Once you get into the main mapping screen, choose the 'special projects' button and choose the 'water quality sampling stations' button. It takes some time to load, but the dots are on the map. You will have to use the "InfoTips" feature tab on the left side to find out which dot is what site, but you can zoom in and out to whatever scale you want.

USGS Water Quality Data

Water-quality data from the National Water Information System (NWIS) of the U.S. Geological Survey (USGS) can be readily accessed online in a comparable format to data housed in the Storage and Retrieval (STORET) water-quality system of U.S. Environmental Protection Agency’s (USEPA).To access the USGS water-quality web service, please go to http://qwwebservices.usgs.gov

The USGS water-quality web service provides data from the NWISweb database (http://waterdata.usgs.gov/nwis), which hosts 4.3 million samples and 72 million results representing approximately 368,000 sites across the United States from over a century of monitoring.

http://water.usgs.gov is the USGS home page for Water Resources of the United States

US EPA Data

The USEPA water-quality web service provides data from the STORET data warehouse that contains biological, chemical, and physical data on surface and ground water collected by federal, state and local agencies, Indian Tribes, volunteer groups, academics, and others (http://www.epa.gov/storet/web_services.html). All 50 States, territories, and jurisdictions of the U.S. are represented.
