Guam – High levels of iron and manganese in water originating from the Fena Reservoir have caused a brownish tint in the drinking water supplied to Navy housing residents, and Guam Waterworks Authority customers in parts of central and southern Guam.
The water is safe to drink and continues to meet guidelines set forth by the Federal Safe Drinking Water Act.
Iron and manganese are naturally occurring elements that only affect the aesthetic quality of the water.
The Navy has initiated treatment procedures to remove these elements and to return the water to its normal appearance.
Noticeable improvement in water clarity should be apparent within two days, and normal water conditions are anticipated within seven days.
The high levels of iron and manganese were caused by planned maintenance on the system at the Fena Reservoir.
