He <br />recalled that subsequent to the Board's approval in December 2012, ORCA had installed Kilroy <br />monitors to monitor the amount of flow and nitrogen discharged into the Indian River Lagoon <br />from the North, South, and Main Relief Canals. He revealed that the County had taken some <br />"grab water samples" and that an inconsistency had been discovered as far as the flow and the <br />dissolved nitrates between the Kilroy and the grab sample readings. Director Mora advised that <br />ORCA has advised that adjustments can be made to obtain good data in the future. <br />Warren Falls, Managing Director, introduced the ORCA representatives who were in <br />attendance: Edie Widder CEO; George Jones, Special Projects Director; and Robin <br />Dannahower, Vice President Marketing and Public Relations. Through a PowerPoint <br />presentation, he explained that the inconsistencies mentioned by Director Mora were mainly due <br />to silting, water clarity issues, and the bromide levels that were found in the canals. He <br />described how ORCA will be able to reconstruct the algorithm of the equipment and start post- <br />processing the data to bring the information back into line, and said ORCA will begin reporting <br />March 4, 2014 19 <br />
