About Hydrologic Technicians

Environmental Scientists study the natural environment and identify how human activity affects ecosystems, air quality, water quality, and soil health. They collect environmental samples, conduct field surveys, analyze data, and prepare reports that inform regulatory compliance, remediation planning, environmental permitting, and natural resource management. In consulting, environmental scientists conduct Phase I and Phase II environmental site assessments to identify contamination at properties being acquired or sold. They oversee remediation of contaminated sites, collecting soil and groundwater samples to monitor cleanup progress against regulatory cleanup goals. Wetland scientists identify and delineate wetland boundaries for Clean Water Act permitting and assess impacts of proposed development. Air quality scientists monitor emissions, model pollutant concentrations, and prepare air permit applications. Environmental scientists also work for regulatory agencies, reviewing permit applications, conducting inspections, and enforcing environmental laws. Natural resource agencies employ them to assess habitat quality, manage wildlife populations, and evaluate the ecological impacts of proposed infrastructure projects. A bachelor's degree in environmental science, ecology, geology, or chemistry is the typical entry credential.
