This is a compilation in tabular form the EPA's national recommended water quality criteria for 157 pollutants, developed pursuant to section 304(a) of the Clean Water Act (CWA or the Act). These recommended criteria provide guidance for States and Tribes in adopting water quality standards under section 303(c) of the CWA. Such standards are used in implementing a number of environmental programs, including setting discharge limits in National Pollutant Discharge Elimination System (NPDES) permits. These water quality criteria are not regulations, and do not impose legally binding requirements on EPA, States, Tribes or the public. EPA's process for deriving new and revised 304(a) criteria are also described. This document is in PDF format.
This volume describes the methods used in the surveillance of drinking water quality in the light of the special problems of small-community supplies, particularly in developing countries, and outlines the strategies necessary to ensure that surveillance is effective.

Environmental Protection: Law and Policy, respected for its intellectual breadth and depth, is an interdisciplinary overview of Environmental Law, incorporating history, theory, litigation, regulation, policy, science, economics, and ethics. It covers the history of environmental protection; policy objectives; regulatory design strategies; and constitutional federalism?and related statutory interpretation issues concerning the design and implementation of the environmental laws. Coverage also includes the Clean Air Act, the Clean Water Act, the Resource Conservation and Recovery Act, CERCLA, and other pollution control statutes; a chapter on climate change?that discusses scientific, policy, program design, and statutory authority questions; and natural resource management issues (including the National Environmental Policy Act, the Endangered Species Act, and limited coverage of national forest management). New to the 9th Edition: New co-author Alejandro Camacho, a leading scholar on natural resources and public land law Ch.1: New materials on the Flint, Michigan battles over lead contamination of the municipal water system Ch.2: Discussion of regulatory and judicial skirmishes resulting from policy differences among the Obama, Trump, and Biden administrations Ch.3: Changes, driven by the Supreme Court, to areas such as standard of judicial review (including the Court’s endorsement of the major questions doctrine) and potential changes to entrenched law in areas such as the nondelegation doctrine Ch.4: Council on Environmental Quality’s overhaul of its 1978 NEPA regulations under the Trump administration and the Biden CEQ’s phased revision of those regulations; Food and Water Watch v. FERC; Sierra Club v. EPA Ch.5: Discussion of recent research and scholarship on biodiversity loss, the Trump administration’s efforts to restrict the scope of the Endangered Species Act, and the Biden administration’s attempts to reverse or revise these changes; recent developments on listing, critical habitat, federal agency consultation, taking prohibitions, and incidental takings Ch.6: Updated references to air pollution science Ch.7: Updates on ongoing litigation involving the “waters of the United States” definition in the Clean Water Act Ch.8: EPA’s efforts to implement 2016 amendments to the Toxic Substances Control Act; League of United Latin American Citizens v. Regan Ch.9: New case law under CERCLA; discussion of the treatment in the Restatement (Third) Torts of joint and several liability Ch.10: Streamlined coverage of environmental enforcement process Ch.11: Updated coverage of climate change law, policy, and science to reflect opposed regulatory responses to climate change by the Trump and Biden administrations; West Virginia v. EPA Online environmental justice supplement Streamlined note material Benefits for instructors and students: Thorough, nuanced treatment of existing laws, regulations, and cases, regulatory design strategies, and current and developing policy objectives Interdisciplinary approach incorporating science, economics, and ethics Coverage of major federal pollution control, environmental assessment, and species protection laws Charts and graphics Exercises and problems Distinguished author team with extensive practical, scholarly, and teaching experience
Environmental problems in coastal ecosystems can sometimes be attributed to excess nutrients flowing from upstream watersheds into estuarine settings. This nutrient over-enrichment can result in toxic algal blooms, shellfish poisoning, coral reef destruction, and other harmful outcomes. All U.S. coasts show signs of nutrient over-enrichment, and scientists predict worsening problems in the years ahead. Clean Coastal Waters explains technical aspects of nutrient over-enrichment and proposes both immediate local action by coastal managers and a longer-term national strategy incorporating policy design, classification of affected sites, law and regulation, coordination, and communication. Highlighting the Gulf of Mexico's "Dead Zone," the Pfiesteria outbreak in a tributary of Chesapeake Bay, and other cases, the book explains how nutrients work in the environment, why nitrogen is important, how enrichment turns into over-enrichment, and why some environments are especially susceptible. Economic as well as ecological impacts are examined. In addressing abatement strategies, the committee discusses the importance of monitoring sites, developing useful models of over-enrichment, and setting water quality goals. The book also reviews voluntary programs, mandatory controls, tax incentives, and other policy options for reducing the flow of nutrients from agricultural operations and other sources.
A stand-alone working document, Stormwater Effects Handbook: A Toolbox for Watershed Managers, Scientists, and Engineers assists scientists and regulators in determining when stormwater runoff causes adverse effects in receiving waters. This complicated task requires an integrated assessment approach that focuses on sampling before, during, and aft
