What Middletown's Water Means for Your Home
Hardness: 30 PPM - Low Concern
Middletown's water is slightly hard at 30 PPM. Most households won't notice any issues at this level. Scale buildup is minimal, and a water softener would be overkill. Middletown is softer than 82% of US cities. If you're thinking about water treatment, contaminant filtration is where to focus your money, not softening.
Contaminants & Safety
Disinfection byproducts are the notable finding here. Middletown's water has TTHMs at 5.98 ppb and HAA5 at 1.46 ppb — both within legal limits, but the EWG health guidelines are far stricter. These byproducts form when chlorine reacts with organic matter during treatment. A whole-house activated carbon filter reduces both chlorine and its byproducts. Want the full picture? Request your utility's annual Consumer Confidence Report.
What's in the Treatment Process
Chromium-6 was detected at 0.158 ppb, which is 7.9x the EWG health guideline. There's no separate federal limit for chromium-6, only total chromium. A reverse osmosis system is the most effective removal method. All measurements are within federal legal limits. The EWG guidelines represent a more conservative, health-based standard.

Good news for Middletown residents. Your water quality is generally good. Most homes in this area do not need a water softener. If you have concerns about lead (especially in buildings constructed before 1986) or chlorine taste, a point-of-use filter is the most practical and cost-effective solution.
Quick Fix for Chlorine: Shower Filter
At 1.1 mg/L chlorine, many Middletown residents notice dry skin, brittle hair, and that "pool smell" in the shower. A shower filter installs in 5 minutes, no tools needed.

About Middletown's Water Supply
Water Utility: Artesian Water Company
Water Source: Artesian Water wells (Surface Water)
Population Served: 17,700
Hardness: 30 PPM (1.8 grains per gallon)
Middletown's drinking water comes from surface sources — Artesian Water wells. Surface water requires more extensive treatment than groundwater, including coagulation, filtration, and disinfection. This heavier chlorination is why disinfection byproducts tend to be higher in surface-supplied systems. On the upside, surface sources often deliver softer water than deep aquifers. The system serves 18,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request Artesian Water Company's Consumer Confidence Report (CCR) or test your own tap.
