i Water Well Report SUMMARY Water Well Report TM Research Mapping Protocol Fidelity National Information Solutions Water Well Reporim is prepared from existing state water well databases and additional Tile datalrecords research conducted at Texas regulatory authorities Submission of drillers log records upon completion of a drilled water well became mandatory in 1985 Ths-state of Texas has processed these records into several different filing systems within two state regulatory authorities The water well files,records and map locations are maintained by the Texas Natural Resource Conservation Commission(TNRCC)and the Texas Water Development Board(TWDB) Actual water well site locations of this report are geocoded and geoplotted directly from the drilling records,drilling schedules,and driller's logs and maps submitted by the water well driller and maintained at these two primary water well regulatory authorities Below is a description of th,e four filing systems utilized for well drilling records Texas Water Development Board (TWDB) Texas Water Development Board maintains a file system of located water well locations These well files are water well site locations that have been verified with a field inventory inspection by TWDB personnel The wells are assigned a State Identification Number unique to that well and plotted on county base maps U S G S 7 5 minute topographical quadrangle maps and in-house geographic information system Records will also include analytical data attached with each drilling record This is the current protocol for maintaining water well records within the TWDB Texas Natural Resource Conservation Commission (TNRCC) The Texas Natural Resource Conservation Commission maintains a file system of plotted,partially numbered,and un numbered water well locations Plotted water well files are water well slte locations that have been determined from map information submitted on water well logs and subsequently plotted on TWDS county highway base maps This type of mapping and filing procedure ceased in June 1986 Partially numbered waterwell files are water well site locations processed from 1986 through 1990 These wells are provided a State Identification Number which establishes the well location somewhere within a 2 5 minute quadrant of a 7 5 minute quadrangle map but the site location has never been precisely mapped or verified by a State of Texas staff member Un numbered water well files are water well site locations that have been processed since June 1990 These well records are filed solely on their county location and are not provided a State Ident+fiation Number nor are they mapped This is the current protocol for maintaining water well records within the TNRCC Disclaimer Fidelity National Information Solutions has performed a thorough and diligent search of all wells recorded with the Texas Water Development Board and the Texas Natural Resource Conservation Commission All mapped locations are based on information obtained from the TWDS and the TNRCC Although FNIS performs quality assurance and quality control on all research projects,we recognize that any inaccuracies of the records and mapped well locations could possibly be traced to the appropriate regulatory authority or the water well driller Many water well schedules may have never been submitted to the regulatory authority by the water well driller and thus may explain the possible unaccountability of private drilled wells It is uncertain if the above listing provides 100%of the existing well locations within the area of review Therefore,Fidelity National Information Solutions cannot gaurantee the accuracy of the data or well location(s)of those maps and records maintained by Texas'regulatory authorities 0
