Working Group on Occurrence and Contaminant Selection Proposed Recommendations
JULY 18, 1997
Background
SDWA 1996 Amendments - by February 1998 EPA shall publish a list
of contaminants, which at the time of publication, are not subject to
any proposed or promulgated national primary drinking water regulations,
which are known or anticipated to occur in public water systems, and which
may require regulation
The list, the Drinking Water Contaminant Candidate List, identifies contaminants
for which the Drinking Water Program will devoted resources toward to
determine the appropriate action regarding the contaminant, whether it
be health advisories, other guidance, toxicity research, and monitoring.
The Candidate List will be used to select contaminants for determining
whether or not regulations will be developed pursuant to the SDWA 1996
Amendments.
The Task - Start with 380 contaminants, use criteria developed
by Working Group on Occurrence & Contaminant Selection, identify contaminants
for a draft Candidate List, approximately 30-50, to be published in order
to seek comment
The Outcome - Based on use of the criteria, 71 contaminants have
been identified for the draft Candidate List
Recommendation
1. It is recommended that the List (see attached) be the draft
Contaminant Candidate List.
2. It is recommended that the List be published as draft in the
Federal Register to seek public comment.
3. It is recommended that in the Federal Register notice
the information needs be specially stated, and comment sought for subsequent
division of contaminants into "categories," dividing contaminants based
on whether there is sufficient or insufficient information for regulatory
determination. It is recommended that additional information and comment
be sought on the inclusion of perchlorate on the final Candidate List.
