Thank you for the informative and interesting series of articles on Long Island's groundwater. In "Composting and water" [News, Sept. 27], you presented evidence that composting sites are adding toxic levels of manganese to our drinking supply.
I'm concerned about the Islip Town compost facility situated south of the Ronkonkoma railroad station. This town-run facility had a high reading of 8,840 parts per billion, when 300 parts per billion is the accepted safe maximum.
I hope that Newsday follows up on this series, and lets the voting public know how Islip's officials deal with this situation.
