Eden Prairie Water Reports and Guides

The City of Eden Prairie draws water from the Jordan and Prairie Du Chien-Jordan aquifers through 15 wells that range from 379-418 feet deep.

Once treated, the city delivers water through over 265 miles of water mains.

  • Soft Water
  • Eden Prairie Water Hardness

Eden Prairie Water Softener Recommendations

Eden Prairie water hardness is rated as “moderately hard” by the USGS.  The untreated well water is almost as hard as the infamous Frederick Miller Spring in Eden Prairie.  But the city uses a chemical treatment process that alters the pH in order to decrease the water hardness from 18 grains down to around 5-6 grains. A professional-grade Water Softener can reduce the hardness even more for added protection.

Eden Prairie Water Reports

The City of Eden Prairie does regular water testing and publishes the results in Annual Drinking Water Reports. These reports explain which water contaminants, and what levels have been found.

s

The EPA has two standards for drinking water contaminants:

MCL: Maximum Contaminant Level
The legal limit for a certain contaminant

MCLG: Maximum Contaminant Level GOAL
The level with ZERO HEALTH RISKS, aka the “Health Limit”

All water contaminants meet the EPA’s “Legal Limit”. Contaminants that exceed the EPA’s Health Limit have been highlighted below.

Inorganic Contaminants

Inorganic contaminants include natural and manmade salts and metals. You are mostly exposed to inorganics through drinking water, most do not easily pass through skin. Carbon Filters (refrigerator and faucet filters) have almost ZERO impact on these contaminants. Reverse Osmosis very effective at removing inorganic contaminants.

Contaminant Amount Found Health Limit Legal Limit Potential Effects
Barium 0.03-1.03 2 2 Increase in blood pressure
Fluoride 0.83-1.2 4 4 Bone disease;children may get mottled teeth

Organic Contaminants

Organic contaminants can come from either natural sources like algae, or man-made chemicals. You can be exposed through drinking water, absorption through skin (bathing), and inhalation. This makes a Hybrid Filter System, or Whole House Carbon Filter a good preventative tool.

Contaminant Amount Found Health Limit Legal Limit Potential Effects
cis-1,2-Dichloroethylene 0.22-0.4 70 70 Increased risk of cancer
Xylenes 0.0002 1.8 100 Nervous system damage

Disinfectants and Disinfection Byproducts

Disinfectants are added to kill bacteria. Disinfectants like Chlorine react with other chemicals and create “Disinfection Byproducts. These chemicals enter the body through inhalation, absorption through skin, and drinking water. A Whole House Carbon Filter is a good preventative tool in addition to a Drinking Water System for these compounds.

Contaminant Amount Found Health Limit Legal Limit Potential Effects
Chlorine 0.8-1.3 4 4 Eye/nose irritation; stomach discomfort
Haloacetic Acids 4.3-11.1 0 80 Increased risk of cancer
Total Trihalomethanes 27-32 0 60 Increased risk of cancer

Microbial Contaminants

Microbes like bacteria and virus come from a variety of sources. These include water main breaks, leaky septic systems, livestock, and wildlife. Microbial contaminants are mainly consumed through drinking water. Carbon Filters and Water Softeners do not offer any protection against microbes, but UV Treatment is very effective.

Contaminant Amount Found Health Limit Legal Limit Potential Effects
Total Coliform Bacteria 1-5% 0 5 Not a health threat itself; it is used to indicate whether other potentially harmful bacteria may be present
*Upon re-testing, 0% Coliform Bacteria was detected.

Radionuclide Contaminants

Radionuclides in water may occur naturally, or come from oil and gas production or mining activities. These can be inhaled, or consumed through drinking water.

Contaminant Amount Found Health Limit Legal Limit Potential Effects
Alpha Emitter 1 0 15.4 Increased risk of cancer
Radon 85 0 NA Increased risk of cancer
