Portsmouth water remains in compliance with quality requirements for lead
The City of Portsmouth completed its recent round of sampling under the Lead & Copper monitoring program and is pleased to report that the water system remains in compliance with the current lead and copper regulations. This sampling is required by the U.S Environmental Protection Agency (EPA) under the Safe Drinking Water Act (SDWA) and is administered by NH Department of Environmental Services (NHDES) through the Lead and Copper Rule (LCR).
Higher than normal precipitation over the past three months have caused the quantity of available groundwater and surface water to be greater than normal for this time of year. The quality of the surface water has greatly improved and stabilized since the dynamic water quality changes that occurred in late September and October.
On October 1, 2018, Deputy Public Works Director Brian Goetz shared an update on the Pease Tradeport Water System and upgraded PFAS treatment.
Currently, the Water Division started their twice annual routine hydrant flushing of the City’s 190 miles of water mains to remove sediment buildup on Monday, September 17th. Work will not occur on the evenings of September 24th or September 25th.
The City of Portsmouth and the United States Air Force have recently signed their latest agreement to treat perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) from water supplied by the Smith, Harrison and Haven Wells serving the Pease Tradeport drinking water system. The agreement will provide the City with up to $14.3 million to reimburse the cost of construction of the final treatment system for all three wells, which will include a dual filtration system consisting of resin and granular activated carbon filters.
While significant rainfall at the end of July into August was beneficial at the time for Portsmouth’s water supply, the current warm and dry conditions increases water supply demands and places further stress to treat quality issues due to added organics within the water.
While significant rainfall at the end of July into August was beneficial at the time for Portsmouth's water supply, the extreme heat conditions continue to place strain on the City's water system. The ongoing heat increases water supply demands and places further stress to treat quality issues due to added organics within the water. Additionally, the annual precipitation average remains below normal due to the dry spring and the City continues to operate without the support of the Haven Well.
The City of Portsmouth’s Water Division has been named a recipient of the New England Water Works Association’s (NEWWA) Public Communications Award; this award recognizes excellence in communications through comprehensive public outreach materials and programs.
Precipitation events during the last couple weeks of July considerably reduced water demands. As the accompanying information shows, this rainfall also resulted in slightly higher than normal stream flows, reservoir levels and recharge to our water supplies.
