Analysis

What to know about Madison's water

Madison ranks #206 out of 230 cities in Virginia for water quality, placing it among the lowest-rated in the state.

The city draws from surface water sources, which are more susceptible to seasonal runoff and agricultural contamination, requiring extensive multi-barrier treatment including coagulation, filtration, and disinfection.

Haloacetic acid (HAA5) levels were elevated at 44.8 µg/L in UCMR 4 testing, though below the 60 µg/L EPA limit. Activated carbon filtration can help reduce these disinfection byproducts.

Hexavalent chromium (chromium-6) was detected at 0.05 µg/L in UCMR 3 testing. While below California's 10 µg/L limit and with no federal MCL set, residents sensitive to this contaminant may consider reverse osmosis filtration.

The system has seen 12 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.
