MARYLAND E&S CERTIFICATION 2023 QUESTIONS AND ANSWERS PASSED AND VERIFIED

1. The Erosion and Sediment Control Responsible Personnel Training Pro- gram is a requirement of the EPA State of Maryland International laws None of the above: State of Maryland 2. The current Maryland Standards and Specifications for Soil Erosion and Sediment Control (Handbook) is dated: 1994 2000 2011 2013: 2011 3. Although 2/3's of the earth's surface is covered in water, what percentage is fresh water? 50% 25% 3% 10%: 3% 4. The following is the percent of Maryland residents whose household water comes from a surface water source. 18% 33% 68% 52%: 68% 5. While water is a necessity for human life, clean water also: provides critical wildlife habitat an important part of Maryland's economy enhances recreational opportunities all of the above: all of the above 6. The average Marylander uses how many gallons of water per day? 30 54 77 100: 100 7. Maryland's healthy water resources can benefit the economy by providing water for crop irrigation water for livestock watering electrical power generation good quality fish and shellfish harvests all of the above: all of the above 8. Natural erosion can be caused by water ice wind gravity all of the above: all of the above 9. Raindrops can strike the soil surface at a velocity of 25-30 feet per second. true false: true 10. Sediment pollution is harmful because it: silts in streams, lakes, ponds, rivers, and the Chesapeake Bay increases turbidity in water which can kill submerged aquatic vegetation threatens public safety and may increase flooding carries over abundant nutrients into waterways all of the above: all of the above 11. Sediment runoff to a waterway can result in eutrophication due to higher fish populations which deplete the oxygen turbid water which allows for more plant growth improved condition for spawning excessive algae growth as a result of increased level of nutrients which enter water bodies attached to soil particles causing depletion of oxygen: excessive algae growth as a result of increased level of nutrients which enter water bodies attached to soil particles causing depletion of oxygen 12. The purpose of requiring erosion and sediment control is to: cause undue hardship and expense on the developer and contractor provide jobs for government employees give incentives to contractors by increasing cost of land development provide a means for land development while protecting the environment: pro- vide a means for land development while protecting the environment 13. Land development often accelerates the erosion process because Construction can cause soils to become compacted, inhibiting the absorption of rainfall Drainage areas are often enlarged during construction, leading to increased runoff velocities Vegetation, which helps to diffuse the force of raindrops is removed all of the above: all of the above
