Water quality

Protecting and restoring water quality is a core mission of the St. Johns River Water Management District. A key component of this work is water quality monitoring and reporting. The agency’s Bureau of Water Resource Information currently operates the districtwide water quality monitoring network, with assistance from the Florida Department of Environmental Protection (DEP). Monitoring provides a wealth of information that enables the district to make resource decisions based on accurate and timely information. In addition, residents can use the information to acquire a basic knowledge of groundwater, springs and water bodies in which they have an interest.

The water quality monitoring network was initially designed and implemented in the early 1980s and has since been improved and expanded. The current network is comprised of approximately 350 long-term sampling stations located on rivers, streams and lakes throughout the district’s 18-county service area. Although a few of the stations are sampled on a monthly basis, most are sampled every other month by trained field scientists. Stations are sampled for a variety of analytes, including nutrients, major ions and physical measurements. Although the majority of the samples are analyzed at the district’s laboratory, some are analyzed at the DEP lab in Tallahassee. Sample result data are stored at the district in a dedicated database, and are also uploaded to the U.S. Environmental Protection Agency’s national Storage and Retrieval (STORET) database.
