Over the last two decades concerns over water contamination in the Galveston Bay and Houston Ship Chanel has increased with manufacturing byproducts such as polychlorinated biphenyls (PCB) show up in increasing concentrations.

PCBs are manufactured organic chemicals that do not posses a smell or taste and are noted as not only possible carcinogens but have been shown to cause birth defects in babies born to women who ingest them. For the Ship Channel and Galveston Bay the presence of PCBs have led to an ever growing list of native fish from the waters that cannot be eaten due to the contamination yet fishing along these areas is still a common practice.

As recently as March of 2016 new and large leaks have been discovered along the waterways raising new concerns over the extent of the contamination.

Using data gathered by the Texas Commission on Environmental Quality over the last decade as well as public health records we hope to chart out the definitive impact of PCB and dioxin contamination in the Houston Ship Channel and Galveston Bay Area.
