With no explanation, chose the best option from "A", "B", "C" or "D". hazardous substances found at the site are also found in the defendant’s waste. There appeal's to be some confusion in the parties’ briefs regarding the issue of causation under CERCLA. Where, as here, a plaintiff is seeking recovery from numerous generator potentially responsible parties (“PRPs”), “the issue of causation would involve a factual determination of not whether defendants hazardous waste caused response costs, but, rather, whether a release or threatened release caused plaintiffs to incur response costs.” Arizona v. Motorola, 805 F.Supp. 742, 746 (D.Ariz.1992). Thus, Acme is not required to show that any particular “fast-track” defendant’s waste was the cause or a cause of the release. See, e.g. Dedham Water Co. v. Cumberland Farms Dairy, 889 F.2d 1146, 1157 (1st Cir.1989) (<HOLDING>); United States v. Ottati & Goss Inc., 630
