This spring I will be conducting a Phase II project in Dubuque, Ia. Several of the sites we will be investigating are connected with the lead mines from the 1700 and 1800's. I would like to know if anyone has information or references for conducting archaeology in this type of situation. I am primarily concerned with health and safety issues although I would like additional information on techniques and all things archaeological.
