Subjects Geology

Objectives Develop a standard site characterisation methodology.

  Statistical analysis of sand lens distribution and practical approaches.

  Investigations at several sites to see if the method is working.

Activities Excavation to 5 m

Observations of gravel pits

Drilling

Core samples, terrain to regional aquifer (GeoProbe/Bore Rig)

Subjects Hydrogeology

Objectives Characterisation of effective transport properties of fractured sites.

Activities Piezometric investigation

Slug tests

Pump tests

Permeability

Groundwater model

Water balance

Tracertests?

Detailed hydraulic conductivity (Waterloo profiler)

Subjects Contamination, Processes, Bacteria

Objectives Detailed description of contaminant, organic and bacterial distribution in groundwater and matrix.

  Understanding of all the complex processes and where these takes place.

Investigate which microorganisms that are present, as well as their ability to move from permeable layers into the clayey till matrix.

Activities Drilling Soil sampling, analysis Water sampling, analysis Fatty Acids Core samples, terrain to regional aquifer

(GeoProbe/Bore Rig) MIP Thin sectioning Viable microorganisms (both unsat and sat) DNA (TCE, TCA) RNA, DGGE profiles
