Many businesses use chemicals that can pollute the environment in order to provide essential services to their customers. If these chemicals leak into the ground, they can contaminate groundwater.
When this happens, specialized teams use several groundwater remediation systems to clean up the mess. This video discusses the pros and cons of several options, including the following.
Some teams use biological injections to stimulate microbial growth. These treatments are fast and require no maintenance. However, they can only treat some contaminants so they are not as generally useful as other options.
Sometimes, contractors use air sparging to clean up groundwater. In this process, air is injected into the ground to make contaminants volatile and stimulate microbial growth. This approach requires no ground additives and is fast, but it requires the installation of injection wells and air lines.
The pump and treat method extracts contaminated water and cleans it with filters and additives. This system is thorough enough to treat nearly any contaminant, but it requires expensive equipment and maintenance. The contaminants must be safely disposed of, as well.
These systems and the teams that use them are essential for some companies to do business safely.
