Is ELGIN tap water safe to drink?
ELGIN delivers tap water that earns a grade of D (55/100) from TapWaterSafety.org — a below-average rating, with multiple concerns including pfas contamination.
The utility serves 114,797 residents in ELGIN, drawing from surface water.
Public testing data identifies 16 contaminants in this water above EWG's health-based guidelines, including: Haloacetic acids (HAA9), Total trihalomethanes (TTHMs), Arsenic, Bromodichloromethane, Haloacetic acids (HAA5), Dibromochloromethane, Trichloroacetic acid, Dibromoacetic acid, Chloroform, Dichloroacetic acid, Chromium (hexavalent), Perfluorooctanoic acid (PFOA), Radium, combined (-226 and -228), Nitrate, Bromoform, Perfluorooctane sulfonate (PFOS). For most residents, a properly certified home filter at the kitchen tap is the most cost-effective way to reduce exposure to whatever's in your water. See our filter recommendations below, matched specifically to this utility's contaminant profile.
Quick actions for ELGIN residents
Top concerns in this water
Based on the most recent EPA and EWG data, these are the most significant water quality issues for ELGIN.
PFAS contamination
Severe concernPerfluorooctane sulfonate (PFOS), Perfluorooctanoic acid (PFOA) detected. PFAS are persistent chemicals linked to cancer and immune effects with no known safe exposure threshold.
Haloacetic acids (HAA9) significantly above health guideline
Moderate concernHaloacetic acids (HAA9) detected at 18.5 ppb, 309x above the EWG health guideline of 0.06 ppb.
Total trihalomethanes (TTHMs) significantly above health guideline
Moderate concernTotal trihalomethanes (TTHMs) detected at 37.6 ppb, 251x above the EWG health guideline of 0.15 ppb.
Arsenic significantly above health guideline
Moderate concernArsenic detected at 0.906 ppb, 226x above the EWG health guideline of 0.004 ppb.

Recommended water filters for ELGIN
Filters matched to the specific contaminants in this water supply.
Reverse Osmosis or NSF P473 certified carbon
$80-$750Activated carbon and RO are the only technologies proven to remove PFAS at certified levels.
Carbon block (NSF/ANSI 42 + 53)
$40-$750Activated carbon is highly effective for disinfection byproducts like TTHM and HAA5.
Reverse Osmosis
$249-$750Arsenic is most effectively removed by reverse osmosis. Some specialized adsorptive filters also work.
