Nestled in the scenic rolling hills of Upper Milford Township in Lehigh County, Zionsville, PA 18092 represents the best of rural Pennsylvania living. With approximately 3,300 residents, this affluent community boasts a median household income exceeding $110,000 and strong family values. But beneath the picturesque farms and historic barns, many homeowners face hidden water quality challenges that affect daily comfort, appliance longevity, and family health.
Whether drawing water from private wells or connected to municipal supplies through Lehigh County Authority, Zionsville families encounter unique groundwater issues—from excessive hardness to emerging PFAS contamination. That’s where Dierolf Plumbing & Water Treatment comes in. With over 25 years of experience, more than 1,000 five-star reviews, and Licensed Master Plumbers and Licensed Well Inspectors on staff, we deliver customized, science-backed water treatment solutions designed specifically for Lehigh Valley’s challenges.
Hard Water: Lehigh Valley’s Most Prevalent Challenge
White, chalky buildup on fixtures, reduced water pressure, and struggling appliances signal hard water—Zionsville’s most common issue. Lehigh Valley groundwater typically measures 10+ grains per gallon, well into the “very hard” category. This excessive mineral content causes scale formation, reduces appliance efficiency by years, and creates difficulties with soap and cleaning. Hard water isn’t just inconvenient—it’s expensive, driving up energy bills and shortening water heater lifespan.
Dierolf’s whole-house water softening systems eliminate calcium and magnesium through ion-exchange, delivering softer skin, shinier hair, spotless dishes, and significant savings on energy and maintenance. Our systems are custom-sized for your home’s specific hardness levels and usage patterns.
PFAS, Iron, and Well Water Contamination
PFAS “forever chemicals” have been detected in 47 Pennsylvania counties, with the nearby Borough of Emmaus actively addressing remediation efforts. Pennsylvania established strict limits of 14 parts per trillion for PFOA and 18 ppt for PFOS, though federal EPA standards are even lower. For Zionsville well owners—especially near potential contamination sources—advanced reverse osmosis and activated carbon filtration provide proven PFAS removal.
Many well owners also discover reddish-brown stains indicating iron and manganese contamination. Iron levels above 0.3 ppm cause discoloration, metallic taste, and orange-tinted laundry, while manganese creates blackish stains. Our iron filtration systems capture both dissolved and oxidized metals before they reach your taps. Learn more in our article on addressing PFAS and water quality concerns.
Low pH, Corrosion, and Bacteria Protection
Acidic water with pH below 7.0 silently destroys copper pipes and can leach lead into drinking water, creating serious health risks for children. Blue-green stains and pinhole leaks indicate corrosive water requiring immediate acid neutralization. Dierolf’s systems raise pH levels safely, protecting plumbing infrastructure and preventing metal leaching. Our Water Science 101 guide explains pH balance in everyday terms.
Private well owners must also safeguard against bacterial contamination from surface water, septic systems, or agricultural runoff. UV disinfection systems destroy E. coli, coliform bacteria, and other pathogens without chemicals—providing a final barrier of protection for every drop. Combined with proper filtration, UV systems ensure microbiologically safe water for your family.

Frequently Asked Questions About Water Treatment in Zionsville
How do I know if I need water treatment in Zionsville? Comprehensive laboratory testing is essential, as many contaminants are invisible. Signs include fixture staining, scale buildup, dry skin after showering, metallic tastes, or if you haven’t tested well water annually. Dierolf offers complimentary testing and detailed result explanations with customized treatment recommendations.
What’s the difference between softeners and filtration systems? Water softeners address hardness minerals causing scale and appliance damage through ion-exchange. Filtration systems remove specific contaminants like iron, bacteria, PFAS, or sediment through specialized media. Many Zionsville homes benefit from both—softeners for regional hard water plus targeted filtration for well-specific issues identified through testing.
How often does maintenance cost? Water softeners need salt replenishment and annual service ($100-300/year). Iron filters require periodic media replacement ($150-400/year). Reverse osmosis systems need filter changes and membrane replacement ($150-250/year). UV systems require annual bulb replacement ($100-200/year). Dierolf offers comprehensive service plans including all maintenance, priority emergency service, and repair discounts.
