<br />California Health & Safety Code
<br />§115700 (a) Every person owning land in fee simple or in possession thereof under lease or contract of sale who knowingly permits the existence on the premises of any abandoned mining shaft, pit, well, septic tank, cesspool, or other abandoned
<br />excavation dangerous to persons legally on the premises, or to minors under the age of 12 years, who fails to cover, fill, or fence securely that dangerous abandoned excavation and keep it so protected, is guilty of a misdemeanor. (b) Every person
<br />owning land in fee simple or in possession thereof under lease or contract of sale who knowingly permits the existence on the premises of any permanently inactive well, cathodic protection well, or monitoring well that constitutes a known or
<br />probable preferential pathway for the movement of pollutants, contaminants, or poor quality water, from above ground to below ground, or vertical movement of pollutants, contaminants, or poor quality water below ground, and that movement poses
<br />a threat to the quality of the waters of the state, shall be guilty of a misdemeanor. (c) For purposes of this section, 'well includes any of the following: (1) A °monitoring well" as defined by Section 13712 of the Water Code. (2) A "cathodic well" as
<br />defined by Section 13711 of the Water Code. (3) A 'water well" as defined by Section 13710 of the Water Code. (d) A "permanently inactive well" is a well that has not been used turn period of one year, unless the person owning land in fee simple
<br />or in possession thereof under lease or contract of sale demonstrates an intent for future use for water supply, groundwater recharge, drainage, or groundwater level control, heating or cooling, cathodic protection, groundwater monitoring, or related
<br />uses. A well owner shall provide evidence to the local health officer of an intent for future use of an inactive well by maintaining the well in a way that the following requirements are met: (1) The well shall not allow impairment of the quality of water
<br />within the well and groundwater encountered by the well. (2) The top of the well or well casing shall be provided with a cover, that is secured by a lock or by other means to prevent its removal without the use of equipment or tools, to prevent
<br />unauthorized access, to prevent a safety hazard to humans and animals, and to prevent illegal disposal of wastes in the well. The cover shall be watertight where the top of the well casing or other surface openings to the well are below ground
<br />level, as in a vault or below known levels of flooding. The cover shall be watertight if the well is inactive for more than five consecutive years. A pump motor, angle drive, or other surface feature of a well, when in compliance with the above
<br />provisions, shall suffice as a cover. (3) The well shall be marked so as to be easily visible and located, and labeled so as to be easily identified as a well. (4) The area surrounding the well shall be kept clear of brush, debris, and waste materials.
<br />(e) Ala minimum, permanently inactive wells shall be destroyed in accordance with standards developed by the Department of Water Resources pursuant to Section 13800 of the Water Code and adopted by the State Water Resources Control
<br />Board or local agencies in accordance with Section 13801 of the Water Code. Minimum standards recommended by the department and adopted by the state board or local agencies for the abandonment or destruction of groundwater monitoring
<br />wells or class 1 hazardous injection wells shall not be construed to limit, abridge, or supersede the powers or duties of the department, in accordance with Section 13801 of the Water Code.
<br />§115710 The board of supervisors shall order securely fenced, filled, or covered any abandoned mining shaft, pit, or other excavation on unoccupied land in the county whenever it appears to them, by proof submitted, that the excavation is
<br />dangerous or unsafe to man or beast The cost of covering, filling, or fencing is a county charge.

<br />Destruction of Wells. §6.1.When swell no longer functions as originally designed, or cannot appropriately function in place of another design, or has fallen in to such a state of disuse or disrepair that it may become a source of impairment to the
<br />ground water quality, constitutes a safety hazard, or found to be abandoned, it must be destroyed under a well destruction permit § 6.2. All oil residue from oil tubed pumps shall be removed and disposed of property. § 6.3. Sealing Requirement. §
<br />6.3.1. When a well is to be destroyed, the interior of the casing shall first be cleared to eliminate any obstructions, which might interfere with effective sealing procedures. § 6.3.2. The open well may then be filled with approved filler material from the
<br />bottom up to 100 feet below the ground surface; however a deeper seal may be required by the Director according to site specific requirements. The approved sealing material (see Section 4.7.3.) shall be installed from the filler material to the top
<br />of the casing. § 6.3.3.1f there is no annular seal or the integrity of the seal or the well is unknown, or the well is gravel packed, the casing shall be perforated upward beginning just above the filler material to the surface. Grout shall be applied
<br />above the approved filler material in such a manner that the grout will be forced out of the perforated holes, forming a barrier to the vertical movement of water. § 6.3.4. Where the maximum depth of a well being destroyed is less than 100 feet, and
<br />there is no standing water, the well shall be sealed from the bottom to its total depth with grout, Bentonite, or a minimum of five (5) sack mix of concrete not greater than %" aggregate, or as specified by the Director. § 6.3.5. Approved Bentonite may
<br />be allowed to freefall up to 200 feet in a well destruction if the space will allow no bridging, and if done in accordance with manufacturer's specification. § 6.3.6. For the protection of the seal, and to facilitate the future use of the land site, a hole at
<br />least one foot larger in diameter than the originally drilled hole shall be excavated around the outside of the well casing to a depth not less than three feet below the ground surface. The well casing shall then be cut off six inches above the bottom
<br />of this excavation and removed. During the sealing operation, the grout used to fill the well shall be allowed to spill over into the excavation and fill it for a thickness of one foot and form a cap which has a diameter of at least on foot greater than the
<br />diameter of the originally drilled hole. This procedure should result in the exposed edge of the casing being covered with six inches of grout After the sealing operation and the sealing material have set, the excavation shall be back filled with clean
<br />native soil.
<br />§ 6.3.7. Under no circumstances shall an abandoned well be used for disposal of any solid or liquid wastes. § 6.3.8. If a test hole is drilled for construction of a well, and is not used in the final construction of the well, the test hole shall be destroyed
<br />from the total depth to the surface and under inspection.
