The objective of this study is to develop a methodology for the preliminary screening of surface water quality applicable for use by nondesignated 208 planning agencies. Analytical methods are included for the assessment of rivers, impoundments, and estuaries. Additionally, methods are provided by which point and nonpoint sources can be evaluated. The water quality parameters analyzed for all three water body types are biochemical oxygen demand, dissolved oxygen, temperature, and sediment accumulation. Other constituents, more pertinent to a particular water body type, are also addressed. The analyses are designed to be performed with, at most, the assistance of a desk top calculator and with a minimal amount of data input.
