Specifications include, but are not limited to: The Division implements a statewide surface water-quality monitoring program to provide data and information to support water-quality management decisions. Chemical data collected from rivers, lakes and streams are used to determine ambient water quality conditions and trends, establish water quality standards (WQS), evaluate if WQS are being met and develop pollution control plans such as total maximum daily loads. All water samples are collected according to standard operating procedures described in the Nevada Quality Assurance Program Plan for Surface Water Sampling approved by the U.S. Environmental Protection Agency. All samples delivered for laboratory analyses are accompanied by chain-of-custody documentation. Water samples are analyzed for routine parameters, bacteria and metals as specified by the Division for each sample, according to approved analytical methods and for the cost as indicated in the Cost Schedule. This scope of work is for two (2) years of laboratory services to be provided by the selected analytical laboratory.
