Pres. and Hillary Rodham Clinton have received a unique gift welcoming them to their new home in Chappaqua, N.Y.: a 76-page report listing 47 known or potential toxic sites within one mile of the house the couple is buying. The report, prepared by Toxics Targeting, an environmental research company in Ithaca, N.Y., was FedEx-ed to the White House this weekend, along with a map showing the location of the toxic sites. Local resident Marian H. Rose, conservation chair of the Sierra Club’s Atlantic Chapter: “People think of us as all pristine and pretty, but actually we’re pretty dirty up here.” Jim Kennedy, spokesperson for the White House Counsel’s Office, said the Clintons were “not aware of any specific environmental concerns regarding this home.”
