Water Quality Sampling


Water chemistry samples are routinely collected by the Central District's Watershed Monitoring (WMM) staff. One of five basins within the Central District is sampled annually on a rotating basis. Every five years each basin is revisited and undergoes a more targeted sampling routine.  Each impaired water body within a basin is sampled at least one time every quarter, depending on the size of the water body.

All sample collection procedures and associated field activities are performed in accordance to DEP's Standard Operating Procedures. With the exception of fecal coliform samples, all samples are shipped to DEP Central Laboratory in Tallahassee on a daily basis to meet holding times. Fecal coliform samples, which must be analyzed within eight hours of the collection time, are delivered to a local contract laboratory for analysis.
