Brookhaven National Laboratory's Kenneth Johnson inspects one of two modular aeration system tanks at the Laboratory's sewage treatment plant. The Laboratory completed an upgrade of the plant from primary to tertiary treatment, which reduces organic material and nitrogen, thereby minimizing the nutrients discharged to the Peconic River. In addition, the effluent is now disinfected with ultraviolet light, eliminating the use of chlorine. Operating since 1969 under a New York State permit, the plant treats about one million gallons of effluent each day, which is discharged into the dry riverbed of the Peconic River on the Lab site. Hendrickson Brothers, Inc., of Farmingdale, Long Island, completed the upgrade project at a cost of $3.25 million.
