McHenry IL

McHenry IL – the home of Garrelts Water Treatment!

During the first half of the 19th century, McHenry flourished as a resort area because of the Fox River, surrounding lakes and easy accessibility from Chicago.  Strong growth continued from farming and industries such as lumber, cigars, clay, food products and brewing that helped draw new residents to the area.

Today, the McHenry Water Division has developed 11 deep water wells to supply the city’s water needs.

The City of McHenry is partnering with the Illinois Environmental Protection Agency (IEPA) and the Illinois Department of Public Health to inform residents of the importance of having private wells tested. In recent years, volatile organic compounds (VOCs) have been found in groundwater in many areas of the state. Groundwater is the source of drinking water for private wells and the IEPA began a private well owner awareness campaign for education about the issue of VOCS in groundwater and well safety.

McHenry IL Water Hardness

McHenry water hardness is 23gpg, and is rated as extremely high by the USGS.

A reliable, professional-grade water softener like our E3 Water Softener is highly recommended.  A softener will protect your home’s plumbing, appliances, and water heater.

McHenry IL Water Quality Reports

The wells that supply McHenry with water can change from year-to-year. We have gathered the following reports to so you can see “what’s in your water”:

McHenry IL Targeted Well Water Contaminants

The contaminants in these reports have been listed by category below. All contaminants are within Legal Limits. Water contaminants that exceed the EPA’s Maximum Contaminant Level Goal (MCLG), aka Health Limit, have been highlighted below:

Inorganic Contaminants in McHenry Drinking Water

Inorganics include salts and metals like hard water and iron. Inorganic contaminants are mostly consumed through drinking water, and do not pass easily through skin. A Reverse Osmosis System is very effective at removing inorganic contaminants.

Contaminant Levels Found Health Limit Legal Limit Potential Effects
Antimony 0.36 – 2.5 6ppb 5.6 Increase in blood cholesterol, decrease in blood sugar
Arsenic 0.63 – 2.0 0ppb 10 Skin damage or problems with circulatory systems, and may have increased risk of getting cancer
Barium 0.07 – 0.13 2ppm 2 Increase in blood pressure
Hardness 23 NA gpg NA Increased energy consumption, damage to plumbing, appliances, fixtures, clothing
Iron .025 – 1.4 NA ppm 0.3 Increased energy consumption, damage to plumbing, appliances, fixtures, clothing
Manganese 4 – 131 50ppb 50 Black staining, decreased IQ in children
Nitrate 0.49 – 0.69 10ppm 10 Shortness of breath, “blue baby syndrome”
Selenium 0 – 1 50ppb 50 Hypertension

Organic Contaminants in McHenry IL Drinking Water

Organic contaminants can be natural, or manmade. Many organic chemicals easily pass through the skin, and make a Whole House Carbon Filter or a DMT Hybrid System a good tool to prevent exposure.

Contaminant Levels Found Health Limit Legal Limit Potential Effects
Di(2-ethylhexyl) Phthalate 0.2 – 1.19 0ppb 6 Endocrine disruptor, damage to liver and testes, reproductive effects, cancer

Disinfectants and Disinfection Byproducts in McHenry IL Drinking Water

Disinfectants are added by the city to kill bacteria. A new class of compounds are formed when disinfectants like chlorine react with other water contaminants. Many of these enter the body through inhalation, absorption through skin, and through drinking water. The DMT Hybrid System or a Whole House Carbon Filter would offer a good layer of protection for your home and family.

Contaminant Levels Found Health Limit Legal Limit Potential Effects
Chlorine 0.21 – 1.98 4.0ppm 4 Eye/nose irritation; stomach discomfort
Total Trihalomethanes 4.5 – 6.0 0ppb 80 Liver, kidney or central nervous system problems; increased risk of cancer

Radionucliides in McHenry IL Drinking Water

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

Contaminant Levels Found Health Limit Legal Limit Potential Effects
Alpha Emitters 0.313 – 0.99 0pCi/L 15 Increased risk of cancer
Combined Radium 1.09 – 1.3 0pCi/L 5 Increased risk of cancer

This information was compiled from City Water Quality Reports, the EPA, Illinois Department of Health, and the Environmental Working Group. Please contact us if any contaminants are missing, or levels that differ from those outlined on this page.
