Evergreen has considered and will continue to consider various remedial options at each area of proposed remediation. Remedial options must consider a number of factors, including but not limited to logistics, utilities, subsurface flow conditions, chemistry, nature and extent of the contamination, nutrient availability, etc. Bioremediation technologies, not specifically mycoremediation, have been/are utilized in AOI-4 and AOI-1 and will continued to be considered for the Site.
