| Higgins
and Associates has a wide range of experience in conducting
assessment activities. This experience ranges from facility walk
through and record reviews to meet the requirements of a Phase I
assessment, to developing and conducting complex multi-stage assessments
to define chlorinated hydrocarbons. Some of the types of intrusive
assessment technologies which Higgins and Associates utilizes are
as follows:
| • |
Geoprobe/push probe
drilling methods |
| • |
Drilling of soil borings and/or
installation of monitoring wells utilizing hollow stem auger,
mud rotary, or air rotary methods |
| • |
Soil gas surveys |
| • |
Geophysical surveys including ground
penetrating radar and magnetic surveys |
| • |
Utilization of Air Knife for assessment
of impacts along utility corridors |
Higgins
and Associates experience with the application of the above
technologies in various lithologies allows us to apply the appropriate
technology for site conditions resulting in improved assessment
data.
