A massive oil spill in the Baltimore Harbor that began Wednesday has now dumped 5,000 gallons of diesel fuel into the harbor, more than doubling the amount initially reported.

Many of the large pools of diesel fuel, noticeable by its distinct red color from dye, have been removed from Baltimore's harbor two days after a 2,000-gallon spill.

Officials said the water is red because there is dye in the fuel, but there is no impact to the area’s drinking water.
