EXHIBIT A <br /> SCOPE OF WORK <br /> INDIAN RIVER COUNTY <br /> FLORIDAN AQUIFER WELL MONITORING PROGRAM <br /> Background <br /> In April 2006 , the Indian River County (County) Board of County Commissioners authorized CDM <br /> Smith to conduct a well sampling program to establish baseline operating conditions for a series of <br /> 14 Upper Floridan Aquifer wells ( privately owned ) that surround the North County WTP . The <br /> intent was to monitor well capacity and water quality (via water level measurements , pressure <br /> readings and chloride levels ) to establish a database against which to compare similar <br /> characteristics once construction of the North County WTP expansion project was completed . <br /> The County' s Consumptive Use Permit ( CUP ) issued by St. Johns River Water Management District <br /> (SJ RWM D ) mandates that the County' s increased use at the WTP not result in negative impacts to <br /> existing legal users of the same aquifer . A negative impact is quantified by a greater than 10 percent <br /> decrease in flow or a 10 percent change in water quality ( SJRWMD ' s " 10 Percent" rule ) . In this case , <br /> any existing user of the aquifer that can demonstrate that their artesian wells are not artesian when <br /> the WTP is pumping, that their well pumps cannot maintain suction , that their chloride levels (i . e . <br /> saltwater intrusion ) are rising, etc . can approach the County and / or SJRWMD and request <br /> mitigation for the impact. The services to be provided in this Work Order will assist the County in <br /> evaluating any impact claims by neighboring property owners and aid in resolving potential issues <br /> or concerns . <br /> Services to be provided under this authorization are provided below . <br /> SCOPE OF SERVICES <br /> CDM Smith will perform the following task services associated with the sampling/ monitoring <br /> program . <br /> TASK 1 . 0 COORDINATION WITH PROPERTY OWNERS <br /> CDM Smith will contact the property owners of the wells used in the previous sampling program to <br /> re - establish permission to access the wells for further monitoring. CDM Smith will also revisit all <br /> wells for which access is approved and review the wellhead condition to insure that no changes <br /> have been made in the 2 years since sampling was suspended that would prohibit sampling . <br /> Modifications to the wellheads , if necessary, will be negotiated under separate cover and no <br /> provisions are made herein to make such modifications . <br /> TASK 2. 0 SAMPLING <br /> CDM Smith will commence monthly sampling on all of the private wells for which permission to <br /> access has been granted . New wells may be added to the program to replace those that are no <br /> longer in service or not accessible , including additional wells from property owners that have <br /> voiced impact concerns (if any) . It is anticipated that all wells / parameters can be sampled in a <br /> single day each month ( approximately 8 hours ) . <br /> TASK 3. 0 DATA SUMMARY AND PRESENTATION <br /> CDM Smith will add collected data to the existing database that was established during the original <br /> sampling program . Data will be correlated to pumping conditions at the WTP at varying production <br /> A- 1 Asses wo doc <br />
