What the records flag
Needs attention
This system buys water from FRANKLIN COUNTY WATER & SEWER, which has 3 unresolved health-based violations
Purchased water is treated by the seller before it arrives, so the seller's compliance record travels with the water it sells.

PFOS measured at 4.8 ppt — above the 4 ppt limit systems must meet by 2029
This is not a violation today. EPA's PFAS limits take effect in 2029 (an extension to 2031 has been proposed).

Lead & copper sampling
Lead: latest 90th-percentile result 0.9 ppb — below the 10 ppb action level (sampled 2025-12-31, 4 results in the 10-year window).
The 90th-percentile result means 9 out of 10 sampled homes were at or below this level. It measures the water system's corrosion control — it cannot tell you whether your own home's plumbing adds lead. Results older than 10 years, future-dated compliance periods, and physically implausible values are excluded.
PFAS testing
29 PFAS compounds tested under EPA's UCMR5 program; 1 detected.
PFOS: up to 4.8 ppt — above the 4 ppt limit systems must meet by 2029.
UCMR5 sampling (2023–2026) at entry points to the distribution system. 'Not detected' means below the reporting limit (~4 ppt for PFOA/PFOS), not zero. A result above a future MCL is not a violation today — compliance deadlines are 2029 (2031 extension proposed). These results describe treated water leaving the plant — not the river or lake this system draws from.
Where the water comes from
Surface water.
Buys water from Franklin County Water & Sewer — which has 3 unresolved health-based violations on record. Purchased water is treated by the seller, so the seller's record travels with it.
What the record doesn’t establish
Whether your home's own plumbing adds lead or copper — no dataset covers indoor pipes.

Yes — 29 PFAS compounds under EPA's UCMR5 program, with 1 detected. PFOS measured up to 4.8 ppt, above the 4 ppt limit that takes effect in 2029. Samples are taken at entry points to the distribution system — treated water, not source water.
How many people does Lake Royale S/d serve?
EPA records list about 5,890 people served in Franklin. Service-area boundaries have known errors — a water bill is the ground truth for any single address.
Records lag their agencies' refresh cycles — a recent change may not appear yet. Absence from a dataset is absence of a record, never evidence that water is clean.
