Analysis

What to know about Jefferson's water

Jefferson ranks #280 out of 378 cities in Georgia for water quality, placing it below average 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 31.6 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 0.16 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 8 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.
