Houston-Galveston Area Council
Environmental Data :: H-GAC
The Houston Galveston Area Council has some of the studies and the results of sampling conducted by several government authorities on their website. The major contamination issues on our bayous is sewage (BOD, coliform, etc.), lawn clippings (BOD, clarity, etc.), and trash. Pesticides, fertilizers are issues but are not as bad. Some Bayous in the lower stretches i.e. Greens Bayou, Patricks Bayou, Sims Bayou have issues with major contaminants from industrial facilities. The San Jacinto River has a major issue with PCBs. In the case of the SJR, the original contamination was thought to come from two old industrial dump sites which have now been cleaned up (look up Sikes Superfund site on EPA webpage), however, agencies were perplexed by continuing bad tests and with the help of some old timers located another dump site at the SJR and I-10 which has long been submerged due to river shift and subsidence. This site is now a declared superfund and has been added to the priority list. Overall though, the bayous (including the ship channel) are in much better shape than they have been in for years we can only hope the progress continues with implementation of TMDLs, better eductaion of the public, and stormwater management plans. In the meantime, I would not recommend eating any fish caught in the bayous or in the San Jacinto River area.
