Pollution of Water|
Water can dissolve so many chemicals
Water can leach out toxic materials
Water can transport pesticides, fungicides
Water takes mud with all its materials
Water can erode creek and river beds
un-earthing sins from the past.
Water pollution is today a big issue, a global threat to all life on Earth!|
On this web page we just try to give you a little glimpse - email us to learn more!
Look at all the different sources of water pollution!
A) sediment from croplands, forestry activities
B) construction sites, river bank erosion
C) fertilizer from croplands, lawn and gardens
D) runoff from livestock operations, septic systems
Which water channel would you prefer? BSB keeps Earth beautiful!!
Sediments from erosion can reduce clarity and sun penetration in bodies of water, harming aquatic plant life and fish.
Nutrients, such as runoff from over-fertilized areas in waterways can cause excess plant and bacteria growth, resulting in eutrophication = oxygen depletion and fish kills.
Bacteria from livestock, seepage from improperly maintained septic systems, leaking sewer lines, wildlife, and urban runoff is all washed into creeks, rivers, oceans by rainfall.
Man-made chemicals, including pesticides from roadways, croplands, lawns, gardens, and forestry operations; toxic materials, such as improperly applied pesticides or automotive products such as motor oil, engine degreaser and antifreeze is washed into creeks, rivers and into the oceans.
The list goes on:
Illegal dumping, surface trash, such as plastic containers or cigarette butts: all these materials and chemicals leached out of them are washed into our water supply, our water bodies.
Look at a patch of plastic trash in the Pacific ocean
Scientists call all that
Nonpoint Source (NPS) Pollution.
Who is responsible?
With all these different sources of pollution|
Where is the problem with water pollution?Healthy aquatic water has a lot of dissolved oxygen (DO). Oxygen is a basic requirement and beneficial for fish, insects, worms. Most fish species suffer if DO concentrations are below 4 mg/L.
Insect larvae and juvenile fish are more sensitive and require even higher concentrations of DO to function in a healthy way.
Oxygen concentrations vary under natural conditions, but severe depletion often is the result of human activities. Large quantities of biodegradable organic materials are dumped on the ground or into surface waters.
What are biodegradable organic materials?
A few examples:
Lawn clippings, raw and treated sewage, food processing wastes, rice field drainage, and pulp paper wastes. They deplete the water of oxygen. As these wastes decompose and break down into essential nutrient enriched building blocks, many chemical and biological processes are directly affected.
Too much nutrients including the fertilizer nitrogen and phosphor over-stimulate the growth of aquatic plants and algae. Excessive growth of these plants, in turn, can clog waterways.
Over fertilized water plants out-compete native submerged aquatic vegetation. When they decompose oxygen depletion is the outcome.
Oxygen concentrations increase during day light when aquatic plants use photosynthesis to produce their food, resulting in a good oxygen production.
Earth got its oxygen from all the different plants, many in our seas and oceans.
Nature on Earth always works best when in balance.
Fertilizers, malfunctioning septic systems, detergents and organic materials in treated sewage, and manure in agricultural runoff are the enemies of balance. Water quality degradation is the outcome.
The outcome of another big problem is shown on the photo below. Millions of plastic trash is washed into our oceans, and the inhabitants of Earth's oceans have to deal with it.
Sea life dies by the ten thousands, killed by humans who do not care!
Or do they just not think about, what their plastic trash can do???
He had no hands to take this piece of plastic of his mouth...
Water is very important for all life!
Look at this mess!
