1. Chloroform – Potential effect: Cancer
2. Hexavalent Chromium – Potential effect: Cancer
3. Haloacetic acids (HAA5 and HAA9) – Potential effect: Cancer
4. Radium – Potential effect: Cancer
5. Total trihalomethanes – Potential effect: Cancer

These are five of the 25 contaminants analyzed by the Environmental Working Group (ewg.org).

13 of these contaminants are rated as exceeding EWG Health Guidelines.

Does Skokie have Lead contamination?

Yes, Skokie has lead in its water. The most recent Lead samples collected from 2015 through 2017 showed concentrations up to 5.2 parts per billion (ppb).

The legal limit for lead is 15 parts per billion. Being well-below this level is a good thing.

• Concentrations between 3.8 ppb and 15 ppb put a formula-fed baby at risk of elevated blood lead levels. Read more about the symptoms of Lead in water.

There is no safe level of lead for humans.

• The good news is that 99.99% of the lead can be removed.

What Can You Do?

Information about water quality in Skokie can be surprising.

But there are things you can do in your home to clean up your water.

To Remove Lead and Other Contaminants In Your Home:

There is one solution that beats Brita, PUR, and expensive whole house systems.

• It costs less per gallon.
• Needs fewer filter changes.
• And it doesn’t make your water taste weird.

• Use Berkey filters with activated carbon to filter out at least 90% of contaminants in your drinking water.
  • Berkey filters can also remove up to 99.99% of Lead in Skokie water.
    • They will remove Chloroform and Haloacetic acids as well.
  • Brita can filter 12 contaminants and Lead depending on the filter.
  • Note: We may receive a commission if you decide to purchase filters through links on this page.
• To filter out 23 of the 25 contaminants, consider a Reverse Osmosis water filtration system for your house.
  • These are more expensive than pitchers to purchase, but can be more effective.
  • They have the benefit of filtering out heavy hitters like:
    • 1,4-Dioxane – irritant of the eyes and respiratory tract. “Exposure may cause damage to the central nervous system, liver and kidneys.” (source)
    • Barium
    • Bromoform
    • Bromodichloromethane
    • Chloroform
    • Fluoride
    • Haloacetic acids – byproduct of chlorination*
    • Hexavalent chromium
    • Nitrate
    • Radium
    • Strontium
    • Total trihalomethanes – byproduct of chlorination*

*Chlorination is an effective method of disinfecting/treating drinking water. You can then use a water filter to reduce the effects of chlorination byproducts to get the safest, cleanest water possible.
