Utilizing Online Maps for Water Quality Data: A Comprehensive Overview

This presentation highlights the use of online platforms for accessing and visualizing water quality information collected by the USGS NAWQA. It covers essential features like data summaries, retrieval methods, and mapping options. The system includes over 14 million data values from thousands of surface water sites and wells, nutrient and contaminant samples, and biological community data. Attendees will learn how to effectively use the website for research, explore GIS mapping capabilities, and compare results against national and regional backgrounds.
