What is in the water at 88324
2 public water systems serve this ZIP code in the federal records. Everything below comes from EPA monitoring data, and everything missing is named.
CDS RAINMAKERS UTIL LLC RANCHO RUIDOSO
PWSID NM3521014 · NM · serves 839 people
PFAS and lithium
Not sampled for PFAS. EPA’s UCMR 5 monitoring covered every system serving more than 3,300 people and only a sample of smaller ones. This system was not in it, so there is no result to show, which is not the same as a result showing nothing.
Health-based violations
No open health-based violation on record. This covers MCL, treatment technique and MRDL violations in SDWIS that have not been returned to compliance. It excludes monitoring and reporting violations, which are the large majority nationally, so this is not “no violations”, and SDWIS completeness varies by state.
Hardness
Median hardness 754 mg/L as CaCO₃, measured at 4 stations serving this system across 7 results, 2015-04-17 to 2019-03-09. Measured in the water source and distribution area, not at a tap, and not in your home.
RUIDOSO WATER SYSTEM
PWSID NM3513114 · NM · serves 15,947 people
PFAS and lithium
2 compounds detected at or above the reporting limit under EPA’s UCMR 5 monitoring, across 10 samples.
| Compound | Highest detected | Samples | Most recent |
|---|---|---|---|
| lithium | 23 µg/L | 9 | 8/9/2023 |
| PFBA | 0.0054 µg/L | 1 | 8/20/2024 |
A detection is a measurement, not a violation and not a health finding. EPA states that UCMR 5 results do not indicate compliance or non-compliance with any limit.
Health-based violations
No open health-based violation on record. This covers MCL, treatment technique and MRDL violations in SDWIS that have not been returned to compliance. It excludes monitoring and reporting violations, which are the large majority nationally, so this is not “no violations”, and SDWIS completeness varies by state.
Hardness
Median hardness 357 mg/L as CaCO₃, measured at 5 stations serving this system across 9 results, 2017-10-15 to 2024-09-18. Measured in the water source and distribution area, not at a tap, and not in your home.
What this report cannot tell you
Every figure describes water at a sampling point: a treatment plant, an entry point to the distribution system, or a monitoring station. None of it describes water arriving at your tap. Plumbing between the two can add lead and copper, and if your home was built before 1986 a test kit tells you something no federal dataset can.
