State
Board Punts on Pathogens in Water
A. Antibiotic Resistance
and Pathogens
Comment A.1:
The proposed Policy should address the potential impact
to public health from antibiotic resistant pathogens
and antibiotic resistant genes in recycled water. The
disinfection procedures specified in the Title 22 regulations
do not provide adequate protection against this threat.
(18.6, 18.7, 71.9, 81.2, 81.6, 81.12, 1802.2, 1802.3,
1803.1, 1803.3, 1804.4, 1804.6, 1804.7, 1804.8)
Response:
Establishing criteria, including criteria for pathogens
and antibiotic resistant genes, for recycled water
to protect public health is a responsibility of the
California Department of Public Health (CDPH). This
is specified in Water Code section 13521. The Water
Code requires water reclamation requirements issued
by the Regional Water Boards to be in conformance with
the uniform criteria established by CDPH.
CDPH has not established criteria for groundwater recharge
reuse. It provides recommendations to the Regional
Water Boards on a case-by-case basis on what requirements
should be established to protect public health. The
proposed Policy requires Regional Water Board to implement
the CDPH recommendation, unless conflict resolution
procedures are in 1996 Memorandum of Agreement (MOA)
between the State Water Board and CDPH are exhausted.
Again, it is CDPH’s responsibility to evaluate
the commenters’ concern and make appropriate
recommendations.
CDPH reports that antibiotic resistant genes have been
found in drinking water and recycled wastewater, that
their impact on public health is unknown, and that
this potential impact may warrant further study. It
is considering taking actions to evaluate whether antibiotic
resistant genes in recycled water present a risk to
public health.
Comment A.2:
Sewage sludge contains pathogens, pharmaceuticals,
and endocrine disrupters. The pyrolysis method (an
anaerobic heating process to decompose organic materials)
should be used to treat sewage sludge. This method
reduces methane production; destroys pathogens and
pharmaceuticals; and converts sludge into energy. (81.3,
1804.5)
Response:
This is not a comment on the proposed Policy. The proposed
Policy concerns the use of recycled water, not the
land application or disposal of sewage sludge or biosolids.

Did you know that Sonoma
county's treatment plants are only capable of removing
about 75 chemicals out of 87,000 known contaminants?
FULL treatment however, removes EVERYTHING. Watch Fred
Corson, Ph.D. explain in this video presentation!
