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