What this violation means

Nitrate contamination is most acute in agricultural regions where fertilizer and animal waste leach into groundwater. The immediate risk is to formula-fed infants under 6 months — high nitrate levels prevent their blood from carrying oxygen, causing 'blue baby syndrome.' Pregnant women should also avoid high-nitrate water.

Recommended precautions

• →Never give untreated high-nitrate water to infants — use bottled water for formula.
• →Boiling does NOT remove nitrate. Boiling concentrates it.
• →Reverse osmosis, ion exchange, or distillation are the only effective home treatments.
• →Private well owners in farming areas should test annually for nitrate.

What this violation means

Fluoride at the optimal level (~0.7 mg/L) reduces tooth decay, which is why most US utilities add it. The MCL of 4.0 mg/L exists to protect against skeletal fluorosis from naturally high-fluoride groundwater, while the EPA's secondary standard of 2.0 mg/L addresses dental fluorosis in children.

Recommended precautions

• →Reverse osmosis removes fluoride; standard carbon filters do NOT.
• →If your child uses fluoride toothpaste and drinks fluoridated water, supervise brushing to limit ingestion.
• →Bone meal supplements often contain fluoride and should be used cautiously.

What this violation means

Arsenic is a known human carcinogen that occurs naturally in groundwater across many parts of the United States, especially the Southwest and parts of New England. Long-term exposure even at low levels has been linked to bladder, lung, and skin cancer, as well as cardiovascular disease and developmental effects in children.

Recommended precautions

• →Reverse osmosis filtration removes arsenic effectively.
• →Distillation also removes arsenic — point-of-use distillers work for drinking and cooking water.
• →Boiling does NOT remove arsenic. It actually concentrates it as water evaporates.
• →If your well water has arsenic, test annually and treat at the point of entry.

What this violation means

Lead is a potent neurotoxin with no safe exposure level. In drinking water it primarily enters via corroded lead service lines, lead-soldered copper pipes, and brass fixtures. Children under 6 and pregnant women face the highest risk because lead disrupts developing nervous and skeletal systems.

Recommended precautions

• →Run cold tap water 30–120 seconds before drinking or cooking, especially after the tap has been unused for hours.
• →Never cook with hot tap water — heat increases lead leaching from pipes.
• →Use an NSF/ANSI 53 certified filter for lead removal (carbon block or reverse osmosis).
• →If you have children, get blood lead levels tested by your pediatrician.

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.
