Morrison's water system shows 8 contaminants above independent health guidelines, while remaining in compliance with federal standards. Legal limits and health guidelines are two different lines. Both are shown below, with sources, along with what a water filtration system in Morrison 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.
Long-term exposure risk: A radioactive metal. Long-term exposure raises bone cancer risk.
Radium is a naturally radioactive metal that leaches into deep wells from the bedrock, common in northern Illinois aquifers. Long-term exposure raises bone cancer risk, which is why it's federally limited to 5 picocuries per liter. Here's the good news: an ion-exchange water softener is an EPA-recognized treatment for it, the same equipment that fixes your hard water.
What treats it: Water softener (ion exchange), RO.
| Contaminant | Highest level tested | EWG health guideline | Times over | What treats it |
|---|---|---|---|---|
| Total trihalomethanes (TTHMs) | 11.9 ppb | 0.15 ppb | 79x | Catalytic carbon (+ RO backup) |
| Radium, combined (-226 & -228) | 3.04 pCi/L | 0.05 pCi/L | 61x | Water softener (ion exchange) or RO |
| Bromodichloromethane | 2.66 ppb | 0.06 ppb | 44x | Catalytic carbon (+ RO backup) |
| Haloacetic acids (HAA5) | 2.37 ppb | 0.1 ppb | 24x | Catalytic carbon (+ RO backup) |
| Chloroform | 8.79 ppb | 0.4 ppb | 22x | Catalytic carbon (+ RO backup) |
| Dichloroacetic acid | 1.50 ppb | 0.2 ppb | 7.5x | Catalytic carbon (+ RO backup) |
| Trichloroacetic acid | 0.497 ppb | 0.1 ppb | 5x | Catalytic carbon (+ RO backup) |
| Dibromochloromethane | 0.322 ppb | 0.1 ppb | 3.2x | 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 Morrison homes the baseline is a properly sized water softener, which also reduces the radium in this report through EPA-recognized ion exchange. 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 and reduces the radium in this report. The right first move for most Morrison homes.
Adds catalytic carbon: chlorine and the disinfection byproducts (up to 79x 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.
