MECKLENBURG COUNTY, N.C. — If you need to fill up your gas tank before Thanksgiving, be careful where you stop.
Channel 9 found dozens of stations in Mecklenburg County that are accused of selling tainted gas.
It's an issue we've followed all year, and we just learned the problem is only getting worse.

Inspectors condemned 70 pumps at dozens of gas stations in Charlotte this year -- a 30 percent increase from last year, when they condemned 53 pumps.
Driver Benedict Vani fueled up at a pump condemned in June for water in the fuel.
"I think it needs to be regulated, needs to make sure what we're putting in our fuel tank is what we're buying," Vani said.
Valerie Jackson told Channel 9 she is traveling to Atlanta for the holidays.
"I'm fueling up to head out on a trip and hopefully my car will work fine," she said.
