The National Water Quality Monitoring Council (NWQMC) provides the Water Quality Portal web service to provide users with programmatic access to the large quantities of water quality data in various national databases.
Queries are constructed and submitted through the addition of REST-like parameters to one of two base URL's. Location can be searched by latitude and longitude with radius, coordinate boxing, state, county, and country. Specific site ID's can be used to target an individual station, and searches can be made by other criteria such as site type, organization, and date.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
