The research primary goal was to identify and evaluate anthropogenic pollution sources affecting bathing zones water quality of Puerto Rico. Three sources were identified: 1) wastewater-septic wells, 2) adjacent surface water bodies, and 3) storm water discharge. A pilot study was performed on 23 Beaches analyzing eight (8) years of microbiological data to evaluate compliance. The pilot project results indicate higher violation to enterococci parameter than to fecal coliform. Enterococci survive more than fecal coliforms under environmental conditions and are better microbiological water quality indicator. This implicates the possibility of human health risk since pathogens may be present.

520 $a The research primary goal was to identify and evaluate anthropogenic pollution sources affecting bathing zones water quality of Puerto Rico. Three sources were identified: 1) wastewater-septic wells, 2) adjacent surface water bodies, and 3) storm water discharge. A pilot study was performed on 23 Beaches analyzing eight (8) years of microbiological data to evaluate compliance. The pilot project results indicate higher violation to enterococci parameter than to fecal coliform. Enterococci survive more than fecal coliforms under environmental conditions and are better microbiological water quality indicator. This implicates the possibility of human health risk since pathogens may be present.
520 $a Fecal coliform, enterococci, Biochemical Oxygen Demand, (BOD5), dissolved oxygen, salinity, temperature, pH and caffeine analysis, were performed monthly to correlate with pollution sources during one year. A 2 x 6 Factorial Sampling Design was used as a guide for data collection. Descriptive statistic was used to present the data and MiniTab statistical software to analyze it. Correlation was used to evaluate caffeine concentration relationship with microbiological water quality compliance (r=1 and p<0.05).
520 $a Relationships between the parameters and enterococci suggested a strongly correlation at the representative beaches (r=0.975; p=0.000). Results also indicate that enterococci are better water quality indicator for tropical water (r=0.898; p=0.000).Caffeine presence established wastewater-septic tanks and storm water discharge representatives as the more affected by anthropogenic influence.
520 $a The presence of caffeine on samples in compliance to standards suggests the location of treated water discharges. Correlation analysis at all the representative beaches indicate that a change in normal pH is strongly correlated with the presence of caffeine in water samples (r=998; p=0.000).
520 $a This dissertation research corroborates the use of caffeine as an indicator of anthropogenic pollution source of beach tropical waters samples in Puerto Rico. It uses, as water quality parameter, will be an innovative and cost effective analysis to evaluate anthropogenic pollution sources and preserve aquatic environments. These results are consistent with caffeine detected in tropical beaches with urban influence on a study performed in Hawaii. This is the first study performed in Puerto Rico, In the Tropical Atlantic Zone and the second in tropical waters.
