Using contaminated groundwater causes hazards to public health through poisoning or the spread of disease, and the practice of groundwater remediation has been developed to address these issues. Contaminants found in groundwater cover a broad range of physical, inorganic chemical, organic chemical, bacteriological, and radioactive parameters.
Groundwater pollution (also called groundwater contamination) occurs when pollutants are released to the ground and make their way into groundwater.This type of water pollution can also occur naturally due to the presence of a minor and unwanted constituent, contaminant, or impurity in the groundwater, in which case it is more likely referred to as contamination rather than pollution.
The residence time is the time that the contaminated groundwater will spend in the treatment zone for decontamination. Contamination outside the capture zone or that does not have a long enough residence time will not be properly decontaminated. Groundwater modeling can also be used for the following:
Groundwater treatment systems will be installed near a military base in northern Michigan to address contamination from high levels of toxic, widely used “forever chemicals,” the U.S ...
Utilizing its innovative PlumeStop ® Colloidal Activated Carbon Technology, the company has successfully remediated over 72 million gallons of PFAS-contaminated groundwater, cleaning up more than 60 sites globally. This achievement was accomplished at less than a third of the cost of traditional methods and without generating any PFAS waste ...
The EPA said the facilities will treat groundwater in a part of the San Fernando Valley Superfund site, enabling the LADWP to use the water as part of its supplies.
Next month treatment of the groundwater contamination is expected to start with the injection of chemicals into the ground to bind to contaminants and stop their spread outside the landfill.
In January 2007, the groundwater around the Naval Air Station North Island in San Diego County, California was treated. This test treated a total of 60,000 gallons of groundwater and used about 22,646 pounds of sodium persulfate to do it. No catalysts were added to the persulfate, but there was a significant amount of contaminant reduction.
