St Louis Park Water Softener and Drinking Water Guide

st louis park mn water hardness
The City of Saint Louis Park, MN provides drinking water to its residents from a groundwater source: 15 wells ranging from 286-1095 feet deep, that draw water from the Prairie Du Chien-Jordan, Mt. Simon, Jordan-St. Lawrence, and St. Peter aquifers.

The Utilities Division operates six water treatment plants and seven water storage facilities; and maintains more than 423 miles of water/sewer lines and 29 lift stations.

St Louis Park Water Discolored Water

You may notice occasional rusty, red discoloration in your water. This is from Iron that is naturally occurring in most well water sources in Minnesota.

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

  • St Louis Park Water Hardness

St Louis Park Water Softener Recommendations

The national average for water hardness is 5gpg (grains per gallon). St Louis Park water hardness is 18gpg, which is almost 4x 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.

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 1.05-2.4 0 10 Skin damage or problems w/ circulatory systems, increased risk of cancer
Barium 0.18-0.19 2 2 Increase in blood pressure
Fluoride 0.9-1.3 4 4 Bone disease;children may get mottled teeth
Nitrate 0.27-0.28 10 10 Blue-baby syndrome

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
Benzene .04-.33 0 5 Anemia, decrease in blood platelets, increased risk of cancer
cis-1,2-Dichloroethylene 0-16 70 70 Increased risk of cancer
Tetrachloroethylene 0.37-6.7 0 5 Liver problems; increased risk of cancer
trans-1,2-Dichloroethylene 0.15-1.1 100 100 Liver problems
Trichloroethylene 0.37-3.17 0 5 Liver problems; increased risk of cancer
Toluene 0.01-0.3 100 100 Nervous system, liver, or kidney problems
Vinyl Chloride 0-2.2 0 2 Increased risk of cancer

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 0.5-1.2 4 4 Eye/nose irritation; stomach discomfort
Chloroform 0.45-2.7 5.7 80 Nervous system depression, increase in kidney and liver tumors
Haloacetic Acids 1.1-4.7 0 80 Increased risk of cancer
Total Trihalomethanes 0.8-7.1 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 6% 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 8.4-42.8 0 15.4 Increased risk of cancer
Combined Radium 4.2-9.38 0 5 Increased risk of cancer
Radon 75-222 0 NA Increased risk of cancer
