Analysis

What to know about Edgar's water

Edgar ranks #237 out of 446 cities in Wisconsin for water quality, placing it below average in the state.

Edgar 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.

Hexavalent chromium (chromium-6) was detected at 0.07 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.

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