providing one or more injection wells located upstream of the contaminated site in the flow of groundwater to the contaminated site;
directing groundwater to flow through the one or more injection wells prior to flowing through the contaminated site;
dissolving a chemical oxidant in the groundwater as the groundwater flows through the one or more injection wells;
dispersing the groundwater with dissolved chemical oxidant for flow through the contaminated field; and
allowing the ground water with the dissolved chemical oxidant to flow through the contaminated field, the dissolved chemical oxidant reacting with and treating the contaminated site.
2. The method of claim 1 wherein the chemical oxidant is potassium permanganate.
3. The method of claim 1 wherein the step of directing the water to flow through the injection wells comprises installing first baffles upstream of the one or more injection wells.
4. The method of claim 3 wherein the first baffles are angled to direct groundwater flow through the one or more injection wells.
5. The method of claim 1 further comprising monitoring the treatment by testing groundwater downstream of the contaminated site.
6. The method of claim 1 wherein the step of dispersing the groundwater with dissolved chemical oxidant comprises installing second baffles between the one or more wells and the contaminated site for dispersing water.
7. The method of claim 6 wherein the second baffles are oriented perpendicular to the direction of groundwater flow.
8. The method of claim 1 further comprising increasing groundwater flow from the one or more wells by pressurizing the one or more wells.
9. The method of claim 8 wherein the one ore more wells are pressurized by injecting air into the wells.
10. The method of claim 8 wherein the one or more wells are pressurized by injecting water into the one or more wells.
11. An apparatus for treating a contaminated site including soil and groundwater comprising:
at least one injection well positioned upstream of the contaminated site;
a chemical oxidant injected within the at least one injection well;
means for directing groundwater to flow through the at least one injection well to pick up the chemical oxidant; and
means for dispersing the groundwater with chemical oxidant to flow through contaminated site.
12. The apparatus of claim 11 wherein the chemical oxidant comprises potassium permanganate.
13. The apparatus of claim 12 wherein the chemical oxidant comprises pellets.
14. The apparatus of claim 12 wherein the chemical oxidant comprises powder.
15. The apparatus of claim 11 wherein the means for directing groundwater flow through the at least one injection well comprises first baffles positioned upstream from the wells to funnel groundwater flow into the wells.
16. The apparatus of claim 15 wherein the means for dispersing the groundwater comprises second baffles positioned in the ground between the wells and the contaminated site.
17. The apparatus of claim 16 wherein the second baffles are positioned perpendicular to the flow of groundwater.
18. An injection well for delivering an oxidant to a site including contaminated soil and groundwater comprising:
a sump partially embedded in bedrock;
a screened interval interconnected with the sump;
a well riser interconnected with the screened interval and extending from the screened interval to ground surface; and
a cover positionable over the well riser.
19. The injection well of claim 18 wherein the screened interval extends approximately five feet from the sump.
20. The injection well of claim 18 wherein the sump comprises a pipe with a bottom end cap.
21. The injection well of claim 18 further comprising means for pressurizing the well.
22. The injection well of claim 21 further comprising a pressure gauge for monitoring and maintaining pressure in the injection well.
23. A method for treating a contaminated site comprising:
providing an injection well upstream of the contaminated site;
introducing a solid chemical oxidant into the injection well;
allowing groundwater to flow into the injection well;
dissolving the chemical oxidant into the groundwater;
allowing the groundwater with dissolved chemical oxidant to flow out of the injection well; and
allowing the dissolved chemical oxidant to treat the contaminated site.
24. The method of claim 23, wherein the chemical oxidant is potassium permanganate.
25. The method of claim 24 wherein the chemical oxidant is in pellet form.
26. The method of claim 25 wherein the chemical oxidant is in powder form.
27. The method of claim 23, further comprising:
sampling the groundwater downstream of the contaminated site; and
selectively increasing or decreasing the amount of chemical oxidant in the injection well based on the results of the sampling.
28. The method of claim 23 further comprising directing the groundwater to flow into the injection well by installing baffles upstream of the injection well.
29. The method of claim 28 further comprising dispersing the groundwater with dissolved chemical oxidant by installing a second baffle between the injection well and the contaminated site.
