As a county health department employee in Arizona, you have decided to test water samples taken from households in your county for levels of arsenic. You want to compare the arsenic findings with previous cancer diagnoses of members of the community of Zona. The water samples were recently collected by the state department of environmental quality, and you will conduct surveys on the individuals in each household for overall health history and recent dietary intake.
