Delano Drinking Water Reports and Guide
The City of Delano, MN has four water wells that range in depth from 123 feet to 185 feet and pump water from the Quaternary Buried Artesian aquifer. In 2001, a 1.5 million gallon storage tank was added to support the City’s water network with 20 miles of pipe that range from 4″ in diameter to 16″.
In 2006, a new water treatment plant went into operation to remove iron and manganese which are the staining components of the water, not the hardness.

Delano Water Softener Recommendations
The national average for water hardness is 5gpg (grains per gallon). Delano water hardness is 26gpg, which is over 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.

Delano Water Reports
The City of Delano, MN 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.
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 | 1.12-7.59 | 0 | 10 | Skin damage or problems w/ circulatory systems, increased risk of cancer |
| Barium | 0.017 | 2 | 2 | Increase in blood pressure |
| Fluoride | 0.78-1.1 | 4 | 4 | Bone disease;children may get mottled teeth |
| Mercury | 0.13-0.16 | 2 | 2 | Kidney 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 | 0.1-2.2 | 4 | 4 | Eye/nose irritation; stomach discomfort |
| Chloroform | 2.55-6.6 | 5.7 | 80 | Nervous system depression, increase in kidney and liver tumors |
| Haloacetic Acids | 1.6-6.8 | 0 | 80 | Increased risk of cancer |
| Total Trihalomethanes | 0.1-9.7 | 0 | 60 | Increased risk of cancer |
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 | 2.1-12.2 | 0 | 15.4 | Increased risk of cancer |
| Combined Radium | 0.17 | 0 | 5 | Increased risk of cancer |
| Radon | 57-285 | 0 | NA | Increased risk of cancer |
