Water produced during development was discharged to 20-yard bins stationed near each ' well pair. The development water was collected in a vacuum truck and hauled to the on- site water treatment facility for later processing through the Marley/SPX water treatment plant. 8.I Well MW-450D Well MW-450D was developed on July 9, 2012. The initial depth-to-water was measured at 54.62 feet below the top of casing(ft TOC) at 10:30 on July 9,2012. The bottom of the well was measured at 177.35 ft TOC before development. ' The first stage of development included surging and bailing with a 3-gallon bailer. Initially, the bailer was lowered 13 times to remove approximately 40 gallons of water. The first 4 bailers contained mostly drilling mud that settled at the bottom of ' the well. After the 13`h bailer,the well was surged for approximately 15 minutes with a single surge block. The bailer was then lowered 10 additional times with the initial bailers containing some fine sand. The remaining bailers had silty water. Approximately 70 gallons were removed by the bailer. ' The second stage of development included pumping with a 3-inch diameter submersible pump at varying depths in the well. First,the submersible pump was lowered to approximately 15 feet below the water level (approximately 96 feet above ' the top of the well screen). 320 gallons were pumped from the well in 47 minutes at an average rate of approximately 7 gallons per minute(GPM). Turbidity declined from a peak of 930 NTU to 75 NTU (Figure 9). Pumping was stopped and the ' submersible pump lowered to a few inches from the bottom of the well. Pumping resumed with the submersible pump raised gradually over the 10 feet of well screen. An additional 181.6 gallons were pumped from the well with the final turbidity ' measurement at 2.8 NTU. The bottom of well MW-450D was measured at 180.98 ft TOC at the conclusion of ' development. Approximately 3.6 feet of drilling mud and sediment was removed from the well after development. ' 8.2 Well MW-4505 Well MW-450S was developed on July 9 and 10, 2012. The initial depth-to-water was measured at 51.55 ft TOC on July 9, 2012. The bottom of the well was measured ' at 148.20 ft TOC before development. On July 9, 2012 the bailer was lowered 19 times to remove approximately 57 gallons ' of water. The first few bailers contained mostly drilling mud that settled at the bottom of the well. After the 19`h bailer, the well was surged for approximately 15 minutes. The bailer was then lowered 20 additional times. In total, approximately 120 gallons were removed from the well using thebailer on July 9.
