Detection and Measurement of Pollution and Its Effects on Marine Organisms in Chiltipin Creek and Copano Bay - Pollution Abatement in Region V
Chiltipin Creek, previously classed as a route for disposal of industrial wastes, has no commercial or recreational value from a fisheries viewpoint. However, it empties into a body of water that is valuable to both the commercial and sports fishery. The creek carried a load of oil which can produce profound changes in a marine environment. Water soluble extracts from the oily waste exert a direct toxic action upon some lower invertebrates, causing an upset in the natural food cycle. This extract inhibits feeding activities of oysters, resulting in death as well as causing an oily taste, and tends to force game fish and shrimp from the area. Settled oil covers bay bottoms, destroying fertile areas necessary for nursery grounds. With the continuation of oily wastes carried by Chiltipin Creek, the Copano Bay area would be virtually destroyed. However, through cooperation from the Railroad Commission in issuing pipeline and production severances to those companies in violation, the conditions of Chiltipin Creek have improved considerably over the previous year.
