The filters may also be selected to absorb oils salts or other chemicals. The temporary barrier is easy to install and remove. The barrier plates and filters fit to the size of the culvert mouth and have adjustment slots for different width mouths. The culvert barrier may be used to prevent pollution at construction sites and be temporarily or permanently attached to culvert mouths. The filters may be changed or cleaned as required.
