Eastern San Joaquin Groundwater Basin Groundwater Management Plan <br />Northeastern San Joaquin County Section 5 <br />Groundwater Banking Authority 91 Groundwater Monitoring Program <br />2. Develop the tools necessary to analyze groundwater data. <br /> <br />GIS applications used to perform groundwater analysis are increasingly powerful. ESRI, <br />the leader in GIS technology, has developed proven GIS tools that are capable of <br />performing the following: <br /> <br />• Groundwater level and water quality contouring <br />• 3-D visualization of groundwater characteristics <br />• Geospatial report generation <br />• Relational data analysis <br /> <br />3. Make groundwater information available to decision makers, agency staff, and the general <br />public through the internet. <br /> <br />GIS is now available via the internet. Users will be able to access the database through <br />the internet and will be able to query selected well data and view graphical <br />representations of groundwater conditions. This eliminates the need for users to be <br />trained in GIS and also the associated software license costs. The following is a list of <br />on-line features: <br />• Downloadable historic semi-annual groundwater reports <br />• Graphical user interface (GUI) <br />• County base map with crop information, well locations, agency boundaries, <br />recharge areas, well fields, water level contours, etc. <br />• Data query and download into MS Excel or HTML <br /> <br />4. Create an efficient and enforceable QA/QC plan: <br /> <br />To effectively manage groundwater, decision makers need to know what is physically <br />going on in the sub-surface. Over the next 20-30 years, San Joaquin County will invest <br />hundreds of millions of dollars for projects in restoring and protecting the underlying <br />groundwater basin. Therefore, confidence in the integrity and accuracy of groundwater <br />data is of utmost importance. Also, State law mandates that agencies adopt <br />groundwater monitoring protocols for quality assurance and quality control (QA/QC). By <br />eliminating manual data entry through electronic data logging and utilizing advances in <br />portable Global Positioning Systems, we can reduce human errors, create a monitoring <br />system with quality assurance tests, and minimize labor costs associated with data entry <br />and database correction. The new QA/QC plan will include: <br /> <br />• Electronic data logging using Palm Pilots <br />• Electronic data upload to database <br />• Remote database entry forms <br />• Location checks using hand-held GPS units <br />• Telemetry and remote data logging <br />• Monitoring protocols <br />• Sampling techniques <br />• Acceptable laboratory methods <br />• Health and safety <br />• Database security <br /> <br />
