This crew from URS is testing the side of Brooks Road. The road has been mapped out and they test both sides and the center of the road every 250 feet. They take samples every 500 feet. The person writing down the results has the GPS hand held unit to be sure they are at the right spot.
The results from the samples will be compared with readings on the machine being pressed against the dirt. The cross testing is to insure the machine is getting accurate readings. Then they can test anywhere just by pressing the machine against the dirt. I watched 3 readings while I was talking with the crew. Each one took a little over a minute to do.
Once the machine readings are confirmed by lab results, it will be much faster for them to test, and they can test anywhere they can take this machine. It is about the size of hand held blender.
Earlier I had been out walking and spoke with them, the vacuum crew and one of the drivers of a County grader. They seem to be working the road as a unit.
The road has already been marked with spray paint colored arrows for the vacuum crew. The testing crew seems to be the supervisors. The grader comes along behind and cleans up anything the testing crew finds on this pass up the road.
While I was out for my walk, the County Road Crew had to do some grading because the machine found some lead at one spot.
I have to admit, this is the first time I am beginning to feel comfortable with the clean up efforts.
It seems to be very thorough. And this is just the preliminary work!
