Full Description

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