Patterson Tract Csd
No action needed
Minor violations on record, all resolved
Health-based violations occurred in the past but have since been resolved. The system is currently compliant.
Should I be concerned?
No. Historic violations are common in water systems of all sizes. What matters is whether they are resolved — these are.
No action needed
No PFAS detected in this water system
PFAS was monitored under EPA's UCMR5 program (2023–2025) and not detected.
Should I be concerned?
No. This contaminant is monitored and not detected.
No action needed
Not detected in this water system
Chromium-6 is the contaminant from the Erin Brockovich case — it's not present in detectable amounts here.
Should I be concerned?
No. This contaminant is monitored and not detected.
Lithium not detected in this system
Not detected in this water system
Lithium occurs naturally in some groundwater sources at low levels. It is the same element used in psychiatric medication, but even elevated drinking water concentrations are thousands of times below a therapeutic dose.
Why is lithium even tested for?
EPA included lithium in its Unregulated Contaminant Monitoring Rule (UCMR5) to gather national data. There is currently no federal limit for lithium in drinking water. Monitoring it helps researchers and regulators understand where it occurs and at what levels.
Check your home's pipes
Lead risk depends on your home, not just the water system
The concern isn't usually the treatment plant — it's pipes inside older homes. No level is considered safe for children under 6.
Should I be worried?
Not necessarily — but if your home was built before 1986, it's worth checking whether you have lead pipes or solder. Run cold water 30 seconds before drinking in the morning.
