Abstract
Certain exemplary embodiments can provide a composition of matter adapted for and/or resulting from, a method that can comprise and/or relate to, activities comprising treating contaminated groundwater via mixing a polymer with a cross-linking agent and/or an oxidant and delivering the mixture to contaminated groundwater to form an in situ controlled-release composition.
Claims16
A method of treating contaminated groundwater in situ, the method comprising the activities of:
- mixing polyvinyl acetate with a permanganate salt to form a mixture;
- introducing the mixture into the contaminated groundwater to form a cross-linked polyvinyl acetate network in the mixture;
- forming in situ, from the mixture and the contaminated groundwater, a controlled-release oxidant composition;
- and
- wherein the permanganate salt and the polyvinyl acetate are selected in amounts so that the controlled-release oxidant composition releases
- the permanganate salt into the contaminated groundwater for a period of at least 6 months.
A method for in situ treatment of contaminated groundwater, the method comprising the activities of:
- mixing polyvinyl acetate with a cross-linking agent and an oxidant to form a mixture;
- introducing the mixture into the contaminated groundwater to form a cross-linked polyvinyl acetate network in the mixture;
- forming in situ, from the mixture and the contaminated groundwater, a controlled-release oxidant composition;
- and
- releasing the oxidant from the controlled-release oxidant composition into the contaminated groundwater for a period of at least 6 months.
