Analysis

What to know about Ceresco's water

Ceresco ranks #174 out of 200 cities in Nebraska for water quality, placing it among the lowest-rated in the state.

Ceresco 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.

Lead levels exceed the EPA action level of 15 ppb, which typically indicates aging lead service lines or lead solder in the distribution system. An NSF 53-certified filter is strongly recommended for drinking and cooking water.

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