Objective To investigate the status of iron and manganese pollution of drinking water in Deyang City, and provide scientific evidence for improving water quality and protecting the safety of drinking water. Methods From 2007 to 2010, the treated water quality in Deyang urban and rural drinking water monitoring sites was continiously tested, with the index changes of iron and manganese observed, and the covered people of the sites investigated. Results During both dry and wet water periods in 2010, the iron content of the water from 3 moni- toring sites （4 water samples） exceeded standard, covered more than 3 000 people, with a pass rate of 99.20% for iron content; while the manganese content of the water from 10 monitoring sites （16 water samples） exceeded standard, covered more than 1 500 people, with a pass rate of 96.81% for manganese content. Conclusion During 2007 -2010, the passing rate of iron and manganese content in treated water from Deyang urban and rural drinking water monitoring sites rised continiously.
