Contamination
The Seymour Aquifer is depended on widely for irrigational, municipal, domestic, and livestock water purposes . The prevention and protection of this aquifer are very important to the consumers. The aquifer is very susceptible to pollution from both near surface and surface sources. Some factors that enable pollution of the aquifer are infiltration potential, thickness, geologic character, rate of groundwater movement, and depth of the water table. The sandy characteristics of the soils increase the infiltration potential and also the aquifer is not protected by an overlying impermeable bedrock structure. These factors increase the accessibility, water movement, and overall protection of the aquifer. The Seymour is quite thin in depth and water table thickness, this is also another characteristic that causes problems. The pollutants from surface and near surface can travel quickly and spread reasonably quickly due to the coarse-grained make-up of the formations. This causes the natural-groundwater movement to exceed in speed (Harden, 1976).
The contamination of the aquifer is mainly from pesticides and fertilizers used in agriculture practices. This isn’t located in one certain area, but mostly throughout the extent of the aquifer. Another factor is from human and animal wastes like leaky septic tanks, feedlot waste, and sewage-treatment plants. A localized problem in certain areas of the aquifer, is brine disposal and well leakage from oilfield practices. (Ryder, 1996)
