Analysis

What to know about Horatio's water

Horatio ranks #303 out of 345 cities in Arkansas for water quality, placing it among the lowest-rated in the state.

Horatio 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.

While lead levels are within EPA limits, they are above the recommended 5 ppb threshold that health organizations consider ideal. A point-of-use filter adds an extra layer of protection.

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