Running time is 12 minutes. In the past, hydroseeding large areas was the accepted revegetation method. Today, incorporating regional expertise and scientific research, revegetation is done using native plant species, giving better erosion control, longer plant life spans, and greater drought tolerance. Jump-starting an open area with native vegetation keeps invasives out while attracting larger and more diverse populations of wildlife. In turn, the area becomes a richer, self sustaining habitat with each passing year.
Native plants are the new standard for revegetation of former hazardous waste sites.
Running time is 9 minutes. Seventy years ago the Illinois Basin Oil Fields were abandoned due to declining production and the low price of crude oil. Unfortunately, some of the wells were decommissioned improperly, and now pose a threat to the local groundwater and the environment in general. Region IV and the ERT have stepped in to evaluate the situation and plug the wells. The equipment used to determine the well conditions and the local stratigraphy are detailed and the techniques used to plug the 500-600ft.
