Question 1

What is the purpose of a Preliminary Hazardous Materials Survey (also called a Phase I ESA) when evaluating a site?

Accepted Answer

To identify potential environmental contamination without invasive sampling

Answer

A Phase I Environmental Site Assessment reviews historical records, regulatory databases, and site conditions to identify recognized environmental conditions without physical sampling.

Question 2

In wastewater treatment, what is the function of the secondary treatment stage?

Accepted Answer

Remove dissolved and suspended biological matter through biological processes

Answer

Secondary treatment uses biological processes, such as activated sludge or trickling filters, to remove dissolved organic matter and suspended biological solids after primary settling.

Question 3

Which engineering principle describes designing infrastructure that can handle peak flows while preserving natural hydrology?

Accepted Answer

Low Impact Development (LID)

Answer

LID is a stormwater management approach that mimics natural hydrologic processes through techniques such as bioretention, permeable pavement, and green roofs.

Question 4

What does the term 'remediation' mean in the context of environmental engineering?

Accepted Answer

The process of cleaning up contaminated soil or groundwater

Answer

Remediation refers to the removal or neutralization of contaminants from soil, sediment, or groundwater to restore an environment to acceptable conditions.

Question 5

Under the Clean Air Act, what is a 'criteria pollutant'?

Accepted Answer

A common air pollutant for which the EPA has set National Ambient Air Quality Standards

Answer

The EPA identifies six criteria pollutants (e.g., ozone, PM2.5, CO, NO2, SO2, Pb) for which it sets NAAQS to protect public health and the environment.
