  § 6-7.05. Log of well.  

Latest version.

  • (a)

    Licensed water well contractors who have performed any work for which a permit is required by this chapter and which work involves drilling, digging, excavating, or boring of a well, except for an engineering test hole, shall, within thirty (30) days of completion of such work, submit to the Department/Agency an accurate and complete well completion report.

    (b)

    For the purpose of obtaining sealing requirements from the Department/Agency, geophysical well logs will be required as described in this chapter. New water wells in Sealing Zone III of the County's Sealing Zone Map shall have a geophysical log. New water wells in Sealing Zone II of the County's Sealing Zone Map shall either have a geophysical log or soil samples shall be collected and recorded for every ten feet of depth within potential sealing zones. Geophysical logs must include spontaneous potential, and resistivity (short and normal, or lateral log). All abandoned water wells to be destroyed in Sealing Zones II and III shall have a geophysical log by gamma-ray if no existing electric log or satisfactory drilling report is available for that well, unless it is determined by the Department/Agency that a log is not warranted.

    (c)

    Any permittee whose water well contractor fails to comply with this provision shall be in violation of this chapter and shall not be granted any new permits until the violation has been corrected. This shall not preclude the application of other penalties for violation of this chapter. A well log shall include, at a minimum, all of the following:

    (1)

    A detailed record of the boundaries, character, size, distribution, and color of all lithologic units penetrated.

    (2)

    The type and size of well casing.

    (3)

    The location of perforations, sealing zones and existing seals.

    (4)

    Reports on the quantity and quality of groundwater.

    (5)

    Any other data required by the Department/Agency as a condition of the permit.

    (d)

    Pursuant to Water Code Section 13752, well completion reports are confidential and not available to the public, but may be available to governmental agencies for use in making studies, or to any person who obtains a written authorization from the owner of the well. The Department/Agency is not authorized to release well completion reports without written authorization from the California Department of Water Resources.
