Carter Water Quality
What's in Carter's water
Nitrate
Violation on record
2 EPA violations on record (most recent 2025). Nitrate enters water mainly from fertilizer runoff, septic systems, and animal waste. High levels can interfere with the blood's ability to carry oxygen, a special danger for infants. Long-term low-level exposure has also been linked to elevated cancer risk in some studies.
Uranium
Violation on record
1 EPA violation on record (most recent 2025). Uranium occurs naturally in rock and dissolves into groundwater, with extra contributions from mining in some regions. It is both a radioactive and a toxic metal; long-term exposure mainly damages the kidneys and increases cancer risk. It is widespread in Western groundwater.
Water hardness
very hard
Carter's water is very hard. Hardness isn't a health risk, but it drives scale on fixtures and water heaters, shortens appliance life, and leaves skin and hair dry.
