Home My WebLink About2006-135 ATTACHMENT A aooG SCOPE OF WORK INDIAN RIVER COUNTY WATER QUALITY SAMPLING DURING THE NORTH COUNTY WATER TREATMENT PLANT EXPANSION BACKGROUND The Indian River County (County) Soil and Water Conservation District (SWCD) has recently expressed concerns to the County over the pending North County Water Treatment Plant (WTP) expansion project. The concerns focus on the neighboring land owners around the WTP site. To the west of the WTP (upgradient), there are several functioning citrus groves, a number of ranchettes (former citrus groves), and several smaller residential sites. Many of these properties continue to utilize the artesian flow wells that were installed by the original citrus farmers for both irrigation and potable use. The SWCD is concerned that once the County installs and places in to operation the additional six supply wells needed for the expansion project, the artesian wells will cease to flow and may require the use of pumps to continue to be of service to the owners. While hydraulic modeling performed by both consulting engineers and the St. Johns River Water Management District (SJRWMC) indicate that drawdown from the additional wells will likely not negatively impact the neighboring wells, the County has agreed to conduct monitoring of the wells to establish baseline data prior to the project completion. The County proposes to sample the neighbors' wells for water level, chlorides, pH and dissolved oxygen during the bidding and construction phases of the expansion project. It is anticipated that this period of monitoring will result in approximately 24 months of background data. This data will provide a baseline against which to compare data after start-up of the expanded facilities . This will allow the County to quantify the impacts, if any, of the additional withdrawals. Services to be provided under this authorization are provided below. SCOPE OF SERVICES CDM will perform the following task services associated with the sampling/ monitoring program. Task 1. 0 Acquisition of Necessary Field Equipment CDM will purchase the necessary field equipment to perform the required sampling. Equipment to be purchased will include a 500-foot water level probe; a combination chloride, dissolved oxygen, conductivity, and temperature water quality monitor and probe; and a pressure gauge with a range of 0 to 100 psi (for measuring artesian flow) . Upon completion of the project, the purchased equipment will be provided to the County to retain for any future sampling/ monitoring. A-1 mh2440Aoc Task 2. 0 Coordination with Property Owners CDM will meet with SWCD board members to identify the wells to be monitored (approximately 14 wells) . Once identified, CDM will coordinate with property owners to obtain permission to sample the wells on a monthly basis for approximately 24 months. CDM will also schedule sampling events with each owner and provide notice on a monthly basis in advance of sampling. Task 3. 0 Sampling CDM will sample the 14 private wells, the 3 County production wells, and the 3 County monitoring wells on approximately the same day each month throughout completion of the construction phase of the expansion project (approximately 24 months) . It is anticipated that all wells/ parameters can be sampled in a single day each month (approximately 8 hours) . Task 4. 0 Data Summary and Presentation CDM will establish a database and tabulate the monthly data gathered. Upon completion of the monitoring program, CDM will provide the County with trends of the sampled parameters and water levels, identify any adverse trends, and provide suggested further monitoring as the expansion project is placed into service. CDM will compile a letter report to include the data and trends and provide five copies of the letter report to the County . OTHER SERVICES NOT INCLUDED IN THIS SCOPE OF SERVICES CDM intends to rely solely on the accuracy of the field probes for parameter measurements. CDM will not contract with a laboratory for further analysis. If laboratory analysis is required, CDM will negotiate additional services and budget with the County . This authorization does not include: ■ Monitoring services after the expansion is complete and the new facilities are on line ■ Recommendations for mitigation if the new facilities are found to adversely impact neighboring users ■ Permit modifications or negotiations with SJRWMD regarding mitigation COUNTY RESPONSIBILITIES The County will assist in gaining permission to sample any and all County-owned wells included in the monitoring program. This will include on and off site raw water supply wells, on and off site WTP monitoring wells, and any wells located on County-owned property such as golf courses and fairgrounds.
