Preview Questions Water Resources Engineer | Role Specific Skill

Question 1: In water quality monitoring, which of the following parameters is a direct measure of the potential for oxygen depletion in a water body?

Which action should you take?

Choose only one option

Total suspended solids (TSS)

Chemical oxygen demand (COD)

Nitrate concentration

pH

Question 2: How do you optimize the performance of a reverse osmosis (RO) membrane system in a water treatment plant?

Which action should you take?

Choose only one option

By running the system at maximum pressure to achieve higher recovery

By reducing feedwater pretreatment to save costs

By adjusting feedwater chemistry, pretreatment, and cleaning protocols to reduce fouling and increase flux rates

By increasing membrane replacement frequency without optimizing fouling control

Question 3: How do changes in land use impact the hydrological response of a watershed?

Which action should you take?

Choose only one option

Agricultural land use has no impact on watershed runoff behavior

Urbanization typically reduces the runoff coefficient, leading to higher discharge

Deforestation can increase infiltration rates and reduce runoff

Urbanization typically increases runoff volume and peak flow rates

Question 4: How does the Clean Water Act's "point source" definition relate to wastewater treatment?

Which action should you take?

Choose only one option

It applies only to agricultural runoff sources

It applies to air pollutants discharged from wastewater treatment plants

It defines wastewater discharges from specific locations as regulated discharges

It refers to the amount of water used in industrial processes

Question 5: How do you determine the presence of heavy metals in wastewater samples and their impact on aquatic ecosystems?

Which action should you take?

Choose only one option

By measuring general metal concentrations and ignoring toxicity

By assuming that all heavy metals behave the same way in water systems

By using colorimetric tests without identifying specific metals

By using atomic absorption spectroscopy (AAS) or inductively coupled plasma (ICP) and analyzing toxicity

Question 6: What is the term used to describe the process of water flowing through a river and eventually into the ocean?

Which action should you take?

Choose only one option

Evapotranspiration

Surface runoff

Baseflow

Streamflow
