The National Surface Water Survey (NSWS) of the National Acid Precipitation Assessment Program (NAPAP) is a three-phase project to evaluate the current water chemistry of lakes and streams, determine the status of fisheries and other biotic resources, and select regionally representative surface waters for a long-term monitoring program. The manual provides details of the analytical methods and internal quality control used to process and analyze samples for Phase I of the National Stream Survey. Analytical protocols are given for 24 chemical parameters commonly of interest in surface water studies and considered to be applicable to acid deposition investigations. The methods are generally adapted from, 'Methods for Chemical Analysis of Water and Wastes', EPA 600/4-79-020 and, 'Standard Methods for the Examination of Water and Wastewater', the American Public Health Association. They are essentially the same methods as those used for the Eastern Lakes Survey (EPA 600/4-86/009) except that an automated (flow injection) colorimetric method for nonexchangeable 'monomeric' aluminum using pyrocatechal violet is added. A choice of methods (flame AAS, ICP) is given for several of the cations under the condition that the required instrumental detection limits are achieved.
