Claim:
1. A method of remediating acidic waste products in media at a contaminated site, said method comprising: measuring acidity of the waste at the contaminated site; mapping measured acidity levels of multiple, distinct sub-plots of the contaminated site; calculating an amount of neutralization agent to raise the pH of the waste in the sub-plots to a pH range of 4.0 to 12.5; applying a first amount of neutralization agent to a first sub-plot of the contaminated site; mixing the first amount of neutralization agent into the first sub-plot of the contaminated site at a first depth; repeating applying and mixing at the first sub-plot of the contaminated site from the first depth to a first maximum depth; applying a second amount of neutralization agent to a second sub-plot of the contaminated site; mixing the second amount of neutralization agent into the second sub-plot of the contaminated site at a second first depth; repeating applying and mixing at the second sub-plot of the contaminated site from the second first depth to a second maximum depth; and neutralizing the pH of the acidic waste products in media at the contaminated site.
