Minnetrista Water Softener and Drinking Water Guide

The City of Minnetrista provides drinking water to its residents from 5 water wells. These wells range from 253 to 787 feet deep, and draw water from the Franconia-Mt. Simon and Quaternary Buried Artesian aquifers.

The city also maintains over 28 miles of water mains to deliver water to homes and businesses.

Minnetrista Rust Stains

Ongoing problems with rusty water has been a growing problem in Minnetrista. It even made the news in the Star Tribune.

Rusty, red discoloration in your water comes from Iron and Manganese. Both metals are naturally occurring in well water sources like Minnetrista uses.

The Chlorine in city water oxidizes Iron. Oxidized iron CANNOT be removed by a Water Softener, and requires additional filtration.

  • National Hardness Average
  • Minnetrista Water Hardness

Minnetrista Water Softener Recommendations

The national average for water hardness is 5gpg (grains per gallon). Minnetrista water hardness is 24gpg, which is almost 5x harder than average.

A water softener will protect your water heater, plumbing, and appliances from hard water damage.  A high efficiency water softener will offer the same protection, but will use far less water and salt.

Minnetrista Water Reports

The City of Minnetrista 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
Arsenic 1.57-2.56 0 10 Skin damage or problems w/ circulatory systems, increased risk of cancer
Barium 0.27 2 2 Increase in blood pressure
Fluoride 0.88-2.3 4 4 Bone disease;children may get mottled teeth
Nitrate 0.13-0.16 10 10 Blue-baby syndrome

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 EffectsChlorine 0.762.3 4 4 Eye/nose irritation; stomach discomfortHaloacetic Acids 3.2 0 80 Increased risk of cancerTotal Trihalomethanes 0.8-5.3 0 60 Increased risk of cancer

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 4.1-18.0 0 15.4 Increased risk of cancer
Combined Radium 1.3-4.0 0 5 Increased risk of cancer
Radon 219-729 0 NA Increased risk of cancer
