Due to a reporting error, the story, "Data center boom sparks environmental disputes in U.S.," which ran on the wire Monday, contained an incomplete description of the science the Department of Ecology used to find pollutant levels.

The 19th paragraph of the story on the wire has been corrected and now reads as follows:

Washington environmental authorities have taken air quality measurements in Quincy and said that while pollutant levels have gone up since the data centers were built, pollution levels are still much lower than would be found in nearby cities. The Department of Ecology has taken measurements for several years in Quincy. Department-generated computer models recently found that Intuit's diesel generators will give off the most exhaust.
