What Is Acid Mine Drainage In Cumbria

Introduction

Cumbria is a county in the North West of England known for its stunning landscapes, beautiful nature reserves, and rich history. The county is also home to a number of mines, many of which are no longer in use. However, these mines, despite no longer being active, pose a grave threat to the environment and have the potential to cause severe environmental damage.

What are Mines and Mine Drainage?

Mines are man-made structures designed to extract valuable minerals, ores, and metals from the earth's crust. The mining process involves the removal of rocks and soil, which is then processed to extract the valuable materials. The process generates unwanted by-products, including rock waste, mine tailings, and chemicals.

Mine drainage is the water that flows out of mines due to the mining process. It is often an alkaline or acidic solution, depending on the minerals it comes into contact with. Mining companies need to manage this water safely to prevent environmental damage.

What Is Acid Mine Drainage (AMD)?

Acid Mine Drainage (AMD) is a specific type of mine drainage that occurs when water comes into contact with minerals that contain sulfur. The process leads to the formation of sulfuric acid, which dissolves metals such as iron, aluminum, and copper.

The water that flows out of mines containing high levels of sulfuric acid is highly acidic and extremely hazardous. Acid mine drainage can cause severe environmental damage to streams, rivers, and aquatic life, and it can cause long-term damage to the ecosystem.

How Does AMD Form?

AMD is formed when water comes into contact with sulfide minerals, such as pyrite, which is an iron sulfide mineral. The interaction leads to the formation of sulfuric acid, which dissolves other minerals and potentially toxic elements such as arsenic, mercury, and lead.

The acid mine drainage can be prevented by adding substances that neutralize the sulfuric acid or by isolating the mine and redirecting the water before it has a chance to mix with the minerals.

AMD In Cumbria

Cumbria has a long history of mining, with coal, lead, and copper being the most prominent minerals extracted from the ground. The industrial revolution in the 19th century generated intense mining activity in the region. However, with the decline of the industry in the mid-20th century, many mines were closed down.

The mines, however, continue to pose a significant threat to the environment, with acid mine drainage being a significant concern. Many of these mines are abandoned, leaving behind pits and piles of toxic waste that continue to release acid mine drainage into the surrounding environment.

The Environmental Impact Of AMD

Acid mine drainage can be highly toxic to the environment, primarily when it comes into contact with water. AMD can be incredibly corrosive, breaking down rocks, and releasing metals and other toxins into the environment. This can kill aquatic life and significantly alter the chemistry of waterways.

In Cumbria, abandoned mines are responsible for polluting many of the county's rivers, streams, and groundwater. The pollution has led to the destruction of aquatic habitats and the death of fish, insects, and other aquatic life.

The Importance Of Reclamation

Reclamation is the process of restoring the land and waterways surrounding abandoned mines to their natural state. The goal of reclamation is to reduce the environmental impact of the mine and to restore habitats for the local flora and fauna.

Reclamation of disturbed land can prevent environmental damage by covering toxic waste with clean soil and re-introducing native vegetation. This process can stabilize the remaining piles of contaminated waste and prevent the release of AMD.
