Union Water Quality Report

  • Water Hardness: 18.6 GPG (318.1 ppm)
  • Classification: Very Hard
  • Water Source: County Municipal Groundwater Systems

To put this in perspective, the U.S. average water hardness is around 5 GPG. Union's water is more than three times harder than the national average. A rating of 18.6 GPG means that for every gallon of water that cycles through your home, it carries the mineral equivalent of 18.6 grains of dissolved rock.

The hidden cost of Union's 18.6 GPG water is significant. Each year, your plumbing system accumulates approximately 4.4 pounds of calcium carbonate scale. This rock-like deposit forms inside your water heater, dishwasher, and washing machine.

  • Gas & Electric Water Heaters: Scale acts as insulation between the heating element or burner and the water. At this hardness level, your heater works up to 25% harder to produce hot water, increasing your energy bills from Dayton Power & Light Co.
  • Appliance Lifespan: A standard water heater should last 12-15 years. With Union's water, that lifespan is slashed to just 6 years.
  • Daily Costs: You'll use 30-50% more detergent, soap, and shampoo just to get an effective lather, adding a consistent extra cost to your household budget.

While legally safe to drink, very hard water has a noticeable impact on skin and hair. The high mineral content reacts with soaps to form a scummy residue that doesn't rinse away cleanly. This can lead to:

  • Dry, itchy skin and aggravated conditions like eczema.
  • Dull, brittle hair that is difficult to manage.
  • A persistent feeling of residue on your skin after showering.

This is particularly noticeable for families, where sensitive skin can be irritated and preparing baby formula with heavily mineralized water is a concern.

For water hardness above 15 GPG, proactive treatment is a financial necessity, not a luxury. The best solution for Union homes is a whole-house water softener paired with an under-sink reverse osmosis (RO) system for drinking water.

A professionally installed softener (averaging $1,500) will pay for itself in approximately 7.6 years. This calculation is based on your estimated annual savings of $198 from reduced energy consumption, lower detergent costs, and avoiding the premature replacement of expensive appliances. The RO system eliminates the need for bottled water, saving an average family an additional $600-$900 per year.

Frequently Asked Questions

Is 18.6 GPG really that bad for my Union home?

Yes, 18.6 GPG is categorized as 'very hard' and is high enough to cause significant, costly damage over time. It will shorten the life of a water heater to just 6 years, leave stubborn spots on glassware, and require you to use much more soap to get things clean.

What is the best water filter for very hard water like in Montgomery County?

Given the severity of the hardness, a salt-based, ion-exchange water softener is the only truly effective solution for protecting your entire home. For purified drinking water, we recommend pairing it with an under-sink reverse osmosis (RO) filter.

How quickly does a water softener pay for itself in Union, Ohio?

With potential annual savings of $198 on energy, detergents, and extending appliance life, a typical water softener system will pay for itself in about 7.6 years. After that, the savings directly benefit your household budget.

Data Transparency & Methodology

Water and savings figures for Union, Ohio are generated by our plumbing analytics engine (v1.1). Methodology highlights:

Water hardness (PPM / GPG)

Sourced or inferred from municipal water-quality reporting (including Consumer Confidence Report–style hardness / mineral data where published). Values represent typical service-area water for modeling scale risk—not a lab test for your specific tap.

epa.gov

Economics (scale, appliances, payback)

Engineered estimates — scale buildup potential, water-heater wear, and water-softener payback use industry-typical curves (grain capacity, regeneration salt use, and heater efficiency assumptions) applied to your local hardness and usage profile. Figures are illustrative; a licensed plumber should validate sizing.

Electricity rates (optional cost context)

Where water-heating or pump energy cost appears, EIA state average retail electricity prices ($/kWh) may be used as a benchmark—not your exact utility time-of-use bill.
