Abstract: A method of water treatment includes providing water that includes at least one contaminant. An effective amount of at least one filter media is added to the to the water that includes at least one contaminant. The water and the at least one filter media are agitated to form a homogeneous mixture. A cationic biopolymer is added to the homogeneous mixture of water and the at least one filter media. The water is separated from the at least one contaminant and the at least one filter media.

Abstract: A method of in-situ treatment of a body of water comprising at least one contaminant includes adding a blended water treatment substance to the body of water. The blended water treatment substance includes at least one geopolymer and at least one cationic biopolymer. The at least one contaminant is adsorbed from the contaminated water onto the geopolymer. The at least one geopolymer upon which the at least one contaminant is adsorbed is coagulated with the at least one cationic biopolymer. The coagulated at least one geopolymer, at least one biopolymer, and at least one contaminant is precipitated to settle within the water body.
