Development and application of a multimedia model to assess fate and transport of organic chemicals in a South Texas lake

The coastal bend region of South Texas has undergone significant changes in recent times. Increased agricultural activities, industrialization and population growth have enhanced the releases of organic chemicals in South Texas environments. Several classes of organic contaminants have been detected in air, water and sediment samples collected in this region. There is a growing concern that this increased usage may lead to unacceptable exposures and pollute surface-water bodies used for water supply purposes.
