Residents are worried after a pair of sinkholes opened earlier this week in their mobile home park.

On Monday, the first sinkhole swallowed a car in a driveway on 1728 Torch Drive at the Holiday Travel Park. The sinkhole was about 10 feet wide by 10 feet deep.

The second one was found Tuesday, a short distance away from the first one. The second one is about the same size as the first one.

Now geologists say a third soft spot could become a sinkhole at any time.

"Where’s it going to open next? I’m not going back in there," said Laura Meldrum, who has been evacuated from  her home for two days. "I’m just hoping and praying that ours doesn’t go down in a hole."

After the first sinkhole appeared Monday, residents didn't express a lot of immediate concern. Now, most people who live close to the sinkholes have their bags packed and are ready to evacuate at a moment's notice.

"I take medication that keeps me alive," resident Ken Leuthold said. "... They're hard to replace, so we've got those ready, and our important papers, personal effects. You can't pack everything, but we do have things saved. I can grab these three bags and be gone within five minutes, and I can survive."

Six families that evacuated on Monday are still out of their homes. So far, no additional evacuations have been recommended, but that could change, depending on what happens with the sinkholes.

Crews with Pasco County Utilities were working on a sewer lift station on nearby Bartelt Road, but on Tuesday, officials said they were temporarily suspending work while geologists determine what is causing the sinkholes in the area.

“Maybe the stop of the construction was helpful,”said Larry Pickering, the manager of the mobile home park.

“We want to do things certainly safe," said Assistant County Administrator for Utilities Bruce Kennedy. "It is not our intention to create problems like this, I don’t know that we’ve created a problem.”

Testing by geologists on Monday showed several spots of settling in the area, and all of them are being watched closely. More testing will happen later Wednesday as the county and experts work to stabilize the ground before more of it sinks.

Geologists say the land occupied by Holiday Travel Park used to be a swamp or a wetland before it was cleared out in the 1940s. Those areas are known for sinkhole activity because of voids that were not filled in properly.

A contractor working on the sewer lift station just off the property said that since his crew started digging last week, they have found a lot of organics buried in the ground, including big trees, roots and other vegetation.  It remains to be seen if that is a contributing factor to the sinkholes.

“I don’t want to go back into my home until I know it’s safe," said Meldrum. "I also am a little leery as to who do I trust to say that they really know that it’s safe.”
