Here’s What You Need to Know About the Drinking Water in Naperville, IL
The Environmental Working Group (EWG) recently released an assessment that revealed Naperville, IL, has many contaminants in its drinking water. The known contaminants include:
The EPA also tests Naperville’s water regularly. However, they often do not set a legal limit for acceptable levels of contamination. So, instead, we suggest adhering to the limits set by the EWG. Their standards are more restrictive but result in cleaner and healthier water!
And if you do live in Naperville, there is a way to get cleaner and healthier water! Let’s see what contaminants are in the drinking water in Naperville, IL, and how Angel Water can help make it cleaner!
Chromium is an odorless and tasteless metallic element that can occur naturally in the environment. It can be found in things like rocks, plants and soil. However, industrial pollution also contributes to high levels of chromium in drinking water.
The two most common forms of chromium are trivalent chromium (chromium-3) and hexavalent chromium (chromium-6). The drinking water in Naperville, IL, tested positive for the later type.
Chromium-6 is a toxic form of the mineral. High enough levels of chromium-6 have been known to:
The EPA currently does not have a legal limit placed on how much chromium-6 can be in drinking water. The EWG, on the other hand, sets the maximum limit at 0.02 ppb (parts-per-billion) or less. Naperville’s water recently tested at 0.208 ppb, which is 10x above the EWG health guideline.
Total Trihalomethanes (TTHMs) form when chlorine and other disinfectants are used to treat drinking water. They are a group of four chemicals, also called disinfectant byproducts. These chemicals include:
Each of these chemicals can have harmful effects, including an increased risk of cancer and problems during pregnancy.
Currently, the EPA does not set a legal limit for the individual chemicals. Instead, it sets a limit for the total amount. That limit is 80 ppb. The EWG, on the other hand, sets a much lower limit of 0.15 ppb or less.
The most recent test results for the total trihalomethanes in Naperville showed that the level was at 34.6 ppb or 231x higher than the EWG health guideline.
Here are the test results for each of the individual chemicals:
Haloacetic acids also form when disinfectants such as chlorine are added to tap water. The phrase “haloacetic acids” refers to the group of five acids regulated by federal standards. They are:
Each of the acids listed increases the risk of cancer and are harmful during pregnancy. They are also genotoxic, which means they induce mutations and DNA damage when consumed in high enough levels.
Like the total trihalomethanes, the EPA tests these acids together and sets a standard limit of 60 ppb. The EWG, on the other hand, sets their health guideline at 0.1 ppb.
Naperville tested for all of the acids, combined, at 14.4 ppb, or 144x higher than the EWG health guideline.
Here are the levels of the individual acids that were tested in Naperville:
While the EPA regulates and tests public water systems, that information is not always complete. For example, certain contaminants and toxins are only tested every other year instead of annually. Or, as we saw with total trihalomethanes and haloacetic acids, they are tested at combined levels, rather than individually.
Testing water is a must for well-owners since the EPA does not regulate those systems. But even if you are on a public water system, having an outside resource test your water can be beneficial.
Not only will you learn which contaminants are in your water, but you can also track significant changes over time. This will help keep you informed so that you take steps to make your water cleaner and healthier!
