A DES advisory sign at Pawtuckaway State Beach warns visitors it is unsafe to swim.
'Unsafe' to swim at NH state beach
RAYMOND - The Department of Environmental Services says it may be unsafe to swim at a state beach ahead of the Fourth of July weekend.
Results from recent water testing at the state beach at Pawtuckaway State Park showed elevated levels of E. Coli bacteria.
The E. coli comes from fecal matter, but there is no way to determine how much fecal matter or the source from these tests, according to Beach Program Coordinator Sonya Carlson.
"This is just bacteria from a warm-blooded animal indicating that there's feces in the water," Carlson told NH1 News.
The advisory follows regular testing of 170 freshwater beaches in the state, which are conducted by DES three times throughout the summer.
Warnings are posted on the department's website.
So far, DES says they have issued advisories 5 or 6 times this year, an amount that Carlson says is relatively low.
