ABSTRACT
This chapter presents six case studies that demonstrate the principles we have studied in this book up to this point. Those principles include:
How do contaminants get into the environment
What happens to contaminants once released into nature
Why certain contaminants cause more harm than others
How does the geologic environment influence contaminants
How much do it cost to clean up the environment
Why certain geologic environments are especially sensitive to contamination
The case studies presented in this chapter highlight the need for either improved environmental regulations or new regulations altogether within the following subject areas that are covered in the final section of this boot:
Banning or restricting the use of certain chemicals (specifically, CVOCs and CR+6)
Improving land-use planning that does not permit or limits use of certain chemical in especially sensitive geologic areas
Improving pollution prevention techniques
Sustainability regulations that incorporate science-based chemical-specific use criteria that includes mobility and persistence into evaluating chemical risk
The need for improved engineering and institutional control
