Serving Lower Milford Township

Lower Milford Township occupies the southwestern corner of Lehigh County, bordering both Bucks and Montgomery Counties to the south and southwest. With ZIP codes 18036, 18041, 18049, and 18092 covering its gently rolling terrain of farms, woodlands, and historic villages, Lower Milford is one of the most rural communities in Lehigh County, and it intends to stay that way. The township holds the distinction of being home to the first Agriculturally Preserved Farm in Lehigh County, and as of 2025 there are 60 preserved farms totaling nearly 4,000 acres within its borders. Life here revolves around seasonal rhythms at places like Hausman Fruit Farm on Limeport Pike and the beloved Limeport Stadium, a historic baseball venue built in 1933 that still hosts games today. What most homeowners discover quickly is that life in Lower Milford Township also means relying almost entirely on a private well for water, and that makes knowing what is in that well critically important. Dierolf Plumbing and Water Treatment has been serving Lehigh County homeowners since 2009, always starting with a free professional water test before recommending any solution.

The vast majority of Lower Milford Township homes operate on private on-lot well and septic systems. Only the village of Limeport and a small number of homes in select developments are connected to public water through the Lehigh County Authority. For the hundreds of households on private wells scattered across the township’s preserved farmland and wooded hillsides, there is no regulated water testing, no annual Consumer Confidence Report, and no utility monitoring their water quality. That responsibility falls entirely on the homeowner. The Lehigh County Authority’s own hardness data for the Central Lehigh region, which draws from the same carbonate bedrock geology underlying Lower Milford Township, documents hardness in the range of 12 to 18 grains per gallon. Private wells in Lower Milford can test similarly high or higher, depending on the depth and location of the well. At that level, hard water causes real, measurable damage to water heaters, appliances, and plumbing. A properly sized water softener is the most effective long-term solution.

Lower Milford Township’s extensive agricultural land use creates specific risks for private well owners that go beyond hardness. With 60 preserved farms and active cropland covering a substantial portion of the township, nitrate contamination from fertilizer and manure runoff is a genuine and documented concern in rural Lehigh County groundwater. Pennsylvania DEP recommends annual nitrate testing for all private well owners, especially those near active farmland. Iron and manganese from the regional bedrock geology are also commonly found in Lower Milford wells, producing the orange or rust staining on fixtures and metallic taste in water that many residents accept as normal. Our iron filtration systems address this at the whole-house level, and reverse osmosis at the drinking water tap removes nitrates, iron, PFAS, and dissolved contaminants from the water your family drinks and cooks with.

Bacterial contamination is another priority for Lower Milford Township well owners. In an agricultural township where fields, pastures, and woodlands surround most properties, bacteria from surface runoff can enter wells, particularly after heavy rainfall or spring thaw. Older wells, shallow wells, and wells with deteriorating caps are most vulnerable. A UV disinfection system provides chemical-free whole-house bacterial protection. Our well systems services include pump and pressure tank maintenance as well as full water quality testing for bacteria, nitrates, hardness, iron, manganese, and pH. The Hosensack Creek, which runs through the township and has earned a Class A Wild Trout Stream designation, reflects the quality of Lower Milford’s natural environment. Keeping the private wells that feed hundreds of township homes to the same standard requires testing, attention, and the right treatment when it’s needed. Neighboring communities including Coopersburg, Upper Milford, and Upper Saucon share similar groundwater profiles, and our Lehigh County expertise translates directly to every Lower Milford home we serve.
