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) 246-2868.
Long-term exposure risk: Long-term elevated exposure is associated with increased bladder cancer risk in the research behind EPA's own limits.
DBPs, disinfection byproducts, mostly trihalomethanes or THMs, form when the chlorine the city uses to disinfect reacts with natural organic matter in the source water. The disinfection itself is necessary; the byproducts are the problem, long-term elevated exposure is associated with increased bladder cancer risk in the research EPA cites, which is why they're federally capped at 80 parts per billion. Catalytic carbon strips them out at your house.
What treats it: Catalytic carbon system.
| Contaminant | Highest level tested | EWG health guideline | Times over | What treats it |
|---|---|---|---|---|
| Total trihalomethanes (TTHMs) | 7.31 ppb | 0.15 ppb | 49x | Catalytic carbon (+ RO backup) |
| Bromodichloromethane | 2.26 ppb | 0.06 ppb | 38x | Catalytic carbon (+ RO backup) |
| Dibromochloromethane | 1.74 ppb | 0.1 ppb | 17x | Catalytic carbon (+ RO backup) |
| Chloroform | 3.31 ppb | 0.4 ppb | 8.3x | Catalytic carbon (+ RO backup) |
| Haloacetic acids (HAA5) | 0.383 ppb | 0.1 ppb | 3.8x | Catalytic carbon (+ RO backup) |
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.
For most Davis Junction homes the baseline is a properly sized water softener. From there, the report tells us what else matters: carbon for the disinfection byproducts, a drinking-water system for the serious lines, and up the ladder from there. See the systems, or start with the free personal report.
Start where your budget is. Every tier is installed by a licensed plumber, tested at handoff, and includes the first year of care.
Properly sized water softener with full install hardware. Ends the hard water. The right first move for most Davis Junction homes.
Adds catalytic carbon: chlorine and the disinfection byproducts (up to 49x the guideline here) gone at the wall.
Adds the drinking-water RO tap and UV protection. The serious lines, handled.
Every tap purified: whole-home RO, remineralized to pH 7.0 to 8.5, sealed storage that never sits still (24/7 UV recirculation), twin softening, leak protection, and our signature copper vortex stage.
Multiple buildings, outbuildings and barns, high-flow engineering, bespoke copper work. Designed one-on-one with the owner.
