Attachment 2 (Water -CAT Active Monitoring Location Map) identifies the 'active monitoring sites' in and around Blue Cypress Lake. This map was created through the University of South Florida's Water -CAT database (The Florida Water Resource Monitoring Catalog) and defines 'active monitoring sites' as sites that have had monitoring activity within the past four years. This map does show a significant reduction in the monitored sites when compared to the STORET map of sites, although the 'active' sites do reflect targeted coverage of the Blue Cypress Lake and immediate surroundings. Site monitoring requirements on the FDEP-permitted Biosolids Land Application sites are.minimal and self- reported. Soil fertility testing is to be performed in accordance with the site's Nutrient Management Plan at a frequency of at least once every five years, and site pH testing to be conducted annually. No site-specific data was located at the time of this report. The occurrences of algae blooms in water bodies has a strong correlation to elevated levels of nutrients found in those water bodies. The FDEP has created and maintains an Algal Bloom Sampling Results interactive webpage (Attachment 3) in which results from algae sampling activities are stored. Between the FDEP and SJRWMD, results from recent algal monitoring activities on and around Blue Cypress Lake are made available to the public. With the various regulatory agencies having vast amounts of historical data, and with some of those same agencies still having active monitoring plans in place in and/or around Blue Cypress Lake, evaluations by their experts on the data may be used to drive future monitoring programs. Advances in testing techniques have brought forth analytes that can be used to track anthropogenic influences. When the regulatory agencies review their sampling plans and results, perhaps they can include tests. such as Sucralose, Caffeine, Acetaminophen or Nitrogen isotopes in an attempt to identify sources of any elevated results that they may find. RECOMMENDATION: Staff recommends that we continue to observe the monitoring programs in place from the Florida Department of Environmental Protection and the St Johns River Water Management District and inquire about them adding anthropogenic marker tests to their routine sampling should the data point to an increased nutrient loading in the area.
