The present invention relates to compositions and methods that are effective in the remediation of contaminants found in natural sources such as groundwater, surface water, soil and manufactured products. The disclosed compositions and methods provide a method for remediating chlorinated polyaromatic compounds by treating them under pressure and heat with concentrated acids and chloride salts. After decomposition has occurred, the resulting acid that is produced is made dermal and non-corrosive. The compositions and methods claimed herein make the product safe to be in contact with humans and animal tissue without causing injury.

1. A composition that is effective in the remediation of chlorinated polyaromatic compounds, said composition comprising a mixture of hydrochloric acid, chloride salt and water, wherein said composition has a pH of less than 2.0 when the mixture is present at a concentration of 0.1% by weight and a
1. A composition that is effective in the remediation of chlorinated polyaromatic compounds, said composition comprising a mixture of hydrochloric acid, chloride salt and water, wherein said composition has a pH of less than 2.0 when the mixture is present at a concentration of 0.1% by weight and a proton count ranging from 2.0×1024 to 4.5×1024 when the mixture is present at a concentration of 1% by weight. 2. The composition of claim 1, wherein the chlorinated polyaromatic compound is a polychlorinated biphenyl. 3. The composition of claim 1, wherein the chloride salt is selected from ammonium chloride, sodium chloride, potassium chloride, calcium chloride, magnesium chloride, aluminum chloride, zinc chloride, nickel chloride, lead chloride, ferrous chloride, ferric chloride, gold chloride and combinations or mixtures thereof. 4. A method for the remediation of chlorinated polyaromatic compounds comprising the steps of: a) mixing concentrated hydrochloric acid with water to cause an exothermic reaction;b) mixing an amount of a composition comprising at least one chlorinated polyaromatic compound to the mixture of hydrochloric acid and water in step a);c) subjecting the chlorinated polyaromatic compound and acid mixture of step b) to increased pressure, thereby increasing the temperature of the mixture to at least 600° C.;d) maintaining the temperature of the mixture of step c) at or above 600° C. for at least 120 seconds; ande) adding a chloride salt to the chlorinated polyaromatic compound and acid mixture of step d). 5. The method of claim 4, wherein the initial mixture of hydrochloric acid and water is maintained at a temperature of at least 60° C. 6. The method of claim 4, wherein the temperature of the initial mixture of hydrochloric acid and water ranges from 60° C. to 65° C. 7. The method of claim 4, wherein the chlorinated polyaromatic compound and acid mixture is maintained at a temperature of at least 600° C. for at least 60 seconds. 8. The method of claim 4, wherein the chlorinated polyaromatic compound and acid mixture is maintained at a temperature of at least 600° C. for at least 120 seconds. 9. The method of claim 4, wherein the chlorinated polyaromatic compound and acid mixture is maintained at a temperature of at least 650° C. for 60 seconds to 120 seconds. 10. The method of claim 4, wherein the temperature of the chlorinated polyaromatic compound and acid mixture is increased from a starting temperature of at least 60° C. to at least 600° C. 11. The method of claim 10, wherein the temperature of the chlorinated polyaromatic compound and acid mixture is increased by subjecting the mixture to increased pressure. 12. The method of claim 11, wherein the pressure of the chlorinated polyaromatic compound and acid mixture is increased from atmospheric pressure to a pressure ranging from 980 kPA to 1150 kPA. 13. The method of claim 4, wherein the chloride salt is added to the chlorinated polyaromatic compound and acid mixture at a concentration of 5% to 30% by weight of the hydrochloric acid. 14. The method of claim 4 wherein, the chloride salt is selected from ammonium chloride, sodium chloride, potassium chloride, calcium chloride, magnesium chloride, aluminum chloride, zinc chloride, nickel chloride, lead chloride, ferrous chloride, ferric chloride, gold chloride and combinations or mixtures thereof. 15. The method of claim 4, wherein the composition comprising at least one chlorinated polyaromatic compound is added to the mixture of hydrochloric acid and water at a concentration of 35 parts to 150 parts of the composition to 1 part of hydrochloric acid and water. 16. The method of claim 15, wherein the ratio of chlorinated polyaromatic compound to acid ranges from 50-125:1. 17. The method of claim 15, wherein the ratio of chlorinated polyaromatic compound to acid ranges from 75-100:1.
