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:
2012 Shakopee Water Report
2010 Shakopee Water Report
2009 Shakopee Water Report
2007 Shakopee Water Report
2005 Shakopee Water Report
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 | 0 | 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 |
