Madhar Petroleum standing, high SDWIS violation third
24% of 161 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 24% is upper-third health share (> 23%). Population rank #26,095 of 29,740 among systems serving 500+.
The verdict
Madhar Petroleum sits in the upper third of the sitemap cohort by violation count (161), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is smaller (602; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 24% - most of this ledger is MCL or treatment-technique exceedance. No UCMR5 PFAS test appears for this system in this extract.
