Clean, reliable water is essential in a close-knit community like Emmaus. Dierolf Plumbing & Water Treatment has served the Lehigh Valley for 25+ years with Licensed Master Plumbers and Licensed Well Inspectors—and 1,000+ reviews from local homeowners. From a stroll at Shelter House to summer days at Emmaus Community Park & Pool and Friday lights at Emmaus High School, our work helps keep everyday life flowing.
The Borough’s water system draws primarily from local groundwater wells (2024 Consumer Confidence Report). Recent borough notices confirm PFOS/PFOA exceedances—for example, February 2025 results reported PFOS at 153 ppt and PFOA at 19 ppt (Public Notification, Feb 2025). Emmaus has secured PENNVEST funding to install granular activated carbon treatment for affected wells (PENNVEST award). The EPA has finalized national PFAS drinking water standards, with systems working toward compliance (EPA update).
As your water quality experts in Emmaus, we provide fast, proven solutions—certified filtration for PFAS, tailored reverse osmosis, softeners, neutralizers, UV, and professional plumbing—so your water is safe, great-tasting, and appliance-friendly.
Water Quality & Plumbing Services for Emmaus Homes
PFAS protection, now—not later. Borough testing and notices confirm PFOS/PFOA exceedances while long-term treatment is built (Feb 2025 Public Notice; 2024 CCR). Dierolf installs whole-home carbon and point-of-use reverse osmosis systems that target “forever chemicals” and other contaminants. For a deeper explainer, see our article Understanding the Impact of PFAS and Microplastics on Human Health, and our RO guidance How to Choose the Perfect Reverse Osmosis System. For federal standards and timelines, consult the EPA PFAS rule update.
Hard water & scale in Lehigh County. Groundwater in the region commonly trends hard, which shortens water-heater and appliance life and leaves spots and film. LCA’s hardness ranges explain why softening is a smart upgrade (LCA Water Hardness). We size and maintain efficient softeners; learn more in Salt-Based vs. Salt-Free Water Treatment and Is Your Water Softener Actually Working?.
Iron, sulfur (rotten-egg odor) & cloudy water. Local wells can have iron staining and hydrogen-sulfide odor. We install targeted media systems and ongoing service to restore clear, fresh water—see our Iron Filtration and Sulfur Filtration services.
Corrosion & low pH (blue-green stains). Acidic water can corrode pipes and fixtures over time. Our Neutralizers balance pH to protect plumbing and improve taste. When we tie treatment drains into your system, we follow best practices—see Why Air Gaps Matter.
Lead awareness & byproducts. The borough monitors lead/copper and disinfection byproducts such as HAA5 and TTHM (see the CCR). If your home is older or you’re replacing fixtures, we can test and install certified point-of-use filters. Start with professional water testing.
Community connections
We’re proud to serve neighbors across the Triangle—grab a sandwich at David’s Italian Market, meet friends at Café 23, or wind down at Yergey Brewing while our technicians handle your install.
Homeowner FAQs
Should I be concerned about PFAS in Emmaus? Borough notices report PFOS/PFOA above state MCLs, with GAC treatment funded and in progress (PENNVEST award; Feb 2025 notice). The EPA has set national MCLs and systems are working toward compliance (EPA update). For immediate peace of mind, we recommend certified carbon or RO at the tap or whole home.
How do I know if I need water testing in Emmaus? If you’ve noticed staining, scale, odors, or you own an older home, schedule professional water testing. We’ll sample for PFAS, lead, hardness, iron, sulfur, and more, then design a solution that fits your home and budget.
Does Dierolf handle both city and well water? Yes. We regularly serve borough customers and LCA’s Emmaus Consecutive Division (LCA Emmaus Division) and specialize in well inspection, pumps, pressure tanks, and treatment—plus full-service plumbing in Emmaus.
