Finally, the traffic volumes generated by the Library will not superimpose peaks on the existing volumes but rather occur on non-peak periods. Furthermore, in an effort to meet the modified EPA air quality standards, the City will have to work with regional agencies to change the existing traffic patterns. The increase in traffic due to the Library visitors is not likely to hamper such an effort...
...EPA found in later tests that New Orleans' drinking water, which comes from the Mississippi River, contained minute traces of 66 organic chemicals, some of them known carcinogens. (In New Orleans last week, there was a rush on bottled water, and city officials announced that they would investigate the water supply further.) Actually, the link between chlorination and the formation of these chemicals was confirmed abroad. J.J. Rook, a Dutch scientist, added chlorine to contaminated river water and to relatively pure lake water. The concentration of carbon tetrachloride and chloroform rose sharply in the polluted water...
More Study. The EPA quickly responded by ordering a two-part nationwide study of drinking-water supplies. The first phase will determine the concentration and potential effects of the various chemicals in U.S. drinking-water systems. After that, the possible sources of pollutants-mainly industrial discharges and agricultural runoffs -will be investigated, along with ways to eliminate them either at their source or in water-treatment plants...
Trouble with VC. Although the EPA's decision sets a precedent for protecting human health from potentially toxic substances, it hardly compares in impact to the action by the Labor Department's Occupational Safety and Health Administration (OSHA). The agency established final limits for workers' exposure to vinyl chloride (vc), a colorless gas derived from chlorine and petrochemicals. It is the major ingredient in polyvinyl chloride (PVC)-the material from which seat covers, phonograph records, credit cards, detergent containers, floor tiles, shower curtains, and a vast number of other familiar plastic products are made. In total...
...Environmental Protection Agency also got into the act, announcing that it will set air-pollution standards for vinyl chloride. A special EPA task force has found that more than 200 million Ibs. of vc and 50 million Ibs. of PVC are being discharged into the environment during the conversion process. In other words, people who live downwind of factories that make PVC might also unknowingly be getting a whiff of the gas. Two cases of angiosarcoma have in fact been reported in people whose houses were near a PVC plant in Bridgeport, Conn...
