If <br /> a dedicated in-situ pump system is utilized to collect the sample,the filter shall be connected to <br /> the discharge tubing allowing the pump pressure to force the sample through the filter." <br /> 8. Section 3.4,51 paragraph,please provide a statement about how the filter will be purge or rinsed <br /> prior to sample collection. <br /> The following statement has been added to Section 3.4,a paragraph:'The new filter cartridge <br /> shall be purged with sample water by the method described previously,allowing time to observe <br /> proper function of the filter demonstrating clear water production prior to filling the subject <br /> sample bottle(s)." <br /> 9.

If a bottle is overflowed,the bottle shall be discarded <br /> and an identical replacement pre-preserved sample bottle will be substituted from spare bottle <br /> set inventory,kept on hand for such occurrences." <br /> 10. Section 3.4, 6 h paragraph,please commit to submitting a technical revision if a dedicated pump <br /> system is to be installed in any of the current or future groundwater monitoring wells. <br />
