Treatment Options for High EDB Levels

Activated Carbon Filtration

Activated carbon filtration is an effective method to remove EDB from well water. It works by treating the water with activated carbon, which adsorbs and traps the EDB contaminants, thereby reducing their concentration.

Reverse Osmosis

Reverse osmosis systems can also be used to remove EDB from well water. This method utilizes a semipermeable membrane to separate the EDB molecules from the water, resulting in clean and safe drinking water.

Distillation

Distillation is a process that involves heating the water to create steam and then condensing the steam to produce purified water. This method effectively removes EDB and other contaminants that may be present.

Aeration

Aeration, or air stripping, is another treatment option for EDB removal. This process introduces air into the water, causing the EDB to volatilize and escape into the air, leaving the water free from contamination.

Prevention and Mitigation Strategies

Proper Well Construction and Maintenance

One of the key preventive measures to reduce the risk of EDB contamination is to ensure proper well construction and maintenance. Regular inspections, maintenance of well caps, and proper sealing of wells can help prevent potential sources of contamination from entering the water supply.
