PE ENVIRONMENTAL ENGINEERING EXAM
QUESTIONS WITH CORRECT ANSWERS
Grab Sample - Correct Answers -Oil and grease, during a wastewater 24 hour
composite sampling event, are taken as a grab sample because of the difficulty and
collecting composite oil and grease samples.
composite sample - Correct Answers -Composite samples are made up of a number of
of individual grab samples over an extended period of time, usually 24 hours
How do you tell what micro biological contaminant is most resistant to chlorine
disinfection? - Correct Answers -A higher chlorine contact time (CT) is lower
effectiveness. (Most resistant).
Noise reduction coefficient - Correct Answers -Relates to sound absorption by features
and furnishing within a space.
Noise reduction rating - Correct Answers -Relates to hearing protection devices
Transmission loss - Correct Answers -Amount of sound energy loss when sound passes
through a barrier, such as acoustic pipe insulation.
Bioaerosol sampling methods are not applicable to measuring compliance with the TLV
for total, cultural organisms and particles because - Correct Answers -Cultural
organisms or countable spores do not compromise a single entity,
human responses to buy aerosol range from innocuous effects to serious disease and
depend on the specific agent and susceptibility of the person
measured concentrations are dependent on the method of sample collection and
analysis.
Chemiluminescence - Correct Answers -the generally accepted technique for measuring
attainment with the national ambient air quality standard for NOx.
Ways to control NOx formation for internal combustion engines - Correct Answers -
Positive crank case ventilation system,
three-way catalytic converter
, exhaust gas recirculation system
valve timing
Absorption and retention of organic chemical pollutants by soil is strongly affected by -
Correct Answers -Soil organic content
A characteristic hazardous waste can only be rendered non hazardous by... - Correct
Answers -Removing the contaminant concentration below the regulatory level
What compound is a chemical component of the smoke tubes used in ventilation
studies? - Correct Answers -Titanium tetrachloride
What organic components are typically found in municipal solid waste? - Correct
Answers -Carbon, hydrogen, oxygen, nitrogen, sulfur, and ash.
Geophysical methods used to sense hazardous waste underground - Correct Answers -
Metal detection, ground-penetrating radar, and resistivity.
SW - 846 - Correct Answers -Document titled "test methods for evaluating solid waste:
physical and chemical methods"
This publication of the EPA sets forth acceptable methods for sampling and analysis in
compliance with RCRA.
Clean Air Act (CAA) 1970 - Correct Answers -Title I: provisions for attainment and
maintenance of national ambient air quality standards
Title II: provisions relating to mobile sources
Title III: Air toxics
Title IV: acid deposition control
Title V: permits
Title VI: stratospheric ozone and global climate protection
Title VII: provisions relating to enforcement
The dose response relationship for a carcinogen is - Correct Answers -Linear with no
threshold dose
Insertion loss - Correct Answers -Best predictor of the perceived sound reduction.
Insertion loss is the difference in sound pressure levels before and after insulation is
applied.
