Hydrogeologist

A hydrogeologist is a person who studies the ways that groundwater (hydro) moves through the soil and rock of the earth (geology). A similar profession, a hydrologist, is someone who studies surface water. Hydrogeologists also oversee the cleanup of spills and contamination. Contaminants in groundwater move through soil and rock, sometimes causing people to become sick far from the source of contamination. Groundwater contaminants can come from: Here's what they might do on an average day:
 * natural mineral or chemical reactions in the earth
 * air pollution (contaminants carried down into the soil or rock by rain soaking into the ground)
 * insects and animals that get trapped in wells
 * people's actions at home or businesses practices
 * human and animal waste
 * dumping or spilling harmful substances on the ground
 * investigate ways to test water to be sure it is safe to drink
 * check licenses of people who construct wells and supply water to others
 * inspect and/or help locate wells for safe water supplies
 * inspect the design and function of wells
 * help people understand the interactions between soil and other geologic formations and groundwater
 * study groundwater flow in different parts of the state
 * write new laws to protect groundwater
 * train others to protect groundwater
