Under Pennsylvania Compliance Reporting, who submits drinking water data?

• A. The facility's customers.
• B. The wastewater facility.
• C. The laboratory on behalf of the drinking water facility.
• D. The state treasurer.

Answer: (C)

In Pennsylvania, the responsibility for submitting drinking water data lies with the certified laboratory that analyzes the samples for a drinking water facility. The lab prepares and reports the test results to the Pennsylvania Department of Environmental Protection (DEP) on behalf of the water system, handling the data quality checks, formatting, and electronic submission. The facility itself collects the samples and ensures the correct tests are performed, but the actual submission to the regulatory agency is done by the laboratory. The other options don’t fit because customers aren’t responsible for reporting, a wastewater facility handles different regulations, and the state treasurer has no role in submitting drinking water data.
