Well Data Sheet Instructions DHS has developed a new version of the Well Data Sheet. This form has long been used in the DHS field offices. The form was reviewed and revised as part of the DWSAP program when it was noted that much of the information needed to do ground water delineations and Physical Barrier Effectiveness(PBE) evaluations is contained in the Well Data Sheet(WDS). DHS staff has typically completed or updated a WDS for each well during the preparation of permit or inspection reports. The fields listed in the new version of the WDS were selected based on input from DHS district offices, as well as some other organizations. No form will contain all the information that is desired by every user. However,-the WDS represents a consensus of the most important information to collect for wells. It was intended that the WDS generally collect objective information about a well. DHS intends to compile the well data sheets into a database,so the form has been programmed in Excel. It is imperative that the fields stay in the order listed,and that entries are made in the appropriate format. Judgment items,such as defects and adequacy.of construction, can be Iisted on a separate sheet. The separate sheet is only for district and LPA use,so it may contain whatever fields are considered appropriate to that office. The WDS is intended to be completed over time,particularly for existing wells. It is not expected that staff will get all the information at one time. Subsequent reviews of the form, such as during field inspections,may yield additional or more accurate information. Completing the WDS is part of normal water system regulatory work. The time it takes to complete the form should be charged to the drinking water regulatory program, not source water assessment. The fields in the form that contain needed information for a DWSAP assessment are noted with an asterisk(*), and DHS staff should make every attempt to collect this information. Whenever a numeric value is requested,enter only the value, not the units. Take note of the units to be used(feet, square feet, gallons per minute,etc.) Sources of Information for Completing the Well Data Sheet For existing sources, start with existing well data sheets in DHS files(if available)_ Additional information for the WDS may be found in DHS or LPA files, such as the well drillers' log and inspection and permit reports. If there is time, DHS staff may review other reports in the water system files. After DHS staff have filled out the WDS with the information readily available,the form may be sent to the water system to review for accuracy and to supplement with additional information.
