SUBJECT: AIR SAMPLING/ CHANGE IN MOB DATE FOR S&ME
As you are aware, we began pulling air samples yesterday at the landfill. Due to the
heavy medium we are collecting in, we are only able to get about 1 liter per minute or less
through the pumps. Due to the limitations on the pumps and the necessary re-charge time, we
will need the rest of the week to complete the 1500 liters required.
I just got off of the phone with S&ME and asked that they mobilize on Friday, and begin
work on Monday in order to allow us sufficient time to complete the sampling prior to their
breaching the liner.
We have also had some rain this week which has slowed our progress as well.
I have completed a work schedule for DWM folks to be at the landfill for the next few
weeks, using a mix of engineers, hydro's and geologists.
Remember, we have the bench scale pre-bid meeting on Monday, here at 10:00 am. I
have not heard much response from companies (actually, only 4, and one was a notice to "no bid"
this RFP. I hope some companies show up!!!
