Despite the cool and wet weather pattern we have been experiencing in Southern New Hampshire, this area continues to have below normal precipitation. Precipitation since December 2018 is only 65% of normal. However, the cooler weather has resulted in lower than normal irrigation and water demands in our system. Therefore, there are currently no water restrictions in place. 

The City of Portsmouth’s water supply staff continue to monitor all of our public water supply sources for Perfluorinated compounds (PFAS) every six months. The following report details the most recent analysis of the Portsmouth supply sources taken in April 2019. The water samples for this round were analyzed using the detection limits proposed by the New Hampshire Department of Environmental Services (NHDS) as part of the rulemaking process to set Maximum Contaminant Levels (MCLs) for four PFAS compounds.
