Before you watch the video understand this System is a visable partically above ground dry well retention.
The sand acts as a filter to catch the oil.
True or False
If this was not built here would the oil have a better chance to Polute the earth?
True the retention area is working and stopping oil.
False this retention has nothing to do with catching oil and it serves no purpose.
I took this video two years ago after I read that Maryland is high on compliance for Clean Water Act built properties
