Analysis

What to know about Arkansas City's water

Arkansas City ranks #280 out of 323 cities in Kansas for water quality, placing it among the lowest-rated in the state.

Arkansas City 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 0.12 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 22 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.

Where Arkansas City's water comes from

Groundwater

Arkansas City'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 17,878 people through 5 water systems.

What contaminants are in Arkansas City's water?

Lead was measured at 0.0 ppb (90th percentile). 3 PFAS compounds were detected. 80 violations are on record.

How is Arkansas City'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 Arkansas City?

PFAS compounds exceed EPA limits — a reverse osmosis or activated carbon filter is recommended.

Where does Arkansas City's water come from?

Arkansas City's water is sourced from Groundwater. The city has 5 water systems serving approximately 17,878 residents.

What health violations has Arkansas City's water system had?

Arkansas City has 7 health-based violations on record. The most recent violation was recorded in April 2025. Health-based violations mean the water exceeded EPA maximum contaminant levels (MCLs) for a regulated substance. 22 violations remain unresolved.

Is Arkansas City's groundwater at risk of contamination?

Arkansas City 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 80 violations on record that may relate to groundwater quality.
