Massachusetts Freshwater Beaches [2020]: Water quality data for public and semi-public beaches The table below summarizes testing and posting information for each freshwater beach in Massachusetts. Under the state regulations, freshwater beaches must test for either E. coli or Enterococci. Most beaches do not have to post after each exceedance, provided that (1) they take an immediate resample and (2) that resample does not exceed the standard. Thus, a beach may have an exceedance but no days posted. Conversely, a beach may have days posted, but no exceedances, if it was posted for a reason other than a bacterial exceedance (e.g. rainfall, a cyanobacterial harmful algae bloom, or another hazard such as limited visibility due to poor water clarity).
