Dissolved Oxygen Criteria in Surface Waters

Under the most recent Triennial Review of surface water quality standards, the State of Florida has revised its surface water criteria for dissolved oxygen (DO). The revised DO criteria are expressed as percent saturation DO instead of the older concentration-based criteria.  These revised criteria are designed to recognize the inherent natural variability in DO levels and protect the designated use of Florida’s surface waters.  The revised criteria are for both fresh and marine waters.  Endangered sturgeon in the Suwannee, Withlacoochee, and Waccasassa Rivers receive additional protection from higher percent saturation DO criteria.  The revised criteria also include a trend test to further provide water quality protection.  The revised DO criteria are included in the new Rule 62-302.533, Florida Administrative Code.
