These are EPA's facility records, not DWR structures. Which decreed rights sit behind an intake is the next phase; nothing here is inferred.

DWR structures that name this system

Source Probable join · fetched 2026-09-09 · matched on DWR's recorded contact or an EPA intake name; verify on the dossier

79 structures on DWR's record name this system as their contact (79). A match says who DWR lists, not who owns the water: a ditch company can own the headgate while the system owns shares, and a consultant can be the contact. The dossier holds the decree.

19 more are on the map.

Compliance record

Source Register of another agency · fetched 2026-09-09 · verify at EPA ECHO ↗

EPA's summary: violations in 0 of the last 12 quarters; not a serious violator.

No health-based or open violation on the federal record for this system.

Lead and copper: the latest 90th-percentile lead result is 0.0 mg/L (sampling period ending 2025-12-31) against an action level of 0.015 mg/L; 11 results on file.

SDWIS federal reporting carries violations and lead/copper percentiles only; nitrate, disinfection by-product and PFAS sample results are not in it. Codes are EPA's (violation, contaminant, rule); the ECHO report expands them.

PFAS and lithium: EPA's UCMR 5 monitoring, 2023–2025

Source Register of another agency · fetched 2026-09-09 · verify at EPA UCMR occurrence data ↗

25 samples, 360 results, 2024-03-06 to 2024-12-16. 3 of the 29 PFAS were detected at least once; lithium was measured up to 26.7 µg/L (no federal limit).

Rows shown: every detected contaminant plus the regulated PFAS and lithium; the rest were below their reporting limits. These are UCMR monitoring samples, not compliance samples. EPA's April 2024 rule set 4.0 ng/L (0.004 µg/L) for PFOA and PFOS, the same as UCMR 5's reporting limit, so any detection of either is at or above it; the rule's compliance date and its other limits have been under revision since 2025 and are not applied here. State PFAS sampling is on CDPHE's pages ↗.
