The United States has the most laws regarding environmental safety and health. The National Environmental PoHcy Act (NEPA) of 1969 has resulted in the following acts Eederal Insecticides, Eungicide and Rodenticide (EIERA), Resource Conservation and Recovery (RCRA), Superfund (CERCLA), Superfund Amendments and Reauthori2ation Act (SARA) Plus Tide III, Toxic Substance Control Act (TSCA), Clean Water (CWA), Water Quahty, Safe Drinking Water (SDWA), and Waste Minimi2ation and Control. 

Today resource limitations have caused the United States Environmental Protection Agency (USEPA) to reassess schedules for new rules. A 1987 USEPA survey indicated there were approximately 202,000 public water systems in the United States. About 29 percent of these were community water systems, which serve approximately 90 percent of the population. Of the 58,908 community systems that serve about 226 million people, 51,552 were classified as "small" or "very small." Each of these systems at an average serves a population of fewer than 3300 people. The total population served by these systems is approximately 25 million people. These figures provide us with a magnitude of scale in meeting drinking water demands in the United States. Compliance with drinking water standards is not... 

AAC = acceptable ambient concentration ACGIH = American Conference of Governmental Industrial Hygienists ADEQ = Arizona Department of Environmental Quality SNA = Bureau of National Affairs CDC = Center for Disease Control CERCLA = Comprehensive Environmental Response, Compensation, and Liability Act CFR = Code of Federal Regulations DNR = Department of Natural Resources DWEL = drinking water equivalent level ... 

The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA)1-3 and the Superfund Amendments and Reauthorization Act (SARA)1 2 4 protect the public from the risks created by past and recent chemical disposal practices. Cleanup of contaminated sites is needed in order to protect human and natural resources, as defined by the Clean Air Act,5 the Clean Water Act,6 the Safe Drinking Water Act,7 and the Resource Conservation and Recovery Act (RCRA)89...

Freshwaters are an essential resource which must be available not only in the required quantity but also in a precise quality. Nevertheless, in the last years, this quality has been threatened as a consequence of the increasing industrial activity, population growth and agricultural practices. In fact, only less than 1% of the world s freshwater resources are readily available for human use, and even this resource is unevenly distributed among the countries. A lack of water to meet daily needs is a reality for many people around the world, and water scarcity already affects every continent. In the underdeveloped countries, water scarcity forces people to rely on unsafe sources of drinking water. In the developed countries, this problem is much less critical where contamination of drinking water is the adverse... 

Free cyanide criteria currently proposed for natural resource protection include <3 pg/L medium for aquatic life, and <100 mg/kg diet for birds and livestock. For human health protection, free cyanide values are <10 pg/L drinking water, <50 mg/kg diet, and <5 mg/m3 air. 

For maximum protection of human health from the potential carcinogenic effects of exposure to arsenic through drinking water or contaminated aquatic organisms, the ambient water concentration should be zero, based on the nonthreshold assumption for arsenic. But a zero level may not be attainable. Accordingly, the levels established are those that are estimated to increase cancer risk over a lifetime to only one additional case per 100,000 population. These values are estimated at 0.022 pg As/L for drinking water and 0.175 pg As/L for water containing edible aquatic resources (USEPA 1980 Table 28.7). 

The Missouri Department of Natural Resources and the EPA have sampled 77 former USDA/CCC grain storage facilities. Nine locations (12%) had detections of carbon tetrachloride, with four (5%) of these locations exceeding the drinking water standard of five micro grams per liter. 

Personnel. More than any other area, we are often asked "How many people has your corporation added due to TSCA " I don t know of anyone who has a concise answer to this question. Complicating the situation is the fact that the 1960 s and 1970 s saw a number of environmental and health laws go into effect the Clean Air Act, Clean Water Act, Occupational Safety and Health Act, Safe Drinking Water Act, Federal Water Pollution Control Act, TSCA, Federal Food, Drug and Cosmetic Act, Hazardous Materials Transportation Act, Federal Insecticide, Fungicide and Rodenticide Act, Resource Conservation and Recovery Act, and Comprehensive Environmental Response, Compensation and Liability Act, to mention the major ones. This mixture of acts, with some similarities of purpose, developing within a time span of 10-15 years, has made a variety of similar demands. It is not easy at this point to attribute the addition of staff support personnel to an individual law such as TSCA. The same observation is applicable to all corporate resources which have felt the effects of TSCA however, in order to... 

Drinking water intended for human consumption is the most protected foodstuff worldwide and thus many national and international regulations have been introduced to assure a safe drinking water supply. In general, drinking water must be of a quality that under no circumstances would present a hazard to human health. In many countries, such as Germany, standards for water resources that may be used for drinking water production are specified [1].
