Shakopee Water Hardness & Drinking Water Quality

Shakopee City Water Background

The City of Shakopee MN draws water from 18 wells with depths ranging from 218-800 feet. 14 of these wells tap the Jordan Aquifer, while others draw from the Mt. Simon and Franconia/Ironton-Galesville Aquifers.

The City of Shakopee frequently tests for Nitrates due to the high average level. Nitrate levels may rise quickly for short periods of time because of rainfall or agricultural activity. Nitrate in drinking water at levels above 10 ppm is a health risk for infants of less than six months of age. If you are caring for an infant, you should ask advice from your health care provider.

Shakopee Water Hardness

Shakopee water hardness ranges from 24-26gpg.  This is rated “extremely hard” by the USGS (hard water info).  A High Efficiency Water Softener or Saltless Softener can provide protection against hard water damage.

Shakopee Water Quality Reports

The City of Shakopee 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:

2009 Shakopee Water Report
2007 Shakopee Water Report
2005 Shakopee Water Report

The EPA has established two standards for additional contaminants in tap water:

MCL: Maximum Contaminant Level – The maximum allowable level of a certain contaminant, aka the “Legal Limit”
MCLG: Maximum Contaminant Level GOAL – The level where studies have found ZERO HEALTH RISKS, aka the “Health Limit”


All water contaminants meet the EPA’s “Legal Limit”. Certain water contaminants exceed the EPA’s Health Limit and have been highlighted:

Inorganic Contaminants

Inorganic contaminants include salts and metals like Hard Water and Copper. Inorganics are mostly consumed through drinking water, and most do not easily pass through skin. Carbon Filters (refrigerator and faucet filters) have virtually ZERO impact on these contaminants. Reverse Osmosis and the LINX Evolution are very effective at removing inorganic contaminants.

Contaminant Levels Found Health Limit Legal Limit Potential Effects
Arsenic 1.38 0 10ppb Skin damage or problems w/ circulatory systems, increased risk of cancer
Barium .24 – .41 2 2ppm Increase in blood pressure
Fluoride 1.1 – 1.3 4 4ppm Bone disease (pain and tenderness of the bones); children may get mottled teeth
Hard Water 24 – 26gpg NA NA Damage to plumbing, appliances, glassware
Nitrate 7.0 – 9.8ppm 10 10ppm Infants below the age of six months who drink water containing nitrate in excess of the MCL could become seriously ill and, if untreated, may die. Symptoms include shortness of breath and blue-baby syndrome.
Sodium 5.9 – 39ppm NA NA Hypertension
Sulfates 18 – 57.3ppm NA NA Catharsis, Dehydration from diarrhoea

Organic Contaminants

Organic Contaminants can be from natural sources like algae, or man-made like Ethylbenzene. Many organic chemicals easily pass through the skin, and make a Pureoflow, DMT Hybrid System, or Whole House Carbon Filter a good preventative tool.

Contaminant Levels Found Health Limit Legal Limit Potential Effects
Di(2-ethylhexyl) phthalate 0.16 – 0.58 0 6ppb Reproductive difficulties; liver problems; increased risk of cancer

Disinfectants and Disinfection Byproducts

Disinfectants are added to control bacteria. When disinfectants like Chlorine react with other water contaminants, a new class of compounds are formed called “Disinfection Byproducts. Many of these chemicals can enter the body through inhalation, absorption through skin, and through drinking water. A Whole House Carbon Filter is a good preventative tool in addition to a Drinking Water System for these compounds.

Contaminant Levels Found Health Limit Legal Limit Potential Effects
Bromodichloromethane 1.09 – 4.8 0 80ppb Increased risk of cancer, damage to liver, kidneys, and nervous system
Chlorine 0.7 – 2.12 4 4ppm Eye/nose irritation; stomach discomfort
Dichloroacetic Acid 0.22 – 2.0 0 60ppb Irritant and corrosive to the eyes, skin and respiratory tract
Haloacetic Acids 0.7 – 4.0 0 60ppb Increased risk of cancer
Trihalomethanes 3.8 – 14.2 NA 80ppb Liver, kidney or central nervous system problems; increased risk of cancer

Microbial Contaminants

Bacteria, Virus, and Cysts come from a variety of sources including water main breaks, sewage treatment plants, septic systems, agricultural livestock operations, and wildlife. Microbes are mainly consumed through drinking water. Carbon Filters and Water Softeners do not offer any protection against microbes, but UV Treatment and Ultrafiltration are very effective.

Contaminant Levels Found Health Limit Legal Limit Potential Effects
Total Coliform Bacteria* 1% 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.

Radionuclides

Radionuclides may occur naturally, or be the result of oil and gas production or mining activities. These can be inhaled, or consumed through drinking water.

Contaminant Levels Found Health Limit Legal Limit Potential Effects
Alpha Emitters 3.4 – 6.7 0 15.4pCi/L Increased risk of cancer
Combined Radium 1.4 – 3.8 0 5pCi/L Increased risk of cancer
Radon 68 – 231 0 NA Increased risk of cancer
