' Suraing: Care will be exercised when using a surge block to avoid <br /> damaging the well screen and casing. When surging wells screened <br /> in coarse (sand/gravelly) aquifers, the rate of surge block <br /> lifting shall be slow and constant. When surging wells screened <br /> in fine (silty) aquifers, more vigorous lifting may be required. <br /> Between surging episodes, wells will be bailed to remove <br /> accumulated sediments. <br /> Pumping: Development pumping rates shall be less than the <br /> recharge rate of the well in order to avoid dewatering. <br /> Discharged Water Containment and Disposal: All water and <br /> sediment generated by well development shall be collected in 55- <br /> gallon steel drums. Development water will be temporarily <br /> contained on site, pending sampling and laboratory analysis. No <br /> hazardous development water will be released to the environment. <br /> Disposal of development water will be the responsibility of the <br /> client <br /> 1 <br /> 1 I r <br /> 1 <br /> I <br /> I I 1 <br /> JI <br /> I <br /> I I <br />
