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 Approximately 10 times the volume of water in the casing will be withdrawn if possible.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 /> SCI4 46�PVC:.PIPE.. <br /> -::.s................. <br /> OLUMEOF' Ep�q ....... <br /> ........... <br /> .... ........ <br /> ......... ........................... <br /> Gallffiiearf� <br /> 2 2.067 0.17 <br /> 4 4.026 0.66 <br /> ........ .... ......... <br /> YdLUME OF OPEN BOREHOLE AND ANNU R SPp►CE BETWEEN CASING AND <br /> HOLE <br /> Hole <br /> . ....... ......................... <br /> ........... <br /> ............ ........ <br /> ........... 6ume:Jn..ea..r..:.FI.:.ee.t. f: <br /> Hole <br /> 6....1..0.....4.. <br /> ............. <br /> .............. <br /> ..I...qi...m. eI L i n'ear: <br /> Feet b V <br /> lame.a <br /> t r.- <br /> asing Annular Space <br /> .......... <br /> 0,600 iame <br /> 'ER t ..................... <br /> .eu. <br /> ........... .......... <br /> ........... <br /> .......... <br /> vjji6he <br /> GailonsF ............... <br /> 'Cubic.,Feet <br /> Gallons Cubic Feet I; <br /> ........... <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 porus tly of fitter pack. <br /> If the aquifer is slow to recharge, development will continue until recharge is too slow to practically <br /> continue.
