EXHIBIT 1 <br /> SCOPE OF WORK <br /> INDIAN RIVER COUNTY <br /> NORTH AND SOUTH COUNTY WATER TREATMENT PLANTS <br /> WELL/ WELLFIELD MAINTENANCE AND MANAGEMENT SERVICES <br /> Background <br /> The Indian River County (County) Department of Utility Services operates two reverse osmosis <br /> water treatment plants (WTP) , which treat water supplied from the Upper Floridan Aquifer <br /> (UFA) . Raw water from the UFA is currently supplied to the North and South County WTPs <br /> from a total of nine supply wells (three at the North County WTP and six at the South County <br /> WTP) . There is also a series of monitoring wells located at each WTP. <br /> Over the past eight years, the South County WTP wells have undergone two phases of <br /> substantial rehabilitation to replace piping, reconfigure the well heads, remove blockages in the <br /> open hole portion of the wells, refurbish pumps/ motors, and replace instrumentation in order <br /> to improve productivity of the wells (measured as specific capacity) and increase operability <br /> through the addition of instrumentation not previously installed. During the rehabilitation, the <br /> wells were videotaped to identify potential physical obstructions that may have been <br /> contributing to the decreasing capacity of the wells. However, the North County WTP wells <br /> have not been videotaped or serviced since their installation in 1996 . Additionally, none of the <br /> County' s monitoring wells have received any significant maintenance in the past several years . <br /> In taking a pro-active approach, the County has requested the services of CDM to prepare a <br /> wellfield maintenance program for the nine UFA wells and all monitoring wells to include <br /> scheduling of maintenance activities over the next several years . The recommended <br /> maintenance activities and the scheduled intervals for those activities will also apply to the <br /> proposed six new UFA wells being constructed as part of the current North County WTP <br /> expansion project. Additionally, CDM will provide assistance in negotiating and executing a <br /> maintenance contract by piggy-backing the existing contract in place with another utility. The <br /> contractor will address any operational issues that arise with the production/ monitoring wells <br /> and provide oversight services for the identified maintenance activities over the life of the <br /> contract. <br /> Services to be provided under this authorization are provided below . <br /> SCOPE OF SERVICES <br /> CDM will perform the following task services . <br /> TASK 1 . 0 STRATEGY MEETING <br /> CDM will meet with County staff to establish the current operating condition of each well, <br /> identify operational issues that may exist for any/ all of the wells, and prioritize the need to <br /> rehabilitate the wells based on their condition. This information will be used to prepare the well <br /> maintenance program plan detailed in Task 2. 0 . <br /> A-1 jb1800.doc <br />
