George Wants to Buy an Old Chemical Factory in the Warehouse

George wants to buy an old chemical factory in the warehouse district of town. He plans to take advantage of the upcoming neighborhood and turn the building into expensive lofts. After purchasing the property and starting renovations, he discovers that the land is contaminated with hazardous chemicals. He contacts the EPA to create a cleanup plan. When allocating liability and cleanup costs the EPA determines that George is:

A) not liable because he did not own the land when it was contaminated.
B) not liable because the chemical factory owners contaminated the property.
C) liable because he is the owner of the contaminated property.
D) liable because he should have conducted all reasonable inquiries into the previous ownership to determine whether any contamination was present.
