What exactly is meant by saying the borings will be continously logged? It that the same or different from being <br /> continuously cored? <br /> 2. Am I understanding correctly that there will be no soil samples for analysis collected from the borings? <br /> 3. Will the water samples from the borings definitely be collected by Simulprobe, or are you also considering another <br /> method? If so, what is it? <br /> 4. Why are you proposing to collect discrete samples at 75-feet bsg? Two of the wells onsite are screened at this depth <br /> and the water is contaminated. Shouldn't we start deeper? <br /> 5. Since you are proposing to use hollow-stem for the borings, wouldn't it be more cost effective to use them to construct <br /> deeper wells? There is documented groundwater contamination to 75-feet bsg already, deeper wells must be installed. It <br /> just kind of seems like a waste to me to fill the borings with cement and then drill more. <br /> Thats what I have so far. I will try calling again on 12/11/00. Lori Duncan <br /> 1 <br />
