Preview Questions Environmental Engineer | Role Specific Skill

Question 1: What is a key advantage of using electrostatic precipitators (ESP) in industrial air pollution control systems?

Which action should you take?

Choose only one option

They are highly effective at removing gaseous pollutants

They require minimal maintenance

They are low-cost solutions for controlling particulate emissions

They provide high removal efficiency for both fine and coarse particulate matter

Question 2: Under the Safe Drinking Water Act (SDWA), how does an environmental engineer ensure compliance when a chemical plant discharges wastewater into groundwater sources?

Which action should you take?

Choose only one option

Discharge wastewater directly into groundwater without treatment

Conduct regular monitoring of groundwater quality and ensure that the facility's discharges do not exceed contaminant limits set by the EPA

Focus solely on surface water and ignore groundwater

Ignore the potential for contamination

Question 3: Which of the following is a major challenge associated with the use of activated sludge in wastewater treatment in the chemical industry?

Which action should you take?

Choose only one option

Inability to degrade nitrogen compounds

High energy requirements for aeration

Difficulty in maintaining microbial growth

Slow sludge settlement rate

Question 4: In an EIA, what is the purpose of a "No Action" alternative?

Which action should you take?

Choose only one option

To serve as a baseline for comparing other alternatives

To evaluate the environmental risks if no mitigation is implemented

To assess the potential for environmental improvement

To evaluate the economic impact of halting the project
