Once installed, all new <br /> wells shall be added to the monitoring program and shall be sampled and analyzed according to <br /> the schedule below. <br /> GROUNDWATER MONITORING <br /> As shown on Figure 1, there are 10 groundwater monitoring wells at the site. Five monitoring <br /> wells are in the shallow water-bearing zone (MW-IA through MW-5A) and five monitoring <br /> wells are in the intermediate zone (MW-IB through MW-5B). The groundwater monitoring <br /> program for the 10 monitoring wells, and any wells installed subsequent to the issuance of this <br /> MRP, shall follow the schedule below.
