Davis Junction's water system shows 5 contaminants above independent health guidelines. Legal limits and health guidelines are two different lines. Both are shown below, with sources, along with what a water filtration system in Davis Junction should actually address. Call (815) 420-4731.
All 5 of them, worst first, from Davis Junction's own published tests. Tap any contaminant to see what it is, how it gets into the water, and what long-term exposure is linked to.
Long-term exposure: The research behind EPA's own limit associates long-term elevated exposure with increased bladder cancer risk. Several studies also flag effects during pregnancy.
Nobody added this. TTHMs are the sum of four byproducts that form when the chlorine used to disinfect your water meets leaves, algae and other organic matter in the source. The disinfection is necessary. The byproducts are what it costs you.
Handled by: Carbon filter at the main line
Long-term exposure: EPA classifies it as a probable human carcinogen. Long-term exposure is associated with liver, kidney and intestinal effects.
Forms when chlorine meets naturally occurring bromide in the source water. Of the four trihalomethanes, this is one of the two the research treats most seriously.
Handled by: Carbon filter at the main line
Long-term exposure: EPA classifies it as a possible human carcinogen; animal studies show liver damage at sustained exposure.
Another chlorine-plus-bromide byproduct. It travels with the other three, so where you find one you almost always find all four.
Handled by: Carbon filter at the main line
Long-term exposure: Classified by the international cancer agency as possibly carcinogenic to humans, with liver and kidney effects at sustained high exposure.
The most common of the four trihalomethanes, and usually the largest single share of the total. It forms in the pipes on the way to your house, which is why the level at your tap can be higher than the level leaving the plant.
Handled by: Carbon filter at the main line
Long-term exposure: The second major byproduct family. Long-term exposure is associated with increased cancer risk, and some studies flag developmental effects.
HAA5 is the sum of five haloacetic acids, formed the same way the trihalomethanes are. Federally capped at 60 parts per billion. The independent health guideline is 0.1.

Levels are the utility's own most recent published test results as compiled by the EWG Tap Water Database. "Times over" compares against EWG's independent health guideline, not the federal legal limit; this system meets federal limits.
