When your tap water leaves behind stubborn orange stains or your morning coffee tastes metallic, you’re experiencing the water quality challenges many Macungie homeowners face. This historic Lehigh County borough of 3,200 residents—known for the beloved Das Awkscht Fescht and charming Victorian architecture—sits atop geological formations that create distinct water chemistry concerns affecting plumbing longevity and family comfort.
For over 25 years, Dierolf Plumbing & Water Treatment has served as southeastern Pennsylvania’s trusted water quality partner, earning more than 1,000 five-star reviews. Our Licensed Master Plumbers and Licensed Well Inspectors bring deep local knowledge to every service call, understanding the specific challenges that Macungie’s water presents—whether your home draws from Lehigh County Authority’s municipal system or relies on a private well.
Hard Water and Mineral Buildup
Macungie residents face water hardness ranging from 12 to 18 grains per gallon through the Lehigh County Authority’s Central System—firmly in the “hard” to “very hard” category. This mineral content creates spotty glassware, white deposits on fixtures, and accelerated appliance wear. Water heaters working with hard water experience up to 30% decreased efficiency from scale buildup, while washing machines and dishwashers suffer shortened lifespans.
Modern water softening systems use ion exchange technology to remove hardness minerals before they enter your plumbing. Our clients consistently report softer laundry, spot-free dishes, improved soap lathering, and extended appliance life. Learn more about the chemistry affecting your water.
Iron, Manganese, and pH Problems
Iron and manganese infiltrate Pennsylvania water systems—especially deeper wells—causing orange or black staining and metallic taste. These minerals exceed safe aesthetic levels (0.3 ppm for iron, 0.5 ppm for manganese) in many local wells, creating unsightly stains on fixtures and laundry while harboring bacteria that produce slimy biofilms in pipes.
Acidic water with pH below 7.0 represents an even more serious threat, slowly dissolving copper pipes and brass fixtures. This creates blue-green stains, pinhole leaks, and potentially dangerous metal leaching—particularly concerning in homes built before 1986. Our acid neutralizing systems raise pH to protective levels while iron filtration removes staining minerals. Explore why pH balance matters for your plumbing.
PFAS and Bacterial Concerns
The Lehigh County Authority has detected low levels of PFAS “forever chemicals” in some water sources and approved funding in 2023 to study treatment options for its Allentown Division sources. The EPA finalized new PFAS regulations in April 2024 establishing maximum contaminant levels. Homeowners concerned about these emerging contaminants can install reverse osmosis systems for immediate protection at drinking water taps.
For private well owners, bacterial contamination poses serious risks. Approximately half of tested Pennsylvania wells show at least one water quality problem, with coliform bacteria occurring in about half of wells. Annual testing for bacteria and nitrate is essential, along with periodic checks for pH, hardness, iron, and manganese. UV filtration systems provide continuous disinfection without chemicals. Our guide on well water and local geology explains testing protocols.

Frequently Asked Questions
How often should Macungie well owners test their water? Annual testing for coliform bacteria and nitrate is essential, with immediate testing after any changes in taste, odor, or appearance. Comprehensive testing every three years should include pH, hardness, iron, and manganese. Our Licensed Well Inspectors evaluate your well’s construction and location to recommend appropriate testing schedules.
Can one system solve all my water problems? Water softeners excel at removing hardness but don’t address iron, low pH, bacteria, or chemical contaminants. Most homes need customized multi-component systems. Professional testing reveals your complete water chemistry so we can design treatment addressing all concerns—not just symptoms.
What’s the difference between LCA water and private well water? Municipal water undergoes professional treatment and monitoring to meet EPA standards, though it may still contain chlorine, hardness, and emerging contaminants. Well water quality depends entirely on local geology and well construction, commonly facing hardness, iron, manganese, and pH challenges. Both sources benefit from appropriate treatment tailored to specific characteristics.
