Serving Upper Saucon Township

Upper Saucon Township is one of the Lehigh Valley’s most sought-after communities, situated in the southeastern corner of Lehigh County about eight miles from Allentown and Bethlehem. Center Valley, Coopersburg, and the surrounding neighborhoods encompass ZIP codes 18036, 18015, 18034, and 18103, spanning rolling farmland, upscale residential developments, corporate campuses, and the 850-acre grounds of the world-renowned Saucon Valley Country Club. The township is home to DeSales University, Penn State Lehigh Valley, and the Promenade Shops at Saucon Valley, and it continues to attract families and professionals seeking top-rated schools and Lehigh Valley convenience. With that growth comes a pressing question that many homeowners only discover after moving in: what is in the water? Dierolf Plumbing and Water Treatment has been serving Lehigh County and the greater Lehigh Valley since 2009, and our first step is always a free professional water test before recommending any treatment.

Upper Saucon Township operates its own municipal water supply, sourcing treated surface water purchased from the City of Bethlehem and distributing it to approximately 7,300 customers across the township. The EWG Tap Water Database has identified 8 contaminants in the Upper Saucon Township Water Supply that exceed health guidelines, with total trihalomethanes (TTHMs) and haloacetic acids (HAA5) among the key disinfection byproducts of concern. These chemicals form when chlorine used for disinfection reacts with naturally occurring organic matter in surface water. While Upper Saucon’s water meets all federal legal standards, research links long-term exposure to disinfection byproducts with increased health risks. A reverse osmosis drinking water system installed at the kitchen tap is the most targeted and effective way to remove these byproducts, along with chlorine taste and odor, providing noticeably cleaner water for your family every day.

Hard water is another consistent reality for Upper Saucon Township homeowners. The Bethlehem water system, which sources from surface reservoirs in the Pocono region, delivers water that interacts with limestone bedrock formations throughout the Lehigh Valley, resulting in hardness levels commonly in the 7 to 10 GPG range. That is enough to cause real damage over time: scale accumulating inside water heaters and appliances, soap that lathers poorly, and the white residue on fixtures and glassware that no cleaning product can fully prevent. A professionally sized water softener is one of the most effective home investments a Center Valley or Upper Saucon homeowner can make, and our team can confirm your exact hardness level before sizing any system.

While the township’s water supply meets federal compliance standards, some Upper Saucon homeowners also benefit from additional peace of mind. The City of Bethlehem tested for all 29 PFAS compounds required under EPA’s UCMR5 program and reported non-detectable results for its 2025 Consumer Confidence Report, which is reassuring for municipal customers. However, properties in the more rural stretches of the township, near the Saucon Rail Trail or along Saucon Creek, that rely on private wells are not covered by municipal testing and should test independently for bacteria, nitrates, iron, and PFAS. Our well systems services cover comprehensive testing and any treatment needs. Neighboring communities in Lehigh and Northampton counties face similar water quality profiles, and our Lehigh Valley expertise means we understand the local conditions specific to Upper Saucon Township homes.
