The proposed approach for determining the <br /> infiltration rate and TDS loading into ground water, appears reasonable. <br /> 4 <br /> We request the following changes and additions: <br /> r <br /> 1 . The evaporation pan and corresponding weather measuring devices should be placed at <br /> the holding ponds, if feasible. <br /> 2 . Ground water (GW) elevation contours and concentration plots must be developed from <br /> the data measurements made from the five City of Tracy monitoring wells. <br /> 3 . Compare available GW elevation data from adjacent facilities, i.e. , Leprino pretreatment <br /> ponds, Holly Sugar, etc. ; and regional ground water elevation data. <br /> 4 . Add bicarbonate concentration measurements to analyses to be performed on monitoring <br /> wells . <br /> If you require any additional information please call me at (916) 255-3030. <br /> n <br /> � j;l ( 'w ti <br /> 11 - 1' <br /> MICHAEL H.
