In the context of climate change and water security risks globally, we are taking steps to assess our potential future water management risks and monitor current water management performance. Currently, the availability and quality of supply water to our operations is not considered a significant risk because all our sites are located within the U.S. (including Puerto Rico) and Western Canada. We annually invest capital to improve our overall water management and conservation capabilities.
As air quality emissions controls evolve, our water usage requirements may increase, making ongoing efficiency improvements even more important. Our water strategy focuses on maximizing direct use of recycled water, reducing reliance on freshwater, and decreasing the overall amount of water we use. Recent enhancements include a new cooling-water system for our electric arc furnace, which represents 58 percent of our total water withdrawal but has an 80 percent water re-use rate.
