Certified Testing and Compliance for Pennsylvania’s Regulated Water Systems
At Princeton Analytical Labs, we provide state-certified testing and compliance support for all types of Public Drinking Water Systems (PWS) throughout Pennsylvania. Whether your system is municipal, community-owned, or privately operated, our goal is the same — to ensure your water consistently meets DEP and EPA safety standards under 25 Pa. Code Chapter 109 and the Safe Drinking Water Act.
Understanding Public vs. Municipal Water
While the terms are often used interchangeably, they have distinct meanings under Pennsylvania law:
- Municipal Water Systems are owned or operated by a city, township, or borough authority, typically serving homes and businesses within a defined service area.
- Public Drinking Water Systems include all systems that serve 25 or more people or have at least 15 service connections, even if privately owned — such as schools, mobile-home parks, apartment complexes, churches, and campgrounds.
Both must comply with the same testing and reporting requirements established by the Pennsylvania Department of Environmental Protection (DEP). Princeton Analytical Labs supports both categories with equal reliability and precision.
Our Public Drinking Water Services Include
- Routine Bacteriological Monitoring
Monthly or more frequent testing for total coliform and E. coli at representative sites throughout the system, per DEP sampling schedules. - Chemical and Physical Analysis
