Health officials in the town of Sandown, New Hampshire, have closed a public beach due to abnormally high counts of cyanobacteria cells in the water.
Local officials say Seeley Beach in Sandown is closed until further notice after water samples taken on Monday by the state Department of Environmental Services tested with organisms capable of producing toxins. Further testing will be conducted.
Seeley Beach participates in the N.H. Beach Program which monitors water from 193 beaches for fecal bacteria. From 2003 to 2013, the water at the beach has been tested 76 times with one sample above state standards. From 2003 to 2012, there have been two cyanobacteria advisories issued.
