stresses associated with operation of the facility. This testing was performed in July, September and October of 2013. During these tests, IRCDUS was not made aware of any interferences reported from the Van Antwerps. During the period of December 20 to 23, 2015, NCRO was forced to increase production to full capacity to take on demand from the entire county while the South County Reverse Osmosis (SCRO) WTF was offline for repairs due to an emergency break. During the three days SCRO was not operating, seven of the nine production wells at NCRO ran approximately 16 hours a day, with four of the nine wells running the remaining eight hours per day. No interferences were reported from the Van Antwerps. As part of the NCRO on-going UFA well monitoring program, on April 10, 2017, IRCDUS conducted the first quarterly UFA well sampling under the CDM Smith, Inc., work order. As part of the testing, County increased production at the NCRO to full capacity, pumping from seven to eight of the nine production wells for 1.5 hours, to represent full aquifer stresses associated with operation of the facility. During the subject testing, Mr. Van Antwerp reported loss of artesian flow at 1 of his wells (Well No. 1). He could still pump water from his wells, but the artesian pressure dropped as a result of a dry April and the functional test of the IRCDUS wells. Mr. Van Antwerp was again concerned about his upcoming planting season (July 2017), and the Director of IRCDUS discussed options with him on how best to alleviate those concerns. A centrifugal pump at Well No. 5 (the western well on the VA property - see Attachment 1) was rented by IRCDUS and affixed to the well. Piping was installed by IRCDUS to provide flexibility to fill Mr. Van Antwerp's canals so that he could use his mobile irrigation spray device. Mr. Van Antwerp could either use flow water from artesian pressure or run the rented pump. The rented pump at Well No. 5 has been in place and paid for by IRCDUS since June 2017. As part of the ongoing discussions with the Van Antwerps and SJRWMD, IRCDUS was asked to make the Van Antwerps "whole". Since historical water quantity and quality records did not exist for the VA wells, IRCDUS was in a difficult position of trying to effectively find a solution while not knowing what the end target was. Additional expertise was needed to help provide current data that would identify existing conditions at the VA properties and to help craft a more long-term solution for IRCDUS and the Van Antwerps. In May 2017, the BCC authorized Kimley Horn and Associates (KHA), in conjunction with hydrogeologist firm JLA Geosciences (JLA), to collect data in order to assess what was happening at the VA's wellfield while the County was drawing water from the UFA. With Mr. and Mrs. Van Antwerp's permission, calibrated testing equipment was strategically located at four of the Van Antwerp wells. Recording devices were able to precisely track the drawdown effects on the VA wells when IRCDUS wells were operating. Specific tests were performed, such as pumping a set of eastern IRCDUS wells at one time, then switching to a group of western wells. Additionally, a test was run that involved pumping a majority of wells in an effort to gauge the varying degree of drawdown experienced at the VA wells. A final test was conducted in which none of the NCRO wells were operated. As a result of the test, artesian pressure was restored, but only briefly to the VA wells, as it was discovered that other, non -county users of the UFA were causing adverse drawdowns on the VA wells. In short, the report documented how the IRCDUS affected the VA wells under certain pumping conditions, but it also identified the fact that other unidentified users of the UFA are also impacting the VA wells. The JLA report was furnished to the District. The Van Antwerps, recallingthat a formal agreement never came to fruition in 2012, and with 2017 testing issues reigniting concerns, requested a more formal mitigation plan be put in place. Staff began to explore options of potential solutions based on the data obtained from the hydrogeologist. 153 Page 3 of 7 C:\Users\legistar\AppData\Local\Temp\BCL Technologies\easyPDF 8\@BCL@ACODF439\@BCL@ACODF439.docx
