The Water Quality Exchange (WQX) is a new framework that makes it easier for States, Tribes, and others to submit and share water quality monitoring data over the Internet.
EPA WQX Has partnered with both federal and state organizations to produce publicly accessible application and services to assist with data submissions.
Water quality research provides the science and tools necessary to develop sustainable solutions to 21st century water resource problems in order to protect human and ecosystem health.
Our nation's waters are monitored by state, federal, and local agencies, universities, dischargers, and volunteers.
Innovative technologies hold the key to cost-effective timely solutions that minimize adverse environmental effects.
