Board of Water Supply detects petroleum contamination in Moanalua monitoring well

The Honolulu Board of Water supply says it has detected petroleum-related chemicals in a monitoring well in Moanalua Valley, elevating concerns that fuel contamination from the Navy’s Red Hill fuel facility is traveling through the aquifer and putting a major source of drinking water for southern Oahu at risk. The findings also raise concerns that contaminants could be migrating in an unanticipated direction, increasing the urgency of doing more groundwater flow studies.
