waterverge.com Parks, LA — Water Quality Report
Parks's drinking water received a grade of C (60.9 out of 100), indicating fair water quality. The city's 1 water system serves approximately 12,801 residents using groundwater.
Lead levels were measured at 2.0 ppb (90th percentile), well within EPA limits. UCMR 5 testing detected 5 PFAS compounds, with levels exceeding EPA maximum contaminant levels in the water supply.
The system has 36 violations on record, including 15 health-based violations. 20 remain unresolved.
What to know about Parks's water
Parks ranks #176 out of 309 cities in Louisiana for water quality, placing it below average in the state.
Parks relies on groundwater, which is generally less vulnerable to surface contamination but can be affected by naturally occurring minerals like arsenic and nitrate, as well as agricultural and industrial runoff.
Of particular concern: PFAS "forever chemical" levels exceed the 2024 EPA maximum contaminant levels. These synthetic compounds don't break down naturally and require specialized filtration such as reverse osmosis or granular activated carbon.
Hexavalent chromium (chromium-6) was detected at 0.03 µg/L in UCMR 3 testing. While below California's 10 µg/L limit and with no federal MCL set, residents sensitive to this contaminant may consider reverse osmosis filtration.
The system has seen 10 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.

Water source & infrastructure
Where Parks's water comes from
Parks's drinking water is drawn from underground aquifers through wells.
Groundwater is naturally filtered through rock and soil layers, generally requiring less treatment than surface water. However, it can contain naturally occurring contaminants like arsenic, radon, and minerals.
Agricultural activity, septic systems, and industrial operations near well fields can introduce nitrates, pesticides, and volatile organic compounds.
The system is operated by local government ownership and serves approximately 12,801 people through 1 water system.
Water bodies near Parks
Parks is located near 5 notable water bodies. These water bodies contribute to the regional watershed and may indirectly affect groundwater quality.

Is Parks, LA tap water safe to drink?
Parks's water quality earned a grade of C (60.9/100). Some concerns have been identified. Consider a water filter for an extra layer of protection. The city ranks #176 out of 309 cities tested in Louisiana.
What contaminants are in Parks's water?
Lead was measured at 2.0 ppb (90th percentile). 5 PFAS compounds were detected. 36 violations are on record.
How is Parks's water quality grade calculated?
The grade is based on four factors: violation history (40%), lead and copper levels (25%), PFAS contamination (25%), and regulatory compliance (10%). The score is also adjusted based on how complete the available data is. See our methodology page for full details.
Do I need a water filter in Parks?
PFAS compounds exceed EPA limits — a reverse osmosis or activated carbon filter is recommended.
Where does Parks's water come from?
Parks's water is sourced from Groundwater. The city has 1 water system serving approximately 12,801 residents.
What health violations has Parks's water system had?
Parks has 15 health-based violations on record. The most recent violation was recorded in October 2025. Health-based violations mean the water exceeded EPA maximum contaminant levels (MCLs) for a regulated substance. 20 violations remain unresolved.
Is Parks's groundwater at risk of contamination?
Parks uses groundwater, which can be affected by naturally occurring contaminants like arsenic, radon, and nitrate, as well as agricultural runoff and industrial activity. The system has 36 violations on record that may relate to groundwater quality. Groundwater systems are generally less susceptible to surface contamination but should be monitored for emerging contaminants like PFAS.
Why does Parks have so many PFAS compounds in its water?
5 different PFAS "forever chemical" compounds were detected in Parks's water supply during UCMR 5 testing. PFAS contamination often originates from proximity to military installations (AFFF firefighting foam), airports, industrial manufacturing sites, or wastewater treatment facilities. Some levels exceed the 2024 EPA maximum contaminant levels — a reverse osmosis or NSF-certified activated carbon filter is strongly recommended.
How does Parks's water compare to other cities?
Parks ranks #176 out of 309 cities in Louisiana (better than 43% of state cities) and #12035 out of 15744 cities nationally (24th percentile). The grade of C reflects the combined assessment of violation history, lead and copper levels, PFAS contamination, and regulatory compliance.
