Lake in the Hills IL

The Lake in the Hills IL Water Treatment Department provides water to over 6,000 residents.

In 2011, additions to water treatment plants have increased Iron and Manganese removal to 1,000gpm (gallons per minute).

A few areas in town have softer water that has undergone specilized treatment.  Other parts of town have extremely hard water.

Water hardness aside, the entire community faces similar challenges with other water contaminants.

Lake in the Hills Water Hardness

Lake in the Hills water hardness ranges from 26-28gpg. The water is rated as extremely hard by the USGS, and is almost 6x harder than the national average. A professional-grade Water Softener will go a long way towards protecting your home’s plumbing and appliances from hard water damage.

Annual Water Quality Reports

Water quality can change from year-to-year. Our database of Annual Water Quality Reports will give you a better idea of “what’s in your water”:

2010 Lake in the Hills Annual Water Quality Report

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

Inorganic Contaminants

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

Contaminant Levels Found Health Limit Legal Limit Potential Effects
Arsenic 0.1 – 0.59 0ppb 10 Skin damage or problems with circulatory system, may have increased risk of cancer
Barium 0.97 – 1.3 2ppm 2 Increase in blood pressure
Hardness 26 – 28 NA gpg NA Increased energy consumption, damage to plumbing, appliances, fixtures, clothing
Iron 0.01 – 0.038 NA ppm 0.3 Increased energy consumption, damage to plumbing, appliances, fixtures, clothing
Manganese 1.1 – 8 50ppb 50 Black staining, decreased IQ in children
Nitrate 0.41 10ppm 10 Shortness of breath, “blue baby syndrome”
Selenium 1.2 50ppb 50 Hair or fingernail loss, numbness in fingers or toes, circulation problems
Sodium 23 – 140 NA ppm NA Hypertension

Organic Contaminants

Organics 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 preventative tool.

Contaminant Levels Found Health Limit Legal Limit Potential Effects
Dichloromethane 0.01 – 0.21 0ppb 5 Liver problems, increased risk of cancer
Vinyl Chloride 0.01 – 0.2 0ppb 2 Liver problems, increased risk of cancer

Disinfectants and Disinfection Byproducts

Disinfectants are added 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.

Contaminant Levels Found Health Limit Legal Limit Potential Effects
Chlorine 0.3 – 1.8 4.0ppm 4 Eye/nose irritation; stomach discomfort
Haloacetic Acids 2.3 – 56 0ppb 60 Increased risk of cancer
Total Trihalomethanes 19 – 29 0ppb 80 Liver, kidney or central nervous system problems; increased risk of cancer

Radionucliides

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 1.68 – 4.15 0pCi/L 15 Increased risk of cancer
Combined Radium 1.123 – 3.3 0pCi/L 5 Increased risk of cancer
