Iowa DNR Test Reveals High Concentration Of ‘Forever Chemicals’ In Central City Drinking Water | News


CENTRAL CITY, Iowa (KWWL) – A recent test conducted by the Iowa Department of Natural Resources on one of two public wells in Central City found levels near safe limits set by the EPA.

In one PFAS Information Report posted on the Central City website, the city said the Iowa DNR tested the well on Feb. 7 for per- and polyfluoroalkyl substances, commonly known as PFAS. According to the Iowa DNR, the chemicals are often used in carpets, clothing, upholstery, paper food wrappers, chrome plating and some fire-fighting foams.

According to a dashboard of PFAS survey results on the Iowa Department of Natural Resources website, the sample found a combined concentration of 61 parts per trillion, according to the Iowa Department of Natural Resources.

The current EPA Lifetime Health Advisory safety limit is 70 parts per trillion or 0.00007 parts per million.

On its website, the Iowa DNR said research suggests exposure to the compounds could lead to health problems such as developmental defects in babies and certain types of cancer.

The Iowa DNR recently developed an action plan to develop a comprehensive response to PFAS in Iowa.

In the PFAS information report posted on the Central City website, the city said the Iowa DNR dictated how the city would respond.

The city said it should begin monitoring PFAS levels with testing beginning in the second quarter of 2022, between April 1 and June 30, 2022.

According to the city, two types of home filters have been shown to be effective in removing PFAS.

Granular activated carbon filters can be effective if customers regularly replace the carbon filters at the intervals recommended by the filter manufacturer.

Reverse osmosis systems can also be very efficient, but waste two to four gallons for every gallon treated. The city said they should be “limited to points where water is used for drinking.”

The National Sanitation Foundation has a list of products that claim to eliminate PFAS on their website.
