If these chemicals leak into the ground, they can be a source of contamination for groundwater. Groundwater remediation teams can be able to remove the contamination using several systems. The video discusses the advantages and cons of various options that include the following. Some teams use biological injections in order to encourage microbes to grow. They’re quick and do not require any need for maintenance. However, they are not capable of treating all pollutants and therefore may not provide the same benefits as alternative options. Contractors may use air sparging as a method to drain groundwater. In this process, air is injected into ground in order to turn the contaminants into a gas and encourage microbial growth. The method does not require any ground amendments or chemicals and can be done quickly and easy, however it involves the setting up of wells for injection and air lines. The pump and treat method is a method of removing contaminated water and cleaning it using filters and other additives. While this method can handle almost any type of contaminant it’s costly to keep and requires extensive equipment. The contaminants must be safely removed, and also. These systems and the teams they work with are necessary in order for businesses to run their operations in safety. tieiparua6.
