St. Louis, MO (KSDK)- It has been an uneasy Easter Sunday for those living near a steam pipe break in downtown St. Louis.
Cleanup crews are finishing their work but, 11th and Convention Streets are still closed until test results are in.
A plume of steam towered over 11th Street near Lucas Avenue on Thursday shutting down the street after a pipe burst.
"It kind of freaked me out," said Celia Montes, a resident at the Lucas Lofts.
Workers have been right outside her door since Thursday morning.
"It made me a little bit nervous considering the fact that people are cleaning up and they have the hazmat masks on and we're free to come in and out," said Montes.
The workers are wearing masks because after they fixed the leak, swab samples found small amounts of ground level asbestos.
"They told us not to open our windows and they told us not to be in the balconies so that led me to believe it wasn't really a safe area," said Montes.
"Apparently asbestos causes cancer but, hopefully I am OK. Hopefully I haven't inhaled too much air around here," said Nathan Ziebold, a resident at Lucas Lofts.
Health officials say so far initial air quality tests have come back clean.
Crews worked for three days straight, including through the holiday, to make sure the area gets cleaned up and is safe as fast as possible.
"They are here on Easter and they have families as well so they are making a good sacrifice to try to make any hazardous materials out where the general public can be hurt by them so good for them and I am saying thank you," said Ziebold.
Crews are still investigating how the pipe broke.
"I am hoping I don't get sick and I am hoping it's just over with," said Montes.
The asbestos samples taken on Sunday will be analyzed on Monday. If the samples come back positive crews will be back in the area cleaning again.
