What is in the water at 70427
3 public water systems serve this ZIP code in the federal records. Everything below comes from EPA monitoring data, and everything missing is named.
CITY OF BOGALUSA WATER SYSTEM
PWSID LA1117001 · LA · serves 14,000 people · service area inferred by a model, not supplied by the state
PFAS and lithium
Sampled, nothing detected. Tested for 30 compounds under UCMR 5 with none found at or above its reporting limit. A reporting limit is the lowest concentration the method can measure, so this means “below that” rather than “zero”.
Health-based violations
11 open health-based violation(s) recorded in SDWIS and not yet returned to compliance.

Hardness
Too few readings to state a hardness. 1 station(s), 33 result(s). Below two stations and five results this page will not state a number: a median of two readings from one creek is not your water.
VARNADO WATER WORKS
PWSID LA1117006 · LA · serves 4,230 people · service area inferred by a model, not supplied by the state
PFAS and lithium
Sampled, nothing detected. Tested for 30 compounds under UCMR 5 with none found at or above its reporting limit. A reporting limit is the lowest concentration the method can measure, so this means “below that” rather than “zero”.
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
No hardness measurement. Hardness is measured at environmental monitoring stations, and none fell inside this system’s service area. That is a gap in where monitoring happens, not a finding about the water.
BOGUE-LUSA WATER WORKS DISTRICT
PWSID LA1117009 · LA
PFAS and lithium
1 compound detected at or above the reporting limit under EPA’s UCMR 5 monitoring, across 2 samples.
| Compound | Highest detected | Samples | Most recent |
|---|---|---|---|
| lithium | 13 µg/L | 2 | 6/24/2025 |
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.

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.

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.
