——==~ —S — Page 8 of 8 Comparison of a three-year average of the concentrations of Primary and Secondary Drinking Water Standards from the City’s annual compliance monitoring events (circa 2006, 2007, and 2008) to the results from HSA’s November 2008 distribution system tap sampling reveals relative equivalence with irrelevant differences between select parameters concentrations since the averaged City results are less than respective MCLs (see Table 1). With the exception of the occasional spike in concentrations of DBPRs (and corresponding stronger taste of chlorine in the delivered drinking water) resulting from the City’s need to increase the application of sanitizing chemicals (i.e. chlorine) to treat supply water, HSA concludes that the quality of the potable water product delivered to the Town by the City meets or beats the criteria for the standards established under rule 62-550, F.A.C.
