What this violation means

The EPA regulates total chromium, which includes both trivalent (Cr-3, an essential nutrient) and hexavalent (Cr-6, the carcinogen made famous by the Erin Brockovich case). California has set a separate Cr-6 MCL of 10 ppb; the federal standard does not yet distinguish the two.

Recommended precautions

→Reverse osmosis effectively removes chromium.
→Some specialized ion exchange resins target hexavalent chromium specifically.
→Standard carbon filters do not reliably remove chromium.

What this violation means

Total Trihalomethanes (TTHMs) form when chlorine reacts with naturally occurring organic matter — leaves, soil, algae — in source water. They are among the most commonly reported violations because utilities pulling from surface water (rivers, lakes, reservoirs) struggle to balance disinfection with byproduct formation. Long-term exposure has been linked to bladder cancer and adverse pregnancy outcomes.

Recommended precautions

→Activated carbon filters (pitcher, faucet, or under-sink) effectively reduce TTHMs.
→Letting water sit uncovered allows TTHMs to off-gas — leave a pitcher in the fridge for several hours.
→Shower with the bathroom fan on; TTHMs can volatilize into the air during hot showers.
→Boiling reduces TTHMs through volatilization, but only after extended boiling.
