SECTIONFIVE Slug Test <br />' A slug test was conducted at monitoring well GW-5 to estimate the hydraulic conductivity of the <br />Troublesome Formation. This well penetrates, and is screened within, the Troublesome <br />' Formation from 48 to 58 feet bgs. The test was conducted by lowering a 1.5-inch wide by 5-foot <br />long sealed tube (slug) into the well and measuring water level response. Water levels were <br />recorded continuously using a pressure transducer and data logger. Results of the slag test aze <br />' presented in Figure 7. <br />Prior to initiation of the test, static water level within GW-5 was measured at 33.76 feet bgs. <br />' Insertion of the slug caused slightly less than a foot of water level rise within the well casing. <br />Water level within the well recovered to within 0.01 feet of static within 1 minute after insertion <br />of the slug. The slug test data were analyzed using the Bouwer and Rice (1976) method, which <br />yielded a hydraulic conductivity of approximately 3 ft/d. However, caution must be used when <br />interpreting these data due to the limited water level rise induced in the well, the rapid recovery, <br />and the general uncertainties inherent in slug tests. <br /> <br />1 <br /> <br /> <br /> <br />1 <br /> <br /> <br />1 <br />1 <br /> <br />~~` 1\SOMINIFLEI~EIMPHGIECfS614501_NQOERSON_YM1~FEA4151A OQlO Piq.1_OF1NJiENSm TECN MEM6H1.000~1l19111E PM S-I <br /> <br />
