A substantial 32.0% of assessed waterways are impaired (33 of 103 water bodies) across Nottoway County's watersheds. The leading impairment causes are escherichia coli (e. coli) and dissolved oxygen. Impairment does not mean tap water is unsafe — it measures ambient waterway conditions upstream of treatment, not finished drinking water.

Monitoring Network

EPA WQP

EPA's Water Quality Portal (WQP) aggregates monitoring data from federal, state, and tribal agencies. Nottoway County has moderate coverage with 13 active monitoring sites with 1,775 recent measurements on record. Predominant monitoring categories include physical and nutrient. More monitoring sites generally indicate greater scientific attention to local water conditions — and provide the baseline data that regulators use to set future impairment listings.
