The incident is not a public health threat, officials say, but residents experiencing severe illness were told to call 911.
There was a hazardous material issue at the gas station, and the odor of gasoline drifted into the neighborhoods through which the wash flows. Those neighborhoods include: Pasadena, South Pass, San Marino and Alhambra.
The duration of this incident was initially expected to last about 6 hours. The spill was cleaned up by Monday morning, nearly 15 hours later, but the smell of gasoline lingered in the air.
The gas station reopened for business around 3 a.m. Monday morning.
