Bertha owns land located outside Centre City. Bertha sells the land to Disposal & Recycling, Inc., which establishes a hazardous waste disposal facility at the site. Disposal & Recycling accepts only waste transported by Eco Trucking Inc. exclusively from Federated Industries, Inc. Several years later, Disposal & Recycling closes its facility and sells the land to Garden Variety Retail Corporation, which builds a Home & Yard store on the site. Meanwhile, some of Centre City’s citizens complain to the Environmental Protection Agency (EPA) that the city’s municipal water supply is polluted. The EPA investigates and discovers that the sources of the pollution are leaks of hazardous waste from what is now the Home & Yard site. The EPA cleans up the site. Who can be held liable for the cost of cleaning up the site? What standards must Centre City meet regarding the water?
