Analysis of National Occurrence of the 1998 Contaminant Candidate List Regulatory Determination Priority Contaminants in Public Water Systems

The EPA has determined that there is sufficient info. to support a regulatory determination for a list of 8 Contaminant Candidate List (CCL) chem. contaminants (CT): 3 inorganic CT (manganese, sodium, & sulfate), 3 synthetic organic CT (aldrin, dieldrin, & metribuzin), & 2 volatile organic CT (hexachlorobutadiene & naphthalene). Based on CT occurrence, exposure, & other risk considerations, EPA must determine if regulating the CCL CT will reduce health risks. This report analyzes nat. occurrence data for the 8 CT listed above. Also provides a detailed review of the occurrence data currently avail. to EPA, & used in this analysis, which derived from the required monitoring of the unregulatedÓ contaminants conducted by public drinking water systems.Leonard, Barry is the author of 'Analysis of National Occurrence of the 1998 Contaminant Candidate List Regulatory Determination Priority Contaminants in Public Water Systems', published 2003 under ISBN 9780756735418 and ISBN 0756735416.
