in aquatic organisms, degrading water quality and harming sensitive benthic communities, fish populations, and freshwater mussels that depend on clear water conditions. Continued non-compliance will impair the ecological integrity of these Piedmont stream ecosystems through smothering of substrates, reduced light penetration, altered pH and metal toxicity to aquatic life, and potential cascading effects on downstream communities including the Tidal Potomac.
