Hey Dude, glad to hear your getting some rain. Here is a list of drinking water contaminants on the EPA's hit list. Do you think SDIX could whip up a few test kits to help these boys monitor this stuff. Anyone looking for some more really dry reading on the Safe Drinking Water Act can get there fill at epa.gov .
This final CCL will be the primary source of priority contaminants
for the Agency's drinking water program. The list is divided among
priorities for drinking water research, priorities for additional
occurrence data collection, and those contaminants which are priorities
for consideration for Agency determinations of whether or not to
regulate specific contaminants by August 2001.
The SDWA does not preclude the Agency from taking action on a
contaminant not included on the CCL. The EPA can decide to monitor,
develop guidance, or conduct research, for a contaminant not included
on the CCL. The Agency can also develop regulations to address an
urgent threat to public health under SDWA [section 1412(b)(1)(D)]. The
Agency is also not precluded from modifying the CCL prior to the due
date of the next CCL, which is February 2003.
II. Drinking Water Contaminant Candidate List
The following table includes the contaminants, microbiological and
chemical, presented as the Drinking Water Contaminant Candidate List.
The chemical contaminants in the table are identified by name and
Chemical Abstracts Service Registry Number (CASRN). The CCL includes 50
chemical and 10 microbiological contaminants/contaminant groups.

III. Changes Made to Create the Final Contaminant Candidate List Based
on Comments Received on the Draft
The criteria which EPA used to select the contaminants for the CCL
are described in detail in the October 6, 1997 notice (62 FR 52193) on
the draft CCL. In general, the criteria for including a contaminant on
the CCL consisted of determinations of whether the occurrence, or
anticipated occurrence, of a contaminant was likely at levels of
concern to human health. The October notice solicited input from the
public and specifically requested comments on (1) the approach EPA used
to create the list and suggestions on the process for future lists; (2)
contaminants on the list; (3) data needs categories; and (4) whether to
include perchlorate on the CCL. |
