About this file

Written by GovTribe AI ·

This file is a Public Drinking Water System Report for the UNH/Durham Water System located at 28 Water Works Road, Durham, New Hampshire, operated by the Town of Durham in conjunction with the University of New Hampshire. The system is an active, major community water system classified as serving a population of 16,000 people through 1,250 service connections. The report contains comprehensive water quality monitoring data documenting lead and copper 90th percentile compliance testing conducted on an annual basis since 2014, with historical data extending back to 1992. The system maintains an extensive sampling program with 3,874 documented samples processed by laboratories including Seacoast Analytical Services LLC, Granite State Analytical Services LLC, and New Hampshire DHHS Public Health Laboratories. Water quality samples have been collected from multiple distribution points across the service area including university facilities, town buildings, and residential locations, with sampling types including Total Coliform Rule compliance testing, disinfection byproduct monitoring, lead and copper rule compliance, chemical monitoring, and general system evaluation samples collected throughout 2025 and early 2026.

The primary operator is Woodard and Curran with Michael Sullivan as the contact, while the owner's representative is April Talon from the Town of Durham Public Works Department. Lead and copper levels have consistently remained well below regulatory action levels across all monitoring rounds, with the most recent 90th percentile calculations from January 2026 showing lead at 0 mg/L and copper at 0.177 mg/L. The system maintains active compliance with federal Safe Drinking Water Act requirements through regular monitoring at Seacoast Analytical Services LLC, the primary certified laboratory serving the system, and periodic general system evaluation samples analyzed by New Hampshire DHHS Public Health Laboratories and Eurofins Portsmouth.
