FORMS - Well schedule revision UNITED STATES DEPARTMENT OF THE INTERIOR GEOLOGICAL SURVEY Water Resources Division Washington 25, D.C. In reply refer to: March 6, 1958 Code 4052 0001 GROUND WATER BRANCH MEMORANDUM NO. 58.33 To: District Chiefs and Staff Officials, Ground Water Branch From: Chief, Ground Water Branch, Washington, D.C. Subject: FORMS - Well schedule revision During the past several years there has been considerable discussion regarding the desirability of revising the Well Schedule Form (9-185), and two memoranda have been sent to the Field offices asking for opinions on the subject. The replies from the Field offices have been studied carefully, and a revised experimental well schedule prepared that incorporates as many as possible of the suggested revisions. It is recognized that this schedule will not meet the needs of all the Field offices, and that some of the offices may need to continue using specially designed forms, or supplemental forms that meet special requirements in particular areas. Some special requirements may be met by modifying the well schedule by rubber stamping on the reverse side. The Field office voted overwhelmingly in favor of retaining the present 5 X 8 inch form with the back side blank. With these restrictions, it was possible to make only a few of the many changes and additions requested by the Field offices. The recommended changes and additions were tabulated and the ones most frequently recommended were made. Space for the additional requested items was made by better utilizing the space at the top of the schedule and by reducing the space allowed for some of the items. Spaces for the well number have been incorporated at both the top and bottom of the sheet. The well number space at the bottom was provided to make it easier to index the schedules when a bunch of schedules are kept on a clip board or in a book. The well number space at the bottom was placed on the lower right-hand side to make it easier to index the schedules when filed in a standard 5 X 8 inch file. Item 6 was arranged to provide space for casing diameters where more than one size of casing is used in a well. Item 8 was enlarged to allow space for both reported and measured depths. Frequently the reported depth to water at some previous date is significant. Item 9 was designed to provide space for additional data on pump performance. Item 12 provides space for recording chemical quality date, but eliminates some of the wasted space that had been used to record data only infrequently. The space thus saved was added to the space for "Remarks" which can be used to record additional chemical quality data if needed, but also may be used to record other miscellaneous data. Enclosed are copies of the revised experimental well schedule. Each Field office is requested to study the schedule carefully and fill out the attached form and return it to this office by April 15, 1958. A few of the Field offices have expressed an interest in the use of Keysort system for recording well data. This system has its advantages and disadvantages and because of the large amount of time and effort that would be required to change to and maintain this system, it is felt that the subject should be thoroughly studied. In order to help this office determine whether there is sufficient interest in and need for this system to justify a study, please answer the questions regarding the Keysort system. (s) A. N.
