ZeroTrace Water provides sales, professional installation, testing support and financing options. The regional research helps organize the questions that should be answered first.
Water Softener Systems
Reduce calcium and magnesium hardness that causes scale, soap inefficiency and appliance buildup.

Reverse Osmosis Systems
Use a point-of-use membrane system for drinking and cooking water after matching certified claims to the compounds of concern.

Start with the city, then confirm the address
The guides organize utilities, source-water profiles, PWSIDs, common ZIP research links and treatment questions. They do not replace the current bill or a property-specific test.

Ohio-specific evidence
Public systems, private wells and source-water risks are not interchangeable.
Ohio Drinking Water Watch identifies public systems by name, county, source type and PWSID. Ohio EPA also publishes PFAS sampling data and cyanotoxin monitoring information for participating treatment plants. Those records must be read by system, sample point, date and raw-versus-finished-water status.
- Lake Erie systems require source and cyanotoxin context
- Ohio River systems require correct utility and treatment-plant context
- Buried-valley aquifer systems require groundwater and wellfield context
- Private wells require property-specific laboratory testing
- Service lines and building plumbing can change tap-water conditions
Sales, installation and financing
Move from research to a workable home system
Equipment should fit the evidence, household flow, plumbing layout, maintenance plan and budget.
Review the source
Identify the provider, report, test result and the improvement the household wants.
Plan testing →Design the treatment train
Size each stage and verify model-specific reduction claims, flow and pressure.
Review installation →Review financing options
Ask about available programs. Approval, rates and terms depend on the third-party provider.

Clear limits make the information more useful.
The site does not claim that one utility result represents every household, that every address in a ZIP shares a provider, or that one treatment system solves every concern. Methodology and editorial-policy pages use an 18–24 month routine review window, with earlier corrections for material changes.
