About the presentations:

LT2ESWTR Rule

ADEQ will be providing training to public water systems and certified
operators on the new Long Term 2 Enhanced Surface Water Treatment Rule
(LT2ESWTR).  Professional development hours will be awarded.

The LT2ESWTR applies to all public water systems (systems) that use
surface water or ground water under the direct influence of surface
water.  
The purpose of the LT2 rule is to reduce illness linked with the
contaminant Cryptosporidium and other disease-causing microorganisms in
drinking water. The rule will supplement existing regulations by
targeting additional Cryptosporidium treatment requirements to higher
risk systems. This rule also contains provisions to reduce risks from
uncovered finished water reservoirs and to ensure that systems maintain
microbial protection when they take steps to decrease the formation of
disinfection byproducts that result from chemical water treatment.

LT2 will improve the control of Cryptosporidium and other
microbiological pathogens in drinking water systems with the highest
risk levels. EPA estimates that full compliance with the LT2 will reduce
the incidence of cryptosporidiosis - the gastrointestinal illness caused
by ingestion of Cryptosporidium. The additional Cryptosporidium
treatment requirements of the LT2 will also reduce exposure to other
microbial pathogens, such as Giardia, that co-occur with
Cryptosporidium. Additional protection from microbial pathogens will
come from provisions in this rule for reviewing disinfection practices
and for covering or treating uncovered finished water reservoirs, though
EPA has not quantified these benefits.
_________________________________________________________Stage 2 DBP
Rule

ADEQ will be providing training to public water systems and certified
operators on the new Stage 2 Disinfectants and Disinfection Byproducts
Rule (Stage 2 DBP rule).   Professional development hours will be
awarded.

The Stage 2 DBP rule applies to community and nontransient, noncommunity
water systems that add and/or deliver water that is treated with a
primary or residual disinfectant other than ultraviolet light.  The
Stage 2 DBP rule builds upon earlier rules that addressed disinfection
byproducts to improve your drinking water quality and provide additional
public health protection from disinfection byproducts. This final rule
strengthens public health protection for customers by tightening
compliance monitoring requirements for two groups of DBPs,
trihalomethanes (TTHM) and haloacetic acids (HAA5). The rule targets
systems with the greatest risk and will reduce potential health risks
related to DBP exposure and provide more equitable public health
protection.
