Seven Lowcountry nonprofit agencies are in the running for part of $2.5 million being given away in the second round of the Chase Community Giving Campaign, which starts Thursday.

The seven groups -- Charleston Animal Society, Coastal Conservation League, Crisis Ministries, Historic Charleston Foundation, Pet Helpers, South Carolina Aquarium and Water Missions International -- beat out thousands of other charities nationwide to receive enough votes in the first round of the Facebook contest to each earn $25,000 as one of the top 100 vote-getting charities.

In the second round, the 25 charities with the most votes will receive between $20,000 and $500,000, based on votes. The winners will be announced May 26.

To launch the contest, representatives from each organization will gather at 12:30 p.m. Thursday at Charleston Visitors Center at 375 Meeting St. to urge metro residents to vote and say how they would spend the money if they win.
