Construction Entrance Fail

Another construction entrance fail. Vehicles drive through the Soaker tire wash, over some rock, then over dirt and sand, defeating the purpose of the tire wash. This exit from the tire wash needs to be rock or asphalt to the street. Disclaimer: I do not promote any products or suppliers.

Construction Erosion Inspection-Turbid Discharge

6000 NTUs Photo: David Jenkins

A little bit of sediment track out each day builds up. The contractor was vacuum sweeping this area on a regular basis but the first rain shows how effective that was. I measured this discharge at 6000 nephelometric turbidity units (NTUs) using an old Hach 2100P turbidimeter. This meter only reads up to 1000 NTUs, so I had to dilute the sample 3 times to determine the actual reading.

Sediment Track out-I’ve had Enough

Another day, another random drive by construction erosion inspection. This is an ongoing issue and remains unresolved.  I issued a Non-Conformance Report stating that the construction entrance/exit will remain closed permanently unless a solution is found and implemented.

Funny thing, when wet, the stuff is like quick sand. When dry and compacted to 95%, it is hard as a rock and will not infiltrate water.

Construction Erosion Inspection-Site Looks Bad but No Dirty Discharge

It looks like a dirty, poorly managed site on first inspection, but is it really? When you get the whole story this project turns out have a low risk for water quality compliance violations.
