Alkaline precipitation

Alkaline precipitation occurs due to natural and anthropogenic causes. It happens when minerals, such as calcium, aluminum, or magnesium combine with other minerals to form alkaline residues that are emitted into the atmosphere, absorbed by water droplets in clouds, and eventually fall as rain. Aquatic environments are especially impacted by alkaline precipitation. Because alkaline precipitation can be harmful to the environment, it is important to utilize various methods such as air pollution control, solidification and stabilization, and remediation to manage it.[1]

The impact of alkaline residue in the environment. Industrial processes produce alkaline residue that leaks into the environment such as groundwater changing the pH or can become fugitive dust in the air.[1]
