It goes on to state that there appears to be no effect from pumping the municipal wells on the <br />water level in the surficial material. It further recommends that long-term monitoring of the surficial <br />aquifer be conducted. The Council concurs with this recommendation. Two years of data is not <br />sufficient to show the long-term effects of pumping. The fact that the water level in the two wells <br />analyzed level off after a short period of pumping may indicate that water is leaking from the surficial <br />aquifer. <br /> <br />In addition, the tritium sampling discussed on pages 19-2 and 19-3 of the EAW indicate that water in the <br />City's municipal wells has recharged within the last 50 years suggesting a connection between the <br />surficial and bedrock aquifers. The Council is currently undertaking studies to evaluate the ability of the <br />FIG aquifer to support planned growth in the northwest metropolitan area. While the study conducted for. <br />the AUAR concludes that the FIG has sufficient capacity to support growth, the Council recommends that <br />the city continue monitoring water levels to establish long-term trends and further evaluate aquifer <br />capacity and potential impact on surface water features. <br /> <br />This concludes the Council's review of the AUAR. The Council will take no formal action on the <br />AUAR. Council staff recommends that the city evaluate the comments contained herein before <br />distribution of the final AUAR and mitigation plan documents.
