ATC Associates Inc. <br /> Quality Assurance/Quality Control Plan <br /> Revised March 1998 <br /> 10.0 WELL DEVELOPMENT PROTOCOL <br /> Groundwater monitoring wells will be surged and developed prior to setting the surface seal. <br /> Approximately 10 times the volume of water in the casing will be withdrawn if possible. Casing <br /> volumes will be calculated in the following manner: <br /> ............................ ::::..:::::..: <br /> ... .: <br /> ::::: :»:::;.;:::>::> :;' E7L#�tMi Ss~t# UU !~4D P11 P#PE . <br /> ....;;;: ..:;.:>: <br /> # ila e>rer n ( s ::::..;;<:.;:::.: 1.1�:...( 101 <br /> .;;;;:.:::.:::::< .:.:.:..::::.::.:::::::: ..:.;:.:::<.;::.;::.::::::........::::::::::......;;:::.::::.:.:.......::.:.::.::.;;:.;:. <br /> ::>::»::>::>:.:......:.........::........:::::::::.......................:::::::.::::.::::.::.:::::...:.::::: .::.:::.. ..... ........ .................. <br /> <<:` <br /> 2 2.067 0.17 <br /> 4 4.026 0.66 <br /> VMUME OF OPEN BOREHOLE ANR.A.tiNtjl„AR.SPACE BE..............7VIiI�EAI tA�tNC3.Al�E3� <br /> ................................. ... <br /> ........................................................ .. <br /> €::: . <br /> .... <br /> :.:;. <br /> "ae€>' ..iVoium /Linear .etc >`::;.:,::;::: <'1f'`:1`>::.»>a:::>><;>;»::::>::»: e`......:` `.... <br /> calm ::: :::.::......:...:>i.........:<:.>......... ;>;»>:: ::>:::<:»::>::::>:::>::::::>::::> s ll ::»:::::>::::>::::>::>::::>:::::>f�littE�t at :1 .ate:::>:<:>::;»>::»::>::>:: <br /> »:..:> <br /> :::<::<: <br /> X. <br /> 7.25 2.14 0.29 2 1.91 0.26 <br /> 8.25 2.78 0.37 2 2.55 0.34 <br /> 10.25 4.29 0.57 2 4.06 0.54 <br /> 10.25 4.29 0.57 4 3.46 0.46 <br /> 12.25 6.13 0.82 4 5.30 0.71 <br /> Annular volumes will be multiplied by 30%to account for porosity of filter pack. <br /> If the aquifer is slow to recharge, development will continue until recharge is too slow to practically <br /> continue.
