(FOA)-Analysis
of Corrosion Control Treatment for Lead and Copper Control; September 12, 2019
Agency
The
Water Research Foundation (WRF)
Description
This
RFP aims to evaluate analysis tools for, and risks from, implementing and/or
changing corrosion control treatment (CCT), and to explore the potential impact
of various source water or treatment changes to CCT. To develop a framework for
how to assess current CCT and under what circumstances CCT should be
re-evaluated. Impacts to both lead and copper should be explored. There is
renewed interest from regulatory agencies and utilities in evaluating current
CCT practices. Proposed revisions to the Lead and Copper Rule are expected in
the near future. Potential CCT options that are being considered for the
updated LCR include (EPA 2016a):
•
Requiring large water systems (serving >50,000 people) to evaluate and
re-optimize CCT when EPA publishes updated CCT guidance
•
Requiring all systems in the U.S. to implement CCT, regardless of system size,
tap sampling results, or the presence of lead service
lines
Many
questions arise when water systems are faced with evaluating their CCT: • How
can CCT be evaluated, and how does one choose what method to use?
•
What triggers a need to re-evaluate CCT?
•
How are the CCT study results interpreted – is one treatment demonstrably better
given variability in data?
•
What are the unintended consequences to consider?
•
If a change is to be made, how is the transition and evaluation of the success
of the new CCT strategy made? In the future, water utilities will continue to
need resources to help them navigate uncertainty related to CCT. This project
will provide utilities with information to help them better understand when to
reevaluate CCT, appropriate methods to assess/re-evaluate CCT, and potential
risks from making changes to CCT.
The
final resources for this project are expected to be useful to utilities with
various levels of financial resources and expertise. The approach should
reflect a recognition of this issue, and the final project resources should
provide information that is actionable by all utilities.
