About Northampton
Set along the Lehigh River in the heart of the Lehigh Valley, Northampton is minutes from Bethlehem and Allentown and proudly reflects its cement-industry heritage. Local landmarks include the National Museum of Industrial History, the SteelStacks campus in nearby Bethlehem, and the borough’s own Atlas Cement legacy. Public drinking water in the borough is provided by the Northampton Borough Municipal Authority (NBMA), with treatment performed at NBMA’s plant; some surrounding homes in the region may also rely on private wells. (Primary ZIP mentioned once: 18067.)
Water Quality & Plumbing Issues in Northampton
- Hard water (scale buildup): Mineral scale can spot fixtures and reduce appliance life. Solution: High-efficiency softening / conditioning.
- Hydrogen sulfide (rotten-egg odor): Common in private wells; affects taste and smell. Solution: Air-injection iron & sulfur filtration.
- PFAS / lead concerns: Targeted point-of-use filtration helps reduce specific contaminants reported across the region. Solution: Reverse osmosis drinking water systems.
- Low water pressure / aging plumbing: Older piping and well system components can cause pressure issues. Solution: Well tank & pump services and code-compliant plumbing upgrades.
