States have made substantial recent progress in the adoption, and EPA approval, of toxic pollutant water quality standards. Furthermore, virtually all states have at least proposed new toxics criteria for priority toxic pollutants since Section 303(c)(2)(B) was added to the CWA in February 1987. Unfortunately, not all such state proposals address, in a comprehensive manner, the requirements of Section 303(c)(2)(B). For example, some states have proposed to adopt criteria to protect aquatic life, but not human health other states have proposed human health criteria that do not address major exposure pathways (such as the combination of both fish consumption and drinking water). In addition, in some cases final adoption of proposed state toxics criteria that would be approved by EPA nas been substantially delayed due to controversial and difficult issues associated with the toxic pollutant criteria adoption process. [Pg.15]

The small amounts of paint generated by the average household cannot be recycled economically, but most municipalities sponsor paint exchange programs and collect oil-based paints. Spent fuel rods from nuclear power plants can be recycled to reclaim unused uranium, and some spent uranium is used to produce armor-piercing bullets. Yard waste from households is often recycled and made into mulch for farming and gardening. Discarded Christmas trees are used to form mulch or are immersed in lakes as a habitat for fish.

Water Quality Standards. Water quaUty standards are usually based on one of two primary criteria, stream standards or effluent standards. Stream standards are based on dilution requirements for the receiving water quaUty based on a threshold value of specific pollutants or a beneficial use of the water. Effluent standards are based on the concentration of pollutants that can be discharged or on the degree of treatment required. [Pg.221]

In 1965 the Water Quahty Act established a new trend in water pollution control. It provided that the states set water quality standards in accordance with federal guidelines. If the states f ed to do so, the standards would be set by the federal government subject to a review hearing. In 1966, the Clean Water Restoration Act transferred the Feder Water Pollution Control Administration from the Department of Health, Education and Welfare to the Department of the Interior. It also gave the Interior Department the responsibility for the Oil Pollution Act. [Pg.2160]

Despite EPA s urging and guidance, state response was disappointing. A few states adopted large numbers of numeric toxic pohutant criteria, primarily for the protection of aquatic life. Most other states adopted few or no water-quality criteria for priority toxic pohutants. Some rehed on free from toxicity criteria and so-called acLion levels for toxic pollutants or occasionally calculated site-specific criteria. Few states addressed the protection of human health by adopting numeric human health criteria. [Pg.2160]

As indicated above, national policies and international conventions have been invoked to curb known, and usually obvious, sources of marine pollution. National legislation is used to control coastal discharges of contaminants. A major problem remains owing to the inadequate treatment of sewage prior to emission from land-based sources. The most important deleterious effects in this case are with respect to microbial water quality. This can have a direct influence on bathing criteria and result in beach closures during contamination episodes. An additional problem from land-based sources pertains to transboundary effects, whereby pollution may inadvertently be exported from one country to another. [Pg.89]

Pesticides are potentially poisonous, noxious or polluting substances, and therefore the NRA is responsible for controlling and preventing pesticide pollution of water. Furthermore, the NRA is responsible for ensuring water quality meets standards set in a number of EC Directives, some of which specify values for pesticides. [Pg.44]

Pollution The impairment (reduction) of water quality by agriculture, domestic or industrial wastes (including thermal and radioactive wastes) to such a degree as to hinder any beneficial use of the water or render it offensive to the senses of sight, taste, or smell or when sufficient amounts of waste creates or poses a potential threat to human health or the environment. [Pg.622]

Enormous amounts of waste dumped into water systems are degrading water quality and causing increased human health problems. In assessing this pollution, there are two distinct problem areas. The first, and worst, is in marine estuaries and associated coastal waters. As fewer and fewer alternatives remain for land disposal, wastes are finding their way more often into water. The second area consists of the oceans themselves, tiltliough it is believed tliat currently not much of a problem exists, because relatively little waste is dumped... [Pg.357]

A water body is considered to be a one-diiuensional estuary when it is subjected to tidal reversals (i.e., reversals in direction of tlie water quality parameter are dominant). Since the describing (differential) equations for the distribution of eitlier reactive or conserv ative (nomciictive) pollutants are linear, second-order equations, tlie principle of superposition discussed previously also applies to estuaries. The principal additional parameter introduced in the describing equation is a tid il dispersion coefficient E. Methods for estimating this tidiil coefficient are provided by Thomaim and Mueller... [Pg.361]

Much attention has been given in recent years to the environmental aspects of both the drilling operation and the drilling fluid components. Well-deserved concern with the possibility of polluting underground water supplies and of damaging marine organisms, as well as with the more readily observed effects on soil productivity and surface water quality, has stimulated widespread studies on this subject. [Pg.682]

Consultants are equipped to monitor the quality of freshwater, estuarine and marine environments and can make field measurements of a variety of water-quality parameters in response to pollution incidents. For example, reasons for the mortality of marine shellfish and farmed freshwater fish have been determined using portable water-analysis equipment. Various items of field equipment are, of course, also employed in baseline studies and monitoring, respectively, before and after the introduction of new effluent-disposal schemes. [Pg.40]
