Ports in South Carolina and Georgia saw a brisk increase in business in August, ports authorities in both states said today.

Shipping container volume, which is the main source of port revenues, increased 19.3 percent at the Port of Charleston and nearly 14 percent at the Port of Savannah last month, compared to August 2011.

Ports in both states also saw sharp increases in non-container cargo, such as bulk products, automobiles and heavy machinery.

In Charleston, August was the strongest month for container volume since October 2008 and the seventh consecutive month of year-over-year gains, the State Ports Authority said. Container volume in Charleston remains well below pre-recession highs.

In Savannah, which moves roughly twice as many containers as Charleston, August marked the second-highest container volume ever recorded at the port.
