USGS NAWQA Surface Water Monitoring Program

Page history last edited by lesman@... 9 years, 7 months ago

The National Water-Quality Assessment Program (NAWQA) provides an understanding of water quality conditions; whether conditions are getting better or worse over time; and how natural features and human activities affect those conditions.  Regional and national assessments are possible because of consistent study design and uniform methods of data collection and analysis.  The parameters sampled and their corresponding methods for field sampling and laboratory analysis are linked to published documents below.
