It is nearly impossible to correct acrd account for the cross flow contmrin~auon firm the sampling intervals by praging large volrmes of borehole fluids. In a similar open bolo ceae in the Piceance Basin, hundreds of gallons per mimtte was measured entering the Disaotutiat Surface Aquifer flour the overlying A and B Groove Aquifers, As a result of casing acrd eementing the overlying aquifers before penetrating the Dissolution Surface Aquifer, AmerAlia gained nearly vugm water quality samples as the sio-only dulling method penetrated the sampling interval vvhoreby lining Sash cuttings and fonoation water to the surface. 13us, high quality ssrnpling mtesval confirmation and water sampling was achieved during both the drilling and completion of each of those wells along with the following moruhly sampling event. these Dissolution Surface Aquifer waters are not frt for human, agriculhual or animal consumption. 7]tis water kills plains and poisons the soil if released to the ground 'Ihe nearest approved disposal site for this water is 90 miles away. User of a disposal site for redrmdant groundwater sampling is both costly and contrary to responsible managemerrt. Beat management practices would be those practices which avoid the environmental camsegaences and liability of exposure of unnecessazy waste prodoaioa, nnnsportation, end disposal of such fluids. A single well bore purge avem for either of these wills produces approximately 2,300 gallons of fluid Without factoring in the high TDS and elevated specific gravity, water produced during a single purge event for both wells exceeds the cxQaairy of a water truck. AmerAlia does not endorse the low volume aquifer monitoring well sampling technique. 1'he historical and ongoing sampling problems and miss-information generated by low volmne well sampling techniques ate well doatmented in the Piceance Basis AmerAlia believes s high quality monitoring well drilling and completion technique followed by high volume sampling supercedes hrmdrods of micro Purged sampling events of poorly or questionably ooastructed momtaring walls. AmerAlia Hoots that WRNM's mine plan cotttmirrglcs mining solutions with aquifer waters near the Dissolution Stufece. The in-situ pressore of the commingled wares is measured by recording water levels and is controlled to provide pressam grsdiem protection of the overlying USDW aquifers. Aquifer protection compliance is documented with a oominuous in-situ pressws record soil monthly aquifer water quality sampling of the USD W aquifers. Monthly wmer quality sampling of t6o Dissolution Surface Aquifer merely documents the commingling ei~ and does not pmtect err dowment protection of the overiying aquifers. AmetAlia notes that American Soda used the Iowa aquifer about the Dissolution Surface for inaction and diaposai of mining solution. Disposal of injecrod ruining solution both ptessutizea and commingles Dissolution Surface Aquifer waters with mining solutions. AmerAlia does not know if the aquifers e< the American Soda sin are protected by afavorable in-situ pressure gradi®; if the gradient has been maintained, or if in-situ pressures ate oominuously reoartded to determine the impacts of the disposal injection activity. Unlike W RNM end American Soda, AmerAlia has not asked w permit a mine plan whieh included eoanningled rnirtutg solutions with Dissolution Surface Aquifer warms. Instead AmerAlia intends to avoid contaminating the Dissolution Surface Agaifer waters with mining solutions and monroor waver pressures or lords as assurance.
