Contour mapping is one of the best ways to visualize spatial differences in coastal water quality. The maps presented below are generated automatically on a monthly basis by spatial processes that originally were developed using funding from the Environmental Protection Commission of Hillsborough County (EPCHC), through its Pollution Recovery Fund, with follow-on development funding from Sarasota County. The water quality sampling data that are used to create these maps are collected by the Sarasota County Environmental Services Department.
Change in Water Quality over Time

data starting with the most recent month of data and cycling through to the oldest contour map generated.
Contour maps are generated routinely for the list of parameters shown below. Select from the list below

Monthly Generated Water Quality Contour Maps
Each month new contour maps are automatically generated for the parameters listed below. You can also select a prior year to access archived maps.
The PDF documents below contain maps showing both the parameter distribution within the bays for the selected month, as well as the average monthly distribution for that parameter over the previous ten years (if available).
