Sunstone Bear Creek

Monitoring and Reporting: 6 violations, May 2025 to Mar 2026. The system did not complete required monitoring, or did not report the results on time. This does not show that a contaminant was found.

Contaminant on the record: Interim Enhanced Surface Water Treatment Rule.

Treatment Technique Violation, health-based: 1 violation, Jan 2024 to Mar 2024. The system did not carry out a required treatment process or corrective action.

Monitoring and Reporting: 15 violations, May 2025 to Mar 2026. The system did not complete required monitoring, or did not report the results on time. This does not show that a contaminant was found.

What the rule requires: All systems using surface water (rivers, lakes, reservoirs) or groundwater under surface influence (GWUDI) must filter and disinfect. Treatment technique violations mean the system failed to maintain adequate disinfectant residual, exceeded turbidity limits, or lacked required permits. Snowmelt and storm events can raise turbidity and pathogen loads in surface water.

Health effects: Without proper filtration/disinfection: Giardia lamblia (severe diarrhea, cramping), Cryptosporidium (life-threatening for immunocompromised individuals), viruses (hepatitis A, norovirus). Turbidity itself is not a health risk but can shield pathogens from disinfection. Limit: Treatment technique: turbidity ≤0.3 NTU in 95% of monthly samples; detectable disinfectant residual in 95% of distribution samples

Monitoring and Reporting: 2 violations, Jan 2024 to Jul 2025. The system did not complete required monitoring, or did not report the results on time. This does not show that a contaminant was found.

Contaminants on the record: Total Haloacetic Acids (HAA5), TTHM (Total Trihalomethanes).

Monitoring and Reporting: 21 violations, Jan 2024 to May 2025. The system did not complete required monitoring, or did not report the results on time. This does not show that a contaminant was found.

Contaminants on the record: 1,2,4-Trichlorobenzene, cis-1,2-Dichloroethylene, Xylenes, Total, Dichloromethane (Methylene Chloride), o-Dichlorobenzene, p-Dichlorobenzene, Vinyl Chloride, 1,1-Dichloroethylene, trans-1,2-Dichloroethylene, 1,2-Dichloroethane, 1,1,1-Trichloroethane, Carbon Tetrachloride, 1,2-Dichloropropane, Trichloroethylene (TCE), 1,1,2-Trichloroethane, Tetrachloroethylene (PCE), Chlorobenzene, Benzene, Toluene, Ethylbenzene, Styrene.

Other Violation: 1 violation, Oct 2024 to Nov 2024. A requirement other than monitoring, reporting, or a contaminant limit, such as public notice or the annual water quality report.

What the rule requires: Community water systems must deliver an annual water quality report (Consumer Confidence Report) to all customers by July 1, covering the previous year. It must list all detected contaminants, compare them to MCLs, identify source water, and include educational language about lead. A violation means the report was not delivered on time or was incomplete.
