2023/24 MARYLAND E&S CERTIFICATION QUESTIONS AND
ANSWERS 100% CORRECT
CORE DOMAINS
Water Resources and the Hydrologic Cycle
Erosion Processes and Soil Mechanics
Sediment Pollution and Environmental Impact
Maryland Erosion and Sediment Control Regulations
Plan Review, Inspection, and Compliance
Best Management Practices (BMPs) and Structural Controls
Chesapeake Bay Watershed Protection
INTRODUCTION
This comprehensive examination assesses the erosion and sediment
control knowledge required for Maryland E&S certification. It evaluates
understanding of water resources, erosion processes, sediment pollution,
Maryland regulatory requirements, inspection procedures, and best
management practices. The examination employs multiple-choice
questions with detailed rationales. Emphasis is placed on regulatory
compliance, environmental protection, and the application of erosion and
sediment control principles in real-world construction and land development
scenarios. This assessment prepares candidates for the Maryland E&S
certification examination and professional practice.
SECTION ONE: WATER RESOURCES AND THE HYDROLOGIC CYCLE
1. Although 2/3's of the earth's surface is covered in water, what
percentage is fresh water?
A. 50%
B. 25%
C. 3%
D. 10%
C. 3%
RATIONALE: Only about 3% of the earth's water is fresh water. The
, vast majority is salt water in the oceans. This limited fresh water supply
makes protecting water quality essential.
2. What percentage of Maryland residents' household water comes
from a surface water source?
A. 18%
B. 33%
C. 68%
D. 52%
C. 68%
RATIONALE: Approximately 68% of Maryland residents rely on surface
water sources (rivers, lakes, reservoirs) for their household water. The
remaining 32% use groundwater wells.
3. The average Marylander uses how many gallons of water per day?
A. 30 gallons
B. 54 gallons
C. 77 gallons
D. 100 gallons
D. 100 gallons
RATIONALE: The average Marylander uses approximately 100 gallons
of water per day for household activities including drinking, cooking,
bathing, laundry, and lawn watering.
4. Clean water provides which of the following benefits?
A. Critical wildlife habitat
B. An important part of Maryland's economy
C. Enhanced recreational opportunities
D. All of the above
D. All of the above
RATIONALE: Clean water provides critical wildlife habitat, supports
Maryland's economy (fishing, tourism, agriculture), and enhances
