Long Lake WD standing, high SDWIS violation third
800 people served (SDWIS) - smaller served population (≤ 999). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 5% is middle-third health share (≤ 23%). Population rank #22,593 of 29,740 among systems serving 500+.
The verdict
Long Lake WD sits in the upper third of the sitemap cohort by violation count (122), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is smaller (800; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 5% (middle-third health share (≤ 23%)). No UCMR5 PFAS test appears for this system in this extract.

How many violations vs. how serious, among peer systems
Long Lake WD plotted against 29 peer public water systems (500+ people served), by total violation count (x) and the share of those violations that are health-based (y). The crosshair sits at this sample's own median on each axis. A high violation count does not automatically mean a serious record: most monitoring and reporting violations are minor, not health-based.
