A Pollution Study of
Bayou Texar is one of three urban bayous in Pensacola, Florida being targeted by PERCH (the Partnership for Environmental Research and Community Health) to answer community concerns about environmental health issues. Because the land use around the basin is predominantly residential and commercial, the bayou is subject to urban runoff along its entire length. Over many years, the effect of pollutants on the water quality of the bayou has resulted in fish kills, sewage spills and increased turbidity to the point that the bayou is now only used recreationally for watercraft activities.
Bayou sediments and water samples were collected at strategic locations where data gaps existed from previous county, state and federal studies. Sediments were collected by grabs at the surface and by cores at deeper depths. All samples were analyzed for various pollutants and the results were entered into a Geographical Information System (GIS). From this spatial database an interactive map has been produced. By clicking on individual sample points, the results for that location can be viewed. Click on the toggle icon in the upper left-hand corner of the toolset to see the legend for each layer. The map also includes a bathymetrical layer which was created by surveying the bayou bottom with a GPS mounted to a boat and connected to an echosounder.
