Waukesha Drinking Water Quality

Water safety is a non-trivial matter, but it tends to get a little geeky.

There are a lot of compounds in water. There is a great non-profit that compiles this data. It’s Environmental Work Group and their database is impressive.

For the Waukesha Water Utility, the full report is here.

Contaminants In Waukesha Drinking Water

The contaminants in Waukesha Drinking Water break into three broad groups.

Problem Group #1: Radium and Radioactive Material


  • Combined Radium (-226 & -228)
  • Radium-228
  • Radium-226
  • Alpha particle activity
  • Gross beta particle activity
  • Thallium
  • Combined Uranium

Solution:  Radium has received a lot of the press coverage for Waukesha’s water diversion.  Eight of the 18 water contaminants are radioactive.  Yes, that sounds bad.

The solution is pretty easy.  A functioning water softener actually removes things like radium before calcium.

Let me repeat that: If you have a functioning water softener, you do not have a radium problem.

Problem Group #2:  Disinfection Byproducts


  • Total haloacetic acids (HAAs)
  • Monochloroacetic acid
  • Bromodichloromethane
  • Dibromochloromethane
  • Bromoform
  • Dichloroacetic acid
  • Dichloromethane (methylene chloride)


Seven more of our 18 contaminants are actually there on purpose. Cities chlorinate water to reduce contamination during transportation. As chlorine contacts organic matter, the reaction creates disinfection byproducts (DBP’s).

While most DBP’s are known carcinogens, it’s kind of central to our water safety policy. In general, the slow risk of carcinogens is better than the fast risk of e coli.

Significant to total elimination of these problems is possible. Carbon and/or reverse osmosis will reduce these to non-detectable amounts.

Problem Group #3:  The Leftovers


  • Radon
  • Arsenic
  • Lead


We’re down to 3 of the 18 original contaminants.

The whole-house carbon dechlorinator recommend to remove those DBP’s from above will adsorb radon.

Arsenic is best treated with reverse osmosis.  Lead removal will come via either high-grade carbon filters or reverse osmosis.

How Do I Fix The Problems?

A full plan of filtering, softening, preparing for drinking water, and monitoring is the way to go.

Whole House Water Filters

Clever design means whole house combo systems to meet your needs.

Best Water Softeners

Twin-tank design. No water softener model is more efficient or last longer.

Best Drinking System

Longest lasting, highest rated systems available.

Real-Time, WiFi-Driven Monitoring

A Water Doctors Exclusive.

Reverse osmosis systems rapidly growing in popularity.  If you care about the quality of your water, you’re probably going to buy one.

How will you know if it isn’t performing to spec?

That’s where WaterBot comes in.  Receive real-time alerts to your cell or iPad if anything goes wrong.

If you have a Kinetico system, you probably want a WaterBot.  If you have another system, you probably need a WaterBot.
