Commissioner Tim Zorc 11:50 1. Additional Water Sampling a.m. (memorandum dated May-10-2016)--------------------------------------------------134-138-- Commissioner Zorc discussed four water sampling collection points in the eastern part of the Indian River Farms Water Control District (IRFWCD) network, where heavy concentrations of nutrient growth have been found. He asked if the Board wanted to undertake an in-depth analysis of those areas to determine the sources of said nutrients; see what additional collection points could be added to track the nutrient loads from the western part of the network continuing east; and have staff report back on the costs of analyzing the four areas currently being sampled, as well as the remainder of IRFWCD's canal network on an ongoing basis. Commissioner O'Bryan suggested that due to the cost, one of the four sites should be selected for a targeted analysis. He also spoke to the importance of installing a rain gauge network. Discussion ensued about using the collection point at 85th Avenue and 8th Street for the analysis, because it is not near a golf course (thought to contribute more nutrients). ON MOTION by Commissioner Zorc, SECONDED by Commissioner O'Bryan, the Board unanimously directed staff to return to the Board with recommendations and costs, for: (1) undertaking an intensive analysis of the 85th Avenue and 8th Street data collection point for water sampling, to acquire more data of the nutrient loading of the canal water that flows to the Indian River Lagoon; (2) analyzing the water flowing from the west to the east to explore any variations in nutrient loads; (3) adding supplementary water sampling locations to the west of the May 10,2016 Page 12 Board of County Commission Minutes
