Sections 504.1, 504.2, 504.3, 509, 519, 523, 523.1, 523.2, 523.3, 524, 525.1 of said Ordinance No. 7583 as adopted in Section
8.04.020 of this chapter are amended to read, respectively, as follows:
Section 504.1 WATER WELL DEFINED. "Water Well" means any drilled,
excavated, jetted, or otherwise constructed excavation which is used
or intended to be used to extract water from or inject water into
the underground for any purpose, or to observe or test underground
waters. This definition shall not include a) salt water wells, b)
wells under the jurisdiction of the State of California, Division
of Oil and Gas, except those wells converted to use as water wells,
or c) wells used for the purpose of 1) dewatering excavation during
construction, or 2) stabilizing hillsides or earth embankments.
Section 504.2 ELECTRODE WELL DEFINED. "Electrode well" means
any artificial excavation in excess of 50 feet deep constructed by
any method for the purpose of installing electrodes or electrical
conductors including, but not limited to, cathodic protection wells
and grounding rod wells.
Section 504.3 ABANDONED WATER WELL DEFINED. "Abandoned water
well" is a nonoperating well which is not maintained in conformity
with Section 519 of this Chapter.
Section 509 PIPE LINE TREATMENT. Every new water main and every
repaired section of an existing water main must be cleared of coliform
bacteria by the proper application of chlorine in sufficient quantities
to give a minimum of 50 parts per million of available chlorine. The
new or repaired pipe shall be thoroughly flushed before and after
chlorination. If the first application of chlorine is not sufficient,
the procedure shall be repeated until the water will meet the standards
set forth in the United States Public Health Service Drinking Water
Standards. Means or methods providing equivalent treatment may be
used if approved by the Health Officer.
Section 519 WELL-SEALING. All water wells and electrode wells
shall be kept sealed and maintained in a manner that will prevent
the entrance of pump leakage, surface drainage, or any other contamination
or pollution into the well or the aquifer, except that nonconforming
wells need not comply with this chapter until such time as the electrode
is expended, or the well is reconstructed, or the well is no longer
being used for its intended purposes, unless, in the judgment of the
Health Officer, such exception constitutes a threat to the quality
of an aquifer.
Section 523 WELLS-DRILLING AND DESTROYING. No person shall drill,
dig, bore, deepen or excavate any well, or destroy an existing well,
without first making application and securing a permit from the Health
Officer.
The application shall be made on a form prepared by the Health
Officer which shall include the location of the proposed or existing
well, the type of casing, the manner of sealings and any other data
required by the Health Officer.
Section 523.1 RECONSTRUCTION OR CONVERSION OF EXISTING WELL
FOR DOMESTIC USE. Any person intending to convert any industrial,
oil or irrigation well for use as a domestic water well, shall first
apply and secure a permit from the Health Officer.
The application shall be made on a form prepared by the Health
Officer which shall include the location of the well, the type of
casing, the manner of sealing and any other data required by the Health
Officer.
Section 523.2 PROCESSING OF APPLICATION FOR WELL DRILLING. Upon
receipt of an application the Health Officer shall make an investigation.
If the applicant has complied with all applicable laws and regulations
and the proposed well location will comply with this Chapter, and
the drilling, digging, boring, deepening, excavating, converting,
destruction or design of the well will not create a condition which
in the opinion of the Health Officer can pollute or contaminate the
underground water, or the water produced by the well, the Health Officer
shall issue the permit.
Section 523.3 VALIDITY OF PERMIT FOR WELL DRILLING. A permit
shall be valid only for the location described on the permit. Construction,
reconstruction or destruction of a well shall be carried out in compliance
with all applicable regulations and requirements of the Health Officer
and with all ordinances and laws of the County of Los Angeles and
of the State of California and shall comply with the terms and conditions
specified in the permit. If any of such conditions, regulations, ordinance
or laws are not complied with, the Health Officer may suspend or revoke
the permit by mailing or personally serving written notice of suspension
or revocation upon the applicant.
Section 524 DESTRUCTION OF WATER WELLS. All water wells, unless
made to comply with Sections 513 and 519 hereof, shall be destroyed
to the satisfaction of the Health Officer by filling with cement grout,
puddled clay or similar impervious material, as approved by the Health
Officer, to thoroughly seal the well including all voids, annular
spaces, gravel envelopes or other spaces, as necessary to protect
the aquifer.
Section 525.1 DISINFECTION AND BACTERIOLOGICAL QUALITY OF DOMESTIC
WATER WELLS. Every new, repaired or reconstructed domestic water well,
after completion of construction, repair or reconstruction, and before
being placed in service, shall be thoroughly cleaned of all foreign
substances. The well, including the gravel used in gravel-packed wells,
the pump, and all portions of equipment coming in contact with well
water shall be disinfected with a solution containing at least 50
parts per million available chlorine, which shall remain in the well
for a period of at least 24 hours, or by an equivalent method of disinfection
satisfactory to the Health Officer, and such procedure shall be repeated,
as necessary, to produce water meeting bacteriological standards as
set forth in the United States Public Health Service Drinking Water
Standards. No well water from a new or reconstructed well shall be
used for domestic purposes until the water meets such bacteriological
requirements.
