The ISCO automatic samplers have finally arrived along with
the flow monitoring equipment. The flow
and sample monitoring will be observed remotely at our office in Stillwater through
the purchasing of a Verizon data plan.
Basically, we will be able to monitor what the samplers are
doing/measuring at any time. This way,
when there is a flow event, we will know it immediately and obviously know to
go to the site to collect the sample bottles as soon as possible for laboratory
analysis.
We recently poured some concrete at the inflow side of the
structure. The picture below shows the “before”
picture and you can see that the inflow pipes (black) are at varying elevation
from the surface, which is bare soil. We
wanted to create a clean and level “apron” where the inflow runoff water can
enter the structure. Eventually, there
will be perforated plastic pipe attached to the other side (inside the
structure) of the black metal pipe. This
pipe will be buried in the slag and will serve to evenly distribute the
inflowing water (i.e. serve as a manifold).
The next pictures show the concrete work:
Also on this site visit we can to lay the pipe which will hold the suction lines for the automatic samplers and the bubbler tube for the flow monitor.
Not very exciting.
However next week we will sieve the slag and put it in the structure and
finish up the installation of the monitoring equipment.
I would like to briefly highlight the work by Dr. Stefan Jansen in The Netherlands, here.
