Chaska Water Softener and Drinking Water Guide

City of Chaska MN water quality
The Chaska MN Water Treatment Facility treats up to 12.6 million gallons of water per day. Chaska has over 120 miles of water mains, 6 wells with depths ranging from 330-817 feet, and 4 water storage towers.

Well water naturally contains small levels of Iron and Manganese that can result in discolored water and result in staining as well as taste and odor complaints.

Occasionally low levels of 0-0.3ppm Iron will bleed through and cause discoloration.

Chaska Water Softener Recommendations

The national average for water hardness is 5gpg (grains per gallon). Chaska water hardness is 24-26gpg, which is 5-6x 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.

Chaska Water Reports

The City of Chaska 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
Arsenic 1.01-1.52 0 10 Skin damage or problems w/ circulatory systems, increased risk of cancer
Barium 0.017 2 2 Increase in blood pressure
Fluoride 1.1-1.6 4 4 Bone disease;children may get mottled teeth
Nitrate 0.2-7.4 10 10 Blue-baby syndrome

Organic Contaminants

Organic contaminants can come from either natural sources like algae, or man-made chemicals like Xylenes. 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
Xylenes 0.08 – 0.3 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 0.74 – 1.49 4 4 Eye/nose irritation; stomach discomfort
Chloroform 1.29 – 4.1 5.7 80 Nervous system depression, increase in kidney and liver tumors
Haloacetic Acids 3.1 – 5.1 0 80 Increased risk of cancer
Total Trihalomethanes 9.2 – 20.3 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 4.45 – 13.3 0 15.4 Increased risk of cancer
Combined Radium 1.2 – 3.8 0 5 Increased risk of cancer
Radon 264 0 NA Increased risk of cancer
