GWA: ELEVATED DIELDRIN LEVELS LIMITED TO WELL Y-15 (MANGILAO, GU) —Guam Waterworks Authority (GWA) confirms well Y-15 located in Yigo is the only GWA well operating with elevated dieldrin levels, according to General Manager Miguel C. Bordallo. “Previous reports from various government and media outlets have reported two operating wells with elevated dieldrin levels, which is an error,” said Bordallo. “All other wells operating in the Northern and Central water systems, and water sources for the Southern water system are not impacted by well Y-15 and are providing water which remains below the Guam EPA Interim Action Level for dieldrin and in compliance with drinking water regulations.” GWA is working closely with the Yigo Mayor’s office to provide cooking and drinking water to affected customers, and continues to monitor the entire water distribution system to ensure safe drinking water is distributed island wide.
