r <br /> GENESIS ENGINEERING&REDEVELOPMENT <br /> • A flow meter; and <br /> • A ball valve to isolate/connect the extraction system to the NPWS. <br /> 2.3 Monitoring Program <br /> A detailed plan for monitoring the effects of groundwater extraction is discussed in the <br /> sections below. The monitoring plan specifies the types of data to be collected and the <br /> frequency at which the data will be collected. The Sampling and Analytical Plan("SAP") <br /> (Appendix B)provides the details on sampling and analytical procedures. <br /> 2.3.1 Periods of Monitoring <br /> The groundwater extraction system will be operated in four periods: pre-startup, startup, <br /> equilibration, and full system operation as described below. <br /> • The Pre-startup Period will begin with the installation of the extraction wells, and <br /> will end when groundwater extraction begins, during which primarily background <br /> data will be collected. <br /> • The Startup Period will cover approximately the first 3 days of extraction when the <br /> system will be operating for 8-10 hours a day. During this period, the wells will be <br /> pumped individually and together at varying rates optimize system performance with <br /> the objectives of determining maximum pumping rates for the well at the center of the <br /> Site while simultaneously meeting NPWS discharge limits. <br /> • During the Equilibration Period the system operating 24 hours day for approximately <br /> 3 weeks, with some fine tuning of flow rates based on nitrate/TDS concentrations and <br /> drawdown in individual wells. <br /> • During the Full System Operation Period the system will operate 24 hours a day with <br /> only periodic adjustment to pumping rates. <br /> 2.3.2 Types and Frequency of Monitoring Data Collection <br /> The types of data that will be collected during all operational periods include: <br /> 1. Water level measurements in extraction and monitoring wells; <br /> 2. Analysis of nitrate and TDS concentrations will be performed on samples collected <br /> from extraction wells, monitoring wells, the blending tank, the inlet to the NPWS, <br /> and at several points within the NPWS; and <br /> 3. Flow rates from individual wells, into the blending tank, and into the NPWS. <br /> R.F.Land Inc. 7 of 11 <br /> Groundwater Extraction Work Plan <br /> October 2014 <br />
