Long Term Ground Water Level Monitoring Integrated Hydrologic

• Long Term Ground Water Level Monitoring • Integrated Hydrologic Monitoring • 2003 Annual Conference 19 -Aug-2003 MWMC presentation to NWQMC 1

Long Term GW Level Monitoring Outcome of June 2002 workshop… development of an adhoc workgroup… The purpose of the workgroup is to evaluate existing ground-water level networks in Maryland in order to make recommendations for their enhancement and optimization 19 -Aug-2003 MWMC presentation to NWQMC 2

Long Term GW Level Monitoring Workgroup goals… • Evaluate current ground-wat er level monitoring networks. • Make re commendat ions to improve the network ba sed on monitoring objectives. • Publish a report th at documents the workgroup ’s recommend ations. 19 -Aug-2003 MWMC presentation to NWQMC 3
