This document discusses various environmental sciences relevant to studying water quality and groundwater flow, including geology, hydrogeology, soil chemistry, toxicology, and biochemistry. It notes that hydrogeology, which involves studying the distribution and movement of groundwater, was a main focus in the book. The document expresses particular interest in hydrogeology and appreciation that computers now allow complex modeling of groundwater flow with calculations.

1. Environmental Sciences
Geology- the study of the Earth
Hydrogeology- the distribution and movement in groundwater in the Earth (this is a main focus
for the water quality of the wells and the chemicals flow involved there)
Soil chemistry- the study of the chemical characteristics in the soil
Darcy’s law- an equation that shows the flow of a liquid through a porous medium (used by
Nesson)
Toxicology- studies the effects of chemicals on living organisms
Biochemistry- the study of chemical processes within or revolving around a living organism
Epidemiology (although is a medical science)- deals with the distribution/control of diseases
(this could consider the cancer clusters)
These sciences along with some of the other more medical ones, help the plaintiff make a
case in the book. However, I find all these topics to be very interesting especially hydrogeology.
There is just so much areas on Earth that can be studied and discussed, people tend to forget all
the forms of water. That is why that seems to be an area people should try to focus more on.
However, there was a lot of work done on the groundwater flow in the book, and that is a good
start and it amazes me how we can now track this movement on a computer with a few
calculations.
