What's in White Tanks's water
Arsenic
Violation on record
1 EPA violation on record (most recent 2024). Arsenic is a naturally occurring element that dissolves into groundwater from rock and is also released by mining and industry. Long-term exposure is associated with several cancers and with skin, cardiovascular, and developmental harm. It is common in parts of the Southwest.
Total Trihalomethanes (TTHM)
Violation on record
1 EPA violation on record (most recent 2025). TTHM form when chlorine used to disinfect water reacts with natural organic matter. Long-term exposure has been linked to increased cancer risk and to harm in pregnancy. Levels often rise in warmer months and in systems with more organic material.
Nitrate
Violation on record
1 EPA violation on record (most recent 2022). 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.
PFAS (forever chemicals)
Detected
Detected in the supply below the federal limit. PFAS are "forever chemicals" that don't break down and accumulate over time. Compounds found: PFBA.
Water hardness
very hard
White Tanks'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.
