Abstract/Description:
Water quality problems can arise from excess nutrients and other chemicals. The problematic chemicals may be from septic tanks, surface applications on lawns and agricultural fields, or insufficient waste water treatment practices. The community of San Carlos Park, Lee County Florida provides a good model to examine potential sources and fates of these chemicals. The community has over 6000 residences, over 90% of which are using septic tanks for wastewater treatment. We are examining whether there is a measurable presence of chemical of emerging concern (as an indicator of presence of human impact), in addition to water quality parameters, in the surface waters along the East Mulloch Drainage District. Nutrients were analyzed at Lee County Hyacinth Control Lab using an automatic analyzer (AQ2 by Seal Analytical) and chemicals including sucralose were analyzed at FIU Southeast Environmental Center using solid phase extraction liquid chromatography. Atrazine, simazine, propazine, and cyanazine were analyzed at FGCU. A comparative analysis was conducted using the results of the samples collected in March 2017 and September 2017, which allowed us to see if there were problematic chemicals in the surface waters of the East Mulloch Drainage District, in San Carlos Park Florida. Our results indicate that sucralose was found in all seven samples we took in March of 2017. Our results also showed that there were significant differences in ammonia, total nitrogen, and nitrate/nitrite levels between March 2017 and September 2017. However, there were no levels of any nutrient that were above the EPA’s acceptable contaminant levels, and the differences observed can be attributed to seasonality.
