A team of inventors, Michael Hasting and Geoffrey Lindsay from NAWCWPNS/China Lake, and Michael Gustavson from NAVSEA have been awarded the 1996 Vice Admiral Harold G. Bowen Award for Patented Inventions for their work on "Extended-Release Plaque Preventing and Dissolving Compositions," Patent Number 5,328,633. The Navy had a problem with sewer lines being clogged with hard calcium crust and their invention, citric acid tablets, was a better solution then the bags of sulfamic acid that had been used previously in the flush water on every aircraft carrier and ship in the fleet (except a few submarines). Over 1.5 million hockey puck-sized tablets per year are used by the fleet, saving the Navy about $4M annually in hydroblasting costs.
