Ambassadors for a Clean Bay
-
The 1972 amendments to the Federal Water
Pollution Control Act (known as the Clean Water Act or CWA)
specifically required EPA to develop and implement the National
Pollutant Discharge Elimination System (NPDES) program.

ARTICLE XI of Virginia's Constitution
Conservation
Section 1. Natural resources and historical sites of the
Commonwealth.
To the end that the people have clean air, pure water,
and the use and enjoyment for recreation of adequate public lands,
waters, and other natural resources, it shall be the policy of the
Commonwealth to conserve, develop, and utilize its natural
resources, its public lands, and its historical sites and buildings.
Further, it shall be the Commonwealth's policy to
protect its atmosphere, lands, and waters from pollution,
impairment, or destruction, for the benefit, enjoyment, and general
welfare of the people of the Commonwealth.
It is your Constitution Right to
have CLEAN WATER!!
In 1972 there were over 8,000 working watermen in
Virginia. Although 3,000 Virginian's hold a Commercial Registration Card
today less than half could be classified as full time working watermen.
What has happened? Is it overharvesting as many would have you believe
or has pollution caused the decline in the once plentiful bounty that
the Chesapeake Bay provided?
Virginia's Watermen Say it is Pollution!!!
-
Nitrogen and phosphorus run off cause algae
blooms that prohibit sunlight from getting to grass beds (submerged
aquatic grasses)
-
Bay grasses serve as protective nurseries for
young crabs and fish, including menhaden, herring, shad, spot,
croaker, weakfish and white perch. Bay scientists have found 30
times more juvenile blue crabs in bay grass beds than in areas with
no grasses.
-
Just like humans the animals in the Bay need
oxygen. High amounts of nutrients in the water, called nutrient
pollution, can fuel the growth of excessive algae, or algae blooms.
A portion of the algae is consumed by filter feeders like oysters.
But unconsumed or “leftover” algae die and sink to the bottom of the
Bay, where they are decomposed by bacteria. During this process,
bacteria consume oxygen until there is little or no oxygen left in
these bottom waters causing dead zones. Animals in these zones
DIE!!!
-
Sediments are a natural part of the
Chesapeake Bay, created by the weathering of rocks and soil.
However, in excess, sediment clouds the waters of the Bay and its
tributaries, which harms fish, oysters and underwater bay grasses.
Oysters and other bottom-dwelling species can be smothered when
excess sediment settles to the bottom,
excess sediment is the
primary reason that many of the Bay watershed's streams are
degraded, ports and channels can become clogged by accumulated
sediment, affecting commercial shipping and recreational boating.
