Its water is drawn from groundwater sources. EPA's Safe Drinking Water Information System records 24 total violations for this system , of which 2 (8%) are health-based — meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 20 monitoring and reporting violations are on file. The most recent violation on record dates to 2011.

The most frequently cited contaminant at this system is Coliform (TCR), recorded in 17 violations (MR). Under EPA's UCMR5 PFAS monitoring program, 1 PFAS compound was detected in samples collected from this system, with a maximum reported concentration of 169 ppt. PFAS are persistent synthetic chemicals linked to health effects at very low exposure levels.

Across 09, EPA tracks 323 public water systems serving 555,721 people, with 48,296 cumulative violations and 3,354 health-based violations on record. About 97% of systems in the state carry at least one violation, and state-wide the average per system is 149.5 violations. Lone Butte Industrial's 24 violations sit below the 09 average.
