Facing a state-mandated deadline that is 18 months away, the Downingtown Area Regional Authority Monday night approved a plan that relies on an outdated technology to remove phosphorus from the Downingtown sewage-treatment plant's waste water. The $128,000 project calls for the installation of a chemical treatment system that even the project's designers acknowledged was less than optimal. "The July 1991 deadline can be met . . . using a standard chemical-feed system, but this is rapidly becoming an archaic technology," said Craig Coker, manager of the municipal services department for Engineering-Science Inc., the firm that designed the plan and also operates the Downingtown facility.

A freight train derailed last night and two cars carrying phosphorus caught fire, spewing a giant plume of toxic fumes that forced about 2,500 residents of at least three small towns to leave their homes. No injuries were reported, officials said. The 32-car CSX train derailed at 7:55 p.m., 3 1/2 miles north of Crofton in western Kentucky, state police said. Two tank cars carrying phosphorus ignited, and a third phosphorus tanker derailed but was not burning, said Alvin Pollard, assistant director of the Christian County emergency center in Hopkinsville.

YORK, Pa. - The latest substance from the York sewage treatment plant isn't stinky sludge or bubbly wastewater. It's little white pellets, about the size of small seeds. And they promise not only environmental benefit but real money. The pellets are fertilizer, and a formulation that incorporates them, produced by an Allentown company, is being tested at Longwood Gardens in Kennett Square. The pellets are also being touted as a way for the plant to meet stricter environmental limits for discharge into nearby Codorus Creek - and ultimately, the Chesapeake Bay, which suffers from an excess of nutrients.

Amid a flurry of criticism, a NASA-funded team on Thursday backed off the more extravagant, textbook-changing claims they'd made about a bacterium that had allegedly substituted arsenic for phosphorus in its DNA. The original announcement, made at a NASA news conference Dec. 2, seemed to break a cardinal rule of biology that all organisms need some phosphorus to survive. NASA researchers claimed to have discovered an exotic organism in California's Mono Lake that lived instead on arsenic, thus broadening the types of life that may exist in the universe.

A derailed tank car containing white phosphorus exploded last night, spreading a cloud of poisonous fumes that injured at least 78 people and forced thousands of residents to flee for the second time in two days. Allan Franks, a spokesman for the Ohio Environmental Protection Agency, said all residents of Miamisburg, West Carrollton, Moraine and Miami Township - about 25,000 people - were ordered to leave their homes in the Dayton suburbs. "If we have to go door-to-door to evacuate people in the city, we will," one police officer said.

Do arsenic-tolerant bacteria redefine life, as some recent headlines pronounced? And why are people saying the finding increases the odds of finding aliens? After a much-ballyhooed NASA news conference Thursday, a number of biologists were also scratching their heads. NASA fellow Felisa Wolfe-Simon and colleagues found some microbes living at the bottom of California's Mono Lake, which has a high level of arsenic. The scientists took the microbes out of the lake and infused them with more arsenic.

MEMBERS of The Crossing, a Philadelphia professional chamber choir whose sound the New York Times has described as "lush" and "mesmerizing," sing a lot more than your typical Bach cantatas and oratorios. That's evident this weekend with the all-vocal "Hesperus is Phosphorus," the second concert in the group's fourth annual Month of Moderns series. The series fulfills conductor Donald Nally's initiative to commission new music for the group. This year's theme has been pieces related to or inspired by poetry; "Hesperus" draws from modern vespers.

We were sitting down to Christmas Eve dinner at the Seventh Surgical Hospital, Blackhorse Base Camp, Republic of Vietnam. The year was 1968. It was a quiet night in the war, and the doctors and nurses were looking forward to an evening eating turkey, exchanging presents and longing to be elsewhere. The bad news came, as it always did, from the night radio operator who appeared at the side of the hospital commander, whispering in his ear. "Ladies and gentlemen," the colonel said, "we have casualties coming in. " This group had heard these words before and quietly moved to the triage area.

FMC Corp., the industrial conglomerate from Chicago, said yesterday it will scale back some of its Philadelphia employment, pending government approval of a joint venture to be based in St. Louis. The company has 450 employees working for its chemical businesses at the Mellon Bank Center in Center City, but that is expected to decline after FMC and Solutia Inc., of St. Louis, combine their phosphorus and phosphate businesses. "It will involve a small percentage of our employees in Philadelphia," said Thomas Kline, a spokesman for FMC in Chicago, who said he could not specify the number of jobs that would be lost.
