There are a few changes in the monitoring program for the summer of 2010. The indicator organism is enterococcus which complies with US Environmental Protection Agency’s requirements intended to provide one standard for water quality for all ocean and tidal marine bathing beaches in the United States. The maximum estimated enterococcus bacteria in marine waters shall not exceed 104 per 100ml of sample. Two consecutive counts of 104 per 100ml at a sampling site constitute a closing. Additionally, only designated recreational bathing sites are being tested this year.
A total of fifty-nine (59) ocean and eight (8) Back Bay recreational sites have been selected for weekly monitoring. Testing of recreational sites will begin on May 17th and continue through September 6, 2010.
