Analysis

What to know about Mcincr, Mcb Quantico's water

Mcincr, Mcb Quantico ranks #195 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.

Of particular concern: PFAS "forever chemical" levels exceed the 2024 EPA maximum contaminant levels. These synthetic compounds don't break down naturally and require specialized filtration such as reverse osmosis or granular activated carbon.

Disinfection byproduct (HAA5) levels exceeded the EPA's 60 µg/L maximum contaminant level in UCMR 4 testing (2018–2020). These compounds form when chlorine reacts with natural organic matter and have been linked to increased cancer risk with long-term exposure.

Hexavalent chromium (chromium-6) was detected at 0.10 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.
