Environmental Protection Agency officials may take control of some mismanaged U.S. Virgin Islands environmental programs that allowed issues such as bacteria-infected drinking water, a government watchdog reported.

The U.S. territory for years has neglected duties required by its millions of dollars in grants, such as monitoring water and air quality and enforcing regulations, according to the Environmental Protection Agency inspector general. The agency awarded $4.6 million to carry out such duties through 2014.
