Analysis

What to know about Brandon's water

Brandon ranks #92 out of 446 cities in Wisconsin for water quality, placing it above average in the state.

Brandon 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, Brandon may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities.
