"Federal officials are worried that the fabled water â€" coming from the largest unfiltered system in the country â€" is getting muddier and may have to be completely filtered, at a cost of billions of dollars, if it cannot be kept clean."

"Turbidity â€" the condition that makes water cloudy and interferes with chlorination to eliminate contaminants â€" appears to be getting worse because of changing weather patterns and increasing runoff from land development upstate. If the city cannot find a permanent solution to the silt, it may not be able to avoid building a huge filtration plant that could cost about $8 billion."
