What is the project about?
What do you need information on?
What are you required to have?

What types of studies come under site investigation?
Who does these?
What are pertinent laws?

What are the phases of a site investigation?

Hydrogeology
Water table, Unconfined, confined aquifer, K
How do you map water tables?

Why is the geologic setting so important? Why do you need a conceptual model?
What are some of the variables which influence groundwater flow?
What is the vadose zone?
Why do you need to know the chemistry of the pollutant?

Topos are produced by the USGS
They can be ordered from the USGS, usually the state survey, often commercial dealers, for instance from MAPSCO in Texas (Camp Bowie). They are available in digital form on-line through various GIS distribution points.
Most topo maps are $6
