High levels of mercury have been detected in a sink at Pearl Harbor Kai Elementary School.
The Navy says samples showed mercury at nearly twice the acceptable level set by the U.S. Environmental Protection Agency.
The sample was taken on March 16 and is part of the water monitoring and testing protocol instituted by the Navy in the wake of jet fuel contamination of its water distribution system at Pearl Harbor.
Officials say the mercury was found in an indoor sink at the school that is not used by students.
They say the faucet is the source of the mercury, not the water itself.
The Navy and state Department of Health had the faucet replaced, and are in the process of flushing the pipes and resampling the water.
