Acid Mine Drainage Remediation

Icon: 
Streaming icon

In this video, an environmental technologist visits an abandoned coal mine in Kentucky to talk about how a remediation system (a series of settling ponds and treatment cells) is neutralizing the acid drainage from the mine and preventing damage to a creek downstream. He shows the path of the acid drainage as it flows down a hillside from the mine into a settling basin and on to treatment cells where limestone is used to raise the water's pH. At a higher pH, iron and other minerals drop out of solution, which means that these harmful precipitates stay in the settling basins rather than flowing into the creek.

Greetings from Sky-Vue Drive-In takes students on a tour through the history of drive-in theaters and a visit to one that's still open and thriving in Winchester, Kentucky. Looking at shadows through the drive-in movie projector introduces the relationship of a shadow's size to its distance from the light source.

Points of Origin

This animation from KET illustrates how an origin is used for positive and negative measurement along a straight line and on a flat plane. It also shows how an origin, latitude, and longitude identify locations on Earth and explores how measuring temperature differs from measuring height or weight.

In this video, staff members from Louisville Water Company explain the importance of groundwater, the widespread use of wells, and the riverbank filtration project's unique combination of a collection tunnel and a well system. The head engineer explains the many advantages of using such a system, which is then explored through an animated diagram.

This video traces the actual construction of Louisville Water Company's riverbank filtration system including the process of dynamiting the shaft and introducing the boring machine. It describes how this machine excavated 60,000 tons of rock, which was removed via a railcar system. It also highlights the unexpected discovery of a reservoir of prehistoric water and explores the tunnel workers' daily routine.

This full-length, uncut video showcases a massive riverbank filtration project undertaken by Louisville Water Company to provide clean tap water for customers. Along with engineers from the project, "Science Steve" and his animated sidekick Tapper explore related science and engineering topics, such as Ohio River geology, aquifers, and the function and structure of wells. The video also documents the construction of the tunnel and wells that make up the riverbank filtration system and illustrates the movement of water from the aquifer to the water treatment plant.

Tunneling for Water: Digging the Well and Treating the Water

This video examines the purpose and anatomy of a well and how it is drilled. Through a diagram of Louisville Water Company's riverbank filtration system, you see how water moves through the aquifer to the well and from the well to the tunnel via "well screens" that filter out particulates and channel the water to the tunnel. Finally the water is pumped to the water company where it chemically treated to produce safe drinking water.

Mycoremediation

Streaming icon

This video explores how planting fungi on the borders of parking lots helps mitigate non-point-source water pollution caused by leaking vehicles. After mulching an area at the lower end of the Bernheim Forest parking lot, staff members inoculated or planted the area with oyster mushrooms. Like other fungi, these mushrooms have mycelia, microscopic tubes always present in the soil, even when a mushroom's caps are not visible. When rain washes the oil and gas present on the parking lot into this area, the mycelia break the hydrocarbon molecules into less toxic compounds. This use of fungi to prevent non-point-source water pollution is called "mycoremediation."

Applying the Scientific Method

This video provides a real-life example of the scientific method: testing hypotheses about which plants will grow most successfully on a green roof in Kentucky. At Bernheim Forest near Louisville, scientists have set up 12 roof grids at ground level. The roof grids are filled with three different kinds of growing media and planted with four different groups of plants to determine which plants and media would work best for the Visitor Center roof garden and other roof gardens in the region.

Controlling Water Run-off

This video shows how the environmentally friendly design of the Visitor Center at Bernheim Arboretum and Research Forest near Louisville, Kentucky helps to control non-point-source water pollution, conserve water, and prevent erosion by slowing down and collecting water run-off. The video examines the sources of non-point-source water pollution, the structure and function of a green roof, using a reservoir to collect water, and the structure and function of a French drain and a cistern.
