s <br /> J <br /> Pump test data will be evaluated using methods appropriate for It'he aquifer type. <br /> w. Hydraulic conductivity, transmissivity and stor tivity (or spec°r:c yield) will be <br /> calculated. Calculations used for the derivation of these values W_ l be provided, as <br /> well as figures showing the measured drawdown and calculated ca- ture zone. Field <br /> data will also be reduced and presented in tabular form in the final report of testing. <br /> Procedural details are presented in the Aquifer TeE t Protocols (Appendix B). <br /> 1 . <br /> 5.2 Vapor Extraction Test <br /> Vapor extraction testing will be conducted ir. accordance with the protocols <br /> provided in Appendix C. It is anticipated that the extraction test will be conducted <br /> using a 3/4 Horsepower regenerative blower, ith extracted soil vapor removed <br /> from the effluent air stream by means of granular activated c _-'::on in. 55 gallon <br /> containers connected in series. I <br /> i <br /> The testing will be conducted using wells VW- and VW-2 as extraction points.. <br /> Vapors will be extracted from each in accordance with the attached protocols for a <br /> period of approximately three hours each. Mord-.oring wells MW-2 and MW-7, the <br /> pump test well, and VW-3 will be utilized as monitoring points during each vapor j <br /> extraction test. <br /> 5.3 Air Sparging Test <br /> The air sparging test will be performed by applying air pressure to -:_Le sparging wells <br /> by means of an air compressor or blower. The flow of air from the sparge wells will i <br /> be monitored to determine it's extent and effect on the surrounding formation and <br /> ground water. The test will be performed at diff rent levels of applied air pressure. <br /> The applied air pressure will be changed when the pressare influence in <br /> surrounding wells stabilizes. The initial applied air pressure Nvill be 10 psig. The <br /> k _ applied air pressure will not exceed 45 psig, the PVC pressure limi The injected air <br /> r pressure will not exceed 45 psi to provide a saf ty factor to prevent rupture of the <br /> well screen, and the flowrate will not exceed 60 c <br /> Prior to beginning the test, the following m asuremenls w _` be -made at the <br /> surrounding observation wells: <br /> • Depth to water will be measured to thenearest 0.01 foo`_ with a Solinst i <br /> Felectronic interface probe, or equivalent. <br /> • Dissolved oxygen (DO) content of the well ater will be meas--red. <br /> F <br /> F <br /> F <br /> D-207/FTLOT TEST WP 5 <br /> F <br />
