Analysis

What to know about Maple Hill's water

Maple Hill ranks #146 out of 323 cities in Kansas for water quality, placing it mid-range in the state.

Maple Hill 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.

PFAS compounds were detected in testing, though levels remain within current EPA limits. Residents seeking extra precaution may consider an activated carbon or reverse osmosis filter.

As a small community water system, Maple Hill may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities.

Where Maple Hill's water comes from

Groundwater

Maple Hill'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 1,046 people through 2 water systems.
