NCEES Environmental Engineering 2

Question 1

For the NCEES PE Environmental exam, the Clean Air Act (CAA) National Ambient Air Quality Standards (NAAQS) regulate:

Accepted Answer

Six criteria pollutants including PM2.5, ozone, CO, NOx, SO₂, and lead

Answer

NAAQS establish primary and secondary standards for six criteria pollutants: PM2.5, PM10, ozone, CO, NO₂, SO₂, and lead.

Question 2

In NCEES PE Environmental practice, the solid waste landfill liner system's primary function is to:

Accepted Answer

Prevent leachate migration into groundwater

Answer

Liner systems (clay + geomembrane) prevent leachate from contaminating underlying soil and groundwater.

Question 3

On the NCEES PE Environmental exam, Darcy's Law for groundwater flow states that flow rate Q equals:

Accepted Answer

Q = KiA (hydraulic conductivity times hydraulic gradient times area)

Answer

Darcy's Law: Q = KiA, where K is hydraulic conductivity, i is the hydraulic gradient, and A is cross-sectional area.

Question 4

In NCEES PE Environmental engineering, the log-removal credit for Cryptosporidium in drinking water treatment is governed by:

Accepted Answer

EPA Long Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR)

Answer

The LT2ESWTR requires utilities to provide additional treatment for Cryptosporidium based on source water monitoring results.

Question 5

For the NCEES PE Environmental exam, the bioconcentration factor (BCF) for a contaminant in fish describes:

Accepted Answer

The ratio of contaminant concentration in the organism to that in water

Answer

BCF = Corganism/Cwater: a high BCF indicates a pollutant accumulates in organisms relative to its concentration in water.
