The board for Pittsburgh Water and Sewer Authority unanimously approved the purchase of nearly a million dollars in equipment to remove the chemical trihalomethane from drinking water.

The chemical, a carcinogen, results when bromide reacts with chloride during the water disinfection process. Higher levels of bromide have been seen in the area's rivers, a result of a resurgence in industry along the river.

One tank -- at the Brashear facility -- already has the PAX Mixing system in a pilot program and has to be paid for. It will cost the authority around $220,000. Mixing systems will be installed at facilities in Allentown and Squirrel Hill. The price is still being negotiated, but the board approved the purchase and installation of the two mixing systems not to exceed $700,000.
