Cal. Code Regs. Tit. 22, § 64212 - Bacteriological Quality Monitoring
(a) A water supplier operating a state small
water system shall collect a minimum of one routine sample from the
distribution system at least once every three months. The sample shall be
analyzed for the presence of total coliform bacteria by a laboratory certified
by the State Board for bacteriological analyses pursuant to Article 3,
commencing with section
100825, of Chapter 4 of Part 1 of
Division 101, Health and Safety Code. The results of the analyses shall be
reported to the local health officer no later than the 10th day of the month
following receipt of the results by the state small water system.
(b) If any routine sample is total
coliform-positive, the water supplier shall collect a repeat sample from the
same location within 48 hours of being notified of the positive result. If the
repeat sample is also total coliform-positive, the sample shall also be
analyzed for the presence of fecal coliforms or Escherichia
coli (E. coli). The water supplier shall notify the
local health officer within 48 hours from the time the results are received and
shall take corrective actions as directed by the local health officer to
eliminate the cause of the positive samples.
(c) A local health office may require a state
small water system to sample the distribution system each month, in lieu of the
requirements of subsection (a), if the system has bacteriological contamination
problems indicated by more than one total-coliform positive sample during the
most recent 24 months of operation. The monthly sample shall be analyzed for
the presence of total coliform bacteria by a laboratory certified by the State
Board for bacteriological analyses pursuant to Article 3, commencing with
section 100825, of Chapter 4 of Part 1 of
Division 101, Health and Safety Code. The results of the analyses shall be
reported to the local health officer no later than the 10th day of the month
following receipt of the results by the state small water system.
