As part of the Water Campus Advanced Water Treatment (AWT) Facility expansion, the City of Scottsdale (COS), Arizona, evaluated expanding their
compounds of potential concern (CPC) monitoring program to determine whether an additional
treatment process will help them meet their water quality goals.
The objective of this study was to identify the CPCs that could be
monitored and potentially reduced through Scottsdale's current
treatment processes and any potential future treatment processes.
The list development process consisted of several prioritization
steps to reduce the number of targeted CPCs to a manageable
number for routine monitoring. The first step in the CPC evaluation was to develop a broad list of CPCs that could
be present at the COS AWT. This initial CPC List included compounds already
monitored by COS, compounds for which COS has internal laboratory standards,
compounds frequently cited in current literature (with emphasis on research
associated with wastewater and reclaimed water systems), compounds
representing different categories (e.g., pharmaceuticals, industrial compounds,
steroids), compounds monitored by wastewater utilities whose operations are
similar to those at the COS, and compounds listed on selected regulatory watch
lists. The paper provides a brief description of the information sources
and selection criteria used in developing the Initial CPC List. Includes 5 references, tables, figure, appendix.
