The United States Navy in Guam has been cited by the US Environmental Protection Agency or EPA for several violations of the federal Clean Water Act.
The citations were issued due to lack of certain permits for construction sites, unpermitted discharges into the island's waters and a lack of storm water controls.
The Pacific Daily News reports that the EPA issued the citations following an inspection of the Navy facilities and three naval construction sites.
The US Navy said the violations have no impact to the island's drinking water.
The EPA found that the US Navy failed to fully or properly implement controls for storm water discharges from industrial activities on the base.
It also found that the Navy did not provide sufficient storm water pollution measures at three Navy construction sites.
The EPA also says released water from the Navy's Apra Harbor Wastewater Treatment Plant has exceeded water quality permit limits.
And the agency says the Navy improperly discharged water into the Namo River during repair of its Fena Water Treatment Plant.
Navy officials said they are working with federal and local authorities to address the violations.
