Crystal Lake IL

The Water Division in Crystal Lake, IL provides over 4.9 million gallons of water each day.  In summer months, irrigation can increase demand to 10 million gallons per day!

Crystal Lake uses 11 wells to supply 5 different water treatment plants.  Once treated, tap water is stored in 8 storage tanks throughout the city.

Water must travel through over 175 miles of water main to reach the 39,000 residents in Crystal Lake.

Crystal Lake Water Hardness

Crystal Lake water hardness ranges from 21-24gpg.  The water is rated as extremely hard by the USGS, and is almost 5x harder than the national average.  A professional-grade Water Softener will go a long way towards protecting your home 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”:

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

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 0.55 0ppb 10 Skin damage or problems with circulatory system, may have increased risk of cancer
Barium 0.35 – 3.8 2ppm 2 Increase in blood pressure
Chromium 0 – 8.2 100ppb 100 Allergic dermatitis
Hardness 21 – 24 NA gpg NA Increased energy consumption, damage to plumbing, appliances, fixtures, clothing
Iron 0.08 – 0.12 NA ppm 0.3 Increased energy consumption, damage to plumbing, appliances, fixtures, clothing
Manganese 0 – 13 50ppb 50 Black staining, decreased IQ in children
Nitrate 0 – 0.16 10ppm 10 Shortness of breath, “blue baby syndrome”
Selenium 0 – 2.3 50ppb 50 Hair or fingernail loss, numbness in fingers or toes, circulation problems
Sodium 76 – 280 NA ppm NA Hypertension
Sulfate 0 – 63 NA ppm NA Catharsis, Dehydration from diarrhea

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
cis 1,2 – Dichloroethylene 0 – 6.43 70ppb 70 Increased risk of cancer
Di (2-ethylhexyl) Phthalate 0 0ppb 6 Endocrine disruptor, damage to liver and testes, reproductive effects, cancer
Dichloromethane 0 – 0.53 0ppb 5 Liver problems, increased risk of cancer
Methyl Tertiary Butyl Ether (MTBE) 0 – 0.89 NA ppb 9000 Increased risk of cancer, inhalation poses highest risk
Trichloroethylene 3.5 0ppb 5 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 0.616 – 2.1 4.0ppm 4 Eye/nose irritation; stomach discomfort
Haloacetic Acids 6.8 – 24.1 0ppb 60 Increased risk of cancer
Total Trihalomethanes 15.4 – 34.5 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 – 2.9 0pCi/L 15 Increased risk of cancer
Combined Radium 0.1 – 2.1 0pCi/L 5 Increased risk of cancer

Microbial Contaminants

Viruses and bacteria may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife.  Microbes are mainly consumed through drinking water.

Contaminant Levels Found Health Limit Legal Limit Potential Effects
Coliform Bacteria 5% 0% 0% Short term effects include diarrhea, cramps, nausea, and headaches

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.
