Perchlorate removal from ground water

Patent Granted Perchlorate is a toxic byproduct of the production of a rocket fuel and fireworks. Low levels of perchlorate have been detected in both drinking water and groundwater in 26 states in the U.S., according to the Environmental Protection Agency. In 2004, the chemical was also found in cow's milk in California with an average level of 1.3 parts per billion ("ppb" or µg/L), which may have entered the cows through feeding on crops that had exposure to water containing perchlorates.[11] According to the Impact Area Groundwater Study Program, the chemical has been detected at levels as high as 5 µg/L in Massachusetts, well over the state regulation of 2 µg/L.[12] Fireworks are also a source of perchlorate in lakes
