Environmental standards water pollution

The problem has been recognized by many of the developers concerned, who have consequently themselves adopted the environmental standards of other industrialized nations. In the absence of national controls this is a responsible and laudable approach. However, the piecemeal adoption of standards taken from elsewhere does not take account of local conditions. These conditions may either enhance or limit the ability of the environment to disperse and attenuate or assimilate pollutants (e.g. the occurrence of temperature inversions will limit the dispersion of air pollutants). Similarly, the use to which local resources are put may demand particularly high standards of environmental quality (e.g. the use of sea water or river water as the basis of potable water supply). The choice of standards must also take into account local practices and existing local administration.

In most countries, environmental regulation of chemicals started with the introduction of emission standards. The air pollution control law and the water pollution control law were typical examples of this type. 

Accurate and precise identifications and measurements of specific chemical substances are fundamental to environmental studies and protection programs. Determinations are required to understand natural background concentrations of chemicals in the environment, the nature and extent of environmental pollution by anthropogenic chemicals, trends in concentrations of these substances, the transport and fate of chemical substances, and the causes of variations of concentrations intime and space. Accurate and precise determinations are also required to assess human health and ecological risks caused by exposure to natural and anthropogenic substances, establish air and water quality standards, develop pollution control strategies, evaluate the effectiveness of pollution prevention and treatment technologies, and monitor compliance with and the effectiveness... 

As was the case in air-pollution research, in water pollution work the largest concern is the monitoring of the environment to determine if contamination is occurring and to follow the subsequent reduction of the level of problematic substances. As was mentioned earlier, PAHs are of environmental concern and, as such, are being monitored in air and water. Figure 2-14 shows the HPLC analysis of a National Bureau of Standards (NBS) sample of...

The environmental issues—increasingly tighter restrictions on water, air, land, and noise pollution—have forced management to reconsider existing operations as well as future investments. It is a simple matter to determine the capital requirements to meet the current and projected future environmental standards, but the benefits are manifested in continued operation and community recognition of a company s good citizenship.

The theoretical principles that underlie GC is presented in Chapter 4 and in numerous texts and monographs (see Ref. 3 for several examples). Specific methods that incorporate GC as the determinative instrumental technique are to be found in a plethora of analytical methods published by the Environmental Protection Agency (EPA), the American Public Health Association/American Water Works Association/Water Pollution Control Federation Standard Methods for the Examination of Water and Wastewater), and the American Society for Testing Materials ASTM, Part 31 Water). 

The EPA, like any other regulatory agency, sets standards (laws) and then checks to see that the laws are obeyed. It must enforce the Clean Air Act, the Clean Water Act, and Resource Recovery and Conservation Act (solid waste control). One way it does this is by monitoring industrial sites to determine if the site is deliberately releasing pollutants into the environment. Operators, instrumentation and analyzer technicians, and maintenance personnel working in refineries, petrochemical, and manufacturing plants are responsible for the proper operation of their equipment and proper performance of their duties so as to keep their facility in compliance with environmental standards. These employees will receive training on...
