Elizabethtown Water Hardness & Quality Report (2026)

The Elizabethtown Area Water Authority provides water to around 19,000 residents in Elizabethtown and nearby areas of Lancaster County, Pennsylvania. Their water supply comes from surface water sources within the Susquehanna River watershed. This water is treated at the facility located at 211 W. Hummelstown St., Elizabethtown, PA 17022. You can reach them at 717-367-7448 or via email at EAWA@etown-water.com. The authority regularly publishes Consumer Confidence Reports, outlining their adherence to EPA standards. Treatment at the plant involves standard surface water processes, including coagulation, filtration, and disinfection.

The region's geology is characterized by Paleozoic sedimentary rock formations, part of the Appalachian geologic province. These include Devonian-age Keyser and Helderberg limestones, along with Mississippian-age Pocono sandstones and shales found across Lancaster County. This landscape is known for its karst terrain. As water travels through these carbonate-rich formations and limestone aquifers, it picks up dissolved calcium and magnesium ions, resulting in water that is typically hard, a common trait for central Pennsylvania's water.

Homeowners often notice scale buildup in pipes, water heaters, dishwashers, and washing machines due to this hard water, which can reduce appliance efficiency and shorten their lifespan. A common sign is the white residue, often calcium carbonate, that appears on fixtures and dishes and fizzes when treated with vinegar. To combat this, regular cleaning of aerators and heaters is advised, and installing a water softener is highly recommended to protect appliances and improve how effectively soap lathers. EAWA also reported that in recent consumer confidence reports, four contaminants were found above EPA health guidelines, with two MCL violations.
