In May 2000, the unthinkable happened; individuals living in Canada became ill, some fatally, from drinking tap water contaminated with a toxic strain of Escherichia coli (e-coli). Walkerton, a small rural town in Ontario, Canada, was thrust into the spotlight as Canadians tried to understand how this could have happened. A public inquiry was struck to investigate the causes of the tragedy and make recommendations to ensure that it would not happen again. As a result, governments across Canada are taking a close look at how drinking water supplies are protected and managed.

One of the more daunting tasks facing environmental practitioners over the past decade or two has been the recovery of cleanup costs and related relief at sites contaminated with petroleum substances. Parties seeking relief face significant hurdles under the federal environmental statutes. The key federal environmental cost-recovery statute, the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) often provides little help because of its petroleum exclusion.

Editors' Summary: Pfiesteria piscicida, a sometimes toxic microorganism, is responsible for the death of millions of fish in Delaware, Maryland, North Carolina, and Virginia. Although the problem of Pfiesteria-related fish kills is associated with the Mid-Atlantic region, other toxic microorganisms have threatened fish and marine wildlife throughout the world. Scientists attribute this "global epidemic" of toxic microbes to excessive nutrient loading from nonpoint sources of pollution.

Water scarcity is no longer a threat, it is a reality. Increasing populations throughout the country and the world are putting increased pressure on existing supplies of freshwater. Cities, states, and regions are scrambling to find solutions to this burgeoning problem. The impact of drought, which has been felt not only in the typically dry Southwest, but also in the humid Southeast this past summer, compounds the problem. So, what mechanisms evolve to help alleviate the problem?

Buried deep within the several thousand page Omnibus Consolidated Appropriations Act signed by President Clinton in the waning days of the 104th Congress are the first significant amendments in a decade to the much-debated Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA or Superfund). CERCLA is the federal law that creates a broad class of parties potentially liable for expenses incurred in cleaning up sites contaminated with hazardous substances.

Editors' Summary: This Article is the last in a three-part series intended to supplement Federal Wetlands Law, a primer that ELR published in 1993 and subsequently incorporated into the Wetlands Deskbook. The Article, which refers to the primer but stands on its own, focuses primarily on where wetlands law has changed since the primer's publication. The Article first addresses judicial review of agency wetlands decisions, including a proposed administrative appeal process for U.S.

Congress will be returning to Washington about the time this Dialogue is published. The Superfund reauthorization bill that did not pass in the last Congress is the natural starting point for the renewed discussion in this Congress of Superfund's reauthorization. This Dialogue is about that upcoming reauthorization and has two purposes.

Editors' Summary: During congressional debate on CERCLA reauthorization, attention has focused on the role of states in executing the Act. Some observers of these debates have questioned the constitutionality of delegating EPA cleanup and enforcement authorities to states. In contrast, this Article argues that such delegation is permissible under the U.S. Constitution and constitutional jurisprudence. The author asserts that under the Appointments Clause, the delegation of CERCLA authorities to states would not usurp Executive Branch functions.

Editors' Summary: The enactment of CERCLA in 1980 sparked an explosion of contentious litigation between EPA and potentially responsible parties (PRPs) concerning the liability of PRPs under the Act. After over a decade of litigation in which EPA usually emerged victorious, the focus of CERCLA litigation has shifted to secondary suits between PRPs for cost recoupment, contribution, and insurance coverage, and, consequently, new issues have arisen. This Article examines the issues that dominate the emerging case law for secondary CERCLA suits.

Editors' Summary: CERCLA §107 contains a third-party affirmative defense provision for owners of hazardous waste sites who exercised due care. Despite the abundance of CERCLA litigation, until recently no clear understanding of due care had yet emerged. But now, a series of New York federal court opinions suggest that due care turns on the owner's actions at the time the owner becomes aware of the contamination. This Article surveys the due care case law and focuses on the recent New York decisions.
