The results presented in this report were created in partnership with City of Santee and the Sage Project during the spring of 2016. Students in Environmental Engineering 363 collected and analyzed water samples from areas of interest within the City of Santee. To address the City of Santee’s plan to offset the pollution load to the San Diego River, samples were analyzed to improve understanding of environmental conditions around areas of interest. This report presents data collected from six different sites for ten different constituents under both wet and dry weather conditions. It com¬pares measured values to the Water Quality Benchmarks from the San Diego River Watershed Management Area Water Quality Improvement Plan to determine whether pollutant concentrations are of concern. Findings are divided by site. Each section begins with a brief description of the site and surrounding areas. Pollutants out of compliance are highlighted, and hypotheses for measured values are provided. Weather conditions and sampling dates are taken into consideration.
