To assist in this effort, please complete and return the User Registration Form on page vii prior to contacting technical support. Technical support for GRITS/STAT is provided through the following services: EPA Office of Research and Development (ORD) Bulletin Board System (BBS) - can be reached at (513) 569-7610. EPA uses the BBS to upload system updates and list changes to both the software and the users manual. You may download these changes free of charge. You may also leave messages concerning questions, comments, or problems on the BBS. EPA GRITS/STAT User Support Hotline - can be reached at (703) 448-6415. Your call will be answered by a voice-mail system. Please leave your name, organization, telephone number, the time of your call, the best time to contact you, and a brief description of the problem. Support personnel will respond to your call during normal business hours (8:30 a.m. to 5:30 p.m. Central Time Monday through Friday). Before calling the GRITS/STAT User Support Hotline, please follow the steps in the Pre-Call Checklist on the next page. If you collect the requested hardware/software information and follow the Pre-Call Checklist, our Software Technicians will be able to help you more quickly and efficiently. Pre-Call Checklist 1. Be sure that you have collected the hardware/software information listed below. 2. Check to see if your computer meets the minimum hardware requirements which are necessary to use this software . Is 570K memory available? Use the DOS command CHKDSK to determine available memory. Are there at least 40 files designated in the CONFIG.SYS file on your system? 3. Check the User Documentation, including this addendum. If your question is not addressed in the documentation, contact the ORD-BBS or the User Support Hotline. Also, before calling the GRITS/STAT User Support Hotline, please consider the following items: 4. If possible, before you call, you should be sitting at your computer, with the computer on and the software loaded. 5. Did the program work correctly at any time previously? If so, have you changed anything vii ------- in the computer environment? 6. Can you reproduce the sequence of steps or the application that demonstrates the problem? Did any error messages appear? If so, exactly what were they? Software/Hardware Information Software version number (i.e., GRITS/STAT 5.0): Processor Type (i.e., 486, Pentium): Available conventional memory: Avaialable EMS/XMS: Operating system name, version (i.e., MS DOS, MS Windows, OS/2): Is software being used on a Local Area Network (LAN)?: TSRs Loaded (i.e., Disk Compression software, Network Drivers, MS DOS Screen Savers, etc.): Video adapter board (i.e., VGA, SVGA): viii ------- FOREWORD The Nationwide GRoundwater Information Tracking System/STATistical Analysis System (GRITS/STAT) is a comprehensive groundwater database system designed to store, analyze, and report data generated during groundwater monitoring programs at RCRA, CERCLA, and other regulated facilities and sites. The current version of GRITS/STAT (5.0) is an integration/upgrade of an existing electronic data base (GRITS 4.2) and the prescribed groundwater statistical procedures. The necessary statistical procedures and the data selection capability are available in the statistical analysis module of the GRITS/STAT system. It is the users responsibility to properly select and statistically analyze the data. Proper data selection and statistical procedures should be obtained from consultation with appropriate EPA staff, reference to the appropriate permit, or reference to the appropriate guidance documents. Proper statistical guidance is provided in the following documents: Statistical Analysis of Ground-Water Monitoring Data At RCRA Facilities - Interim Final Guidance Document, 4/89 (NTIS #PB 89-151-047. EPA/530-SW-89-026) July, 1992 Addendum to the above Guidance Document -Distributed as "Statistical Training Course Materials" available from the RCRA Docket, (EPA/530-R-93-003), Telephone (703) 603-9230. ALSO NOTE THAT THESE GUIDANCE DOCUMENTS IN ADDITION TO THE USER MANUAL CAN BE DOWNLOADED FROM THE INTERNET SITE: http://www.pcengineering.com/~grits As did its predecessor GRITS/STAT 4.2, GRITS/STAT 5.0 provides a flexible user friendly interface for data entry and modification, integrated access to "Industry Standard" IMSL statistical analysis routines, predefined report formats, and data import and export utilities. In addition, GRITS/STAT 5.0 includes many new features that will increase its usefulness as a groundwater data management tool. Most notably, the program has been modified to take advantage of extended memory. While GRITS/STAT 5.0 now requires a minimum of 2 Megabytes of installed Random Access Memory (RAM), many of the memory limitations inherent in earlier versions of the system have been removed. The information stored in the GRITS/STAT system can potentially be transferred to other database/tracking/analysis systems. The modular design of the system lends itself to integration with present and future needs. Prototype modules are implemented in GRITS/STAT 5.0, that export geologic information to the SURFER version 4 modeling package. Requirements are being developed for modules to export mapping information to the ARC-INFO geographic information system (GIS). Soil monitoring data storage is also being investigated as a potential IX ------- enhancement to the GRITS/STAT database system. The development of GRITS/STAT has been a collaborative effort between the U.S. EPA Office of Solid Waste/Permits and State Programs Division, Region 5, Region 7, and the U.S. EPA Office of Research and Development/Center for Environmental Research Information (CERI). The current version of GRITS/STAT reflects numerous years of user groundwater database experience in the regulatory and regulated communities. x ------- xi ------- |
