Voluntary Water Restrictions Lifted
Over ten inches of rain fell on the Seacoast area of New Hampshire in July. This amount of rain has significantly reduced the 12-month annual rainfall deficit we had been experiencing so far this year.
he City of Portsmouth took the Haven Well off-line in 2014 after testing revealed the presence of perfluorooctanesulfonic acid (PFOS) chemicals in the water at levels that measured higher than the Environmental Protection Agency’s preliminary health advisory level.
VOLUNTARY WATER RESTRICTIONS CONTINUE
Voluntary Water Restrictions Implemented - The Seacoast area of New Hampshire is currently in Stage 1 of drought conditions with abnormally dry conditions. The current hot and dry weather is also increasing water supply demands.
The City of Portsmouth Department of Public Works Water Division released the latest Water Supply Status Report on May 10, providing an assessment of the water supply quantity and quality available through the Portsmouth Water System. Water use generally increases during the summer months as homeowners start outdoor projects and irrigation. At the same time, the water recharge from rainfall decreases in the summer. Since May 2020, precipitation on the Seacoast was 12 inches, or 28 percent below normal.
Water use restrictions are currently not in effect. Management of our water system has helped reduce water loss due to leaks and increase groundwater levels through the efficient use of our surface water supply.
The City of Portsmouth Department of Public Works will dedicate the new Pease Water Treatment Facility located at 97 Grafton Drive in Portsmouth on Tuesday May 4, 2021 at 10:30 am.
