surface water source.
18%
33%
68%
52% - ANS-68%
While water is a necessity for human life, clean water also:
provides critical wildlife habitat
is an important part of Maryland's economy
enhances recreational opportunities
all of the above - ANS-All of the above
The average Marylander uses how many gallons of water per day?
,30
54
77

Maryland's healthy water resources can benefit the economy by providing

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 - ANS-all of the above
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 - ANS-excessive algae growth as a result
of increased level of nutrients which enter water bodies attached to soil particles causing
depletion of oxygen
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 - ANS-provide a means
for land development while protecting the environment
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
