Maple Grove Water Softener and Drinking Water Guide

maple grove mn drinking water
The City of Maple Grove MN draws water from 12 wells ranging from 157-715 feet deep, which get water from the Franconia-Mt. Simon aquifer, the Quaternary Water Table aquifer, and the Mt. Simon aquifer.

Iron and Manganese in Maple Grove Water

Maple Grove’s raw well water source contains excessive amounts of Iron and Manganese. These minerals require Filtration or they will cause rusty, brownish-red water, spotting of clothes, staining of sinks, tubs and toilets, and foul taste and odor.

In 1987 Maple Grove installed a water treatment plant that injects Chlorine and Potassium Permanganate into the water to oxidize these minerals, and then remove them with filter beds of specially coated silica sand. Chlorine and fluoride are added last to two storage tanks that hold 3.5 million gallons of water.

Maple Grove Water Softener Recommendations

The national average for water hardness is 5gpg (grains per gallon). Maple Grove water hardness ranges from 22-25gpg, which is 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.

Maple Grove Water Reports

The City of Maple Grove 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.

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 0.011-0.12 2 2 Increase in blood pressure
Fluoride 0.79-1.6 4 4 Bone disease;children may get mottled teeth
Manganese 0.03 0.05 0.05 Lowered IQ in children, black stains, damage to plumbing and appliances
Nitrate 0.06-0.1 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
Ethylbenzene 0.35-0.70 700 700 Liver or kidney problems
Tetrachloroethylene 0.4-0.5 0 5 Liver problems, increased risk of cancer
Toluene 0.9-1.8 100 100 Nervous system, liver, or kidney problems
Xylenes (total) 0.4-0.8 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 0.47-1.3 4 4 Eye/nose irritation; stomach discomfort
Chloroform 2.01-3.7 5.7 80 Nervous system depression, increase in kidney and liver tumors
Haloacetic Acids 1.4-5.1 0 80 Increased risk of cancer
Total Trihalomethanes 12.7-28.0 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% 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 15 0 15.4 Increased risk of cancer
Combined Radium 10.4 0 5 Increased risk of cancer
Radon 43-408 0 NA Increased risk of cancer
