Coal mining involves blasting, excavating, and removing layers of earth to access coal seams, which can potentially disrupt natural drainage patterns and lead to contamination of water sources. The use of chemicals such as sulfuric acid in the process of extracting coal can also lead to pollution of nearby waterways.

Fracking, or hydraulic fracturing, is a method used to extract natural gas from underground shale formations. This process requires large amounts of water mixed with chemicals to be injected into the ground at high pressures to release the natural gas. In addition to potential air pollution concerns, fracking has also been linked to water contamination in some areas. The use of large quantities of water mixed with chemicals can potentially contaminate groundwater sources through spills, leaks, or inadequate waste disposal practices.

In Missouri, there have been cases where residents living near coal mines have reported issues with polluted drinking water. For example, residents near the West Lake Landfill site in St. Louis County have been dealing with contaminated groundwater caused by radioactive material from nuclear weapons manufacturing being illegally dumped there decades ago along with coal ash residue from a nearby landfill.

Similarly, concerns about fracking’s impact on water quality have emerged in some parts of the state. In 2019, a group representing landowners and environmentalists filed a lawsuit against an energy company for dumping wastewater from fracking operations into rivers that eventually flow into drinking water supplies for cities downstream.

Aside from direct impacts on local drinking water supplies, natural resource extraction activities can also lead to pollution or disruption of aquatic ecosystems in lakes and streams that support wildlife habitats and recreational activities like fishing and boating. In some cases, the use of chemicals in resource extraction can also lead to long-term contamination of water sources and result in negative impacts on public health.

In response to these concerns, Missouri has implemented regulations and monitoring requirements for coal mining and fracking operations to help mitigate their impact on water quality. However, the potential for pollution remains an ongoing concern as the state continues to rely on these industries for energy production.
