r Id <br /> Tr <br /> u <br /> r <br /> APPENDIX F: PUMP TESTING PROTOCOLS (continued ) <br /> A 2-4 HP submersible pump will be used for the aquifer testing . Flow <br /> rates will be controlled and measured by devices such as orifice <br /> �s <br /> valves . Pumping rates will be measured with in-line totalizers and <br /> pressure operated flowl-rate gauges . Water levels during pump tests <br /> will be measured in the pumping well and observation wells using <br /> calibrated pressure transducers and a data logger. During the pump <br /> tests , water levels wijll be measured beginning at regular intervals <br /> f increasing until a five-minute interval has been reached , and at <br /> five-minute intervals !thereafter. Water levels will be recorded in a <br /> well outside the expected area of influence of the pump test to detect <br /> outside influences on „water levels . <br /> �9 <br /> k Water generated by the aquifer tests will be stored on site in steel <br /> I <br /> tanks . It will then be treated by the existing on-site air stripper:. <br /> and discharged into an. on-site disposal pond . Should prolonged <br /> aquifer tests prove to be difficult due to the amount of contaminated <br /> water produced , slug tests on existing monitoring wells could be used <br /> to generate data on the aquifers ` hydraulic parameters . <br /> f <br />
