More
and more of our groundwater is being polluted
Between 1960 and 2000,
the scale of groundwater pollution doubled. By 2000, over 280 billion tons of
groundwater was being polluted annually (the same as 280 square kilometers or
9000 tons a second).
Our groundwater is being
polluted with various pesticides and chemicals. In an average US city, tap
water contains over 500 different chemicals.
How
groundwater pollution affects humans
An example of a chemical
often present in drinking water is bisphenol A (or BPA).
Almost a third of
groundwater sites in the US contain BPA. BPA is harmful at very low
concentrations as it interferes with our hormone and reproductive systems. Low
doses of BPA have been found to disturb the cognitive development of infants.
“Tiny
doses of bisphenol A (...) have been found to alter brain structure,
neurochemistry, behavior, reproduction and immune response”. Peter Waldman, The Wall Street Journal,
2005
The
consumer society runs on freshwater
Pollution of Earth’s
groundwater affects humans immensely as modern societies require enormous
amounts of water.
Global use of freshwater
is estimated to be a massive 4.3 trillion cubic meters annually. That’s 530
tons per person a year or 1500 liters daily. Most of the water is used in
agriculture (70 %) and industry (20 %) with households responsible for the
remaining 10 %.
To illustrate how the
water is used for our food and products, it takes 24,000 liters of water to
produce 1 kilo of chocolate; 21,000 liters to produce one kilo of coffee beans,
12,100 liters to produce a smartphone, 15,500 liter for 1 kilo of beef, and
2,500 liters for a cotton t-shirt.
When our groundwater is
polluted, we are therefore polluting many aspects of our everyday lives.
Dirty
water kills
Unclean
water and sanitation are responsible for more lives over the past century than
any other cause. Dirty water causes the death of a human being every 10 seconds
and 850 million people don’t have access to clean drinking water.
Is Your Water Clean?
Humans have established
communities and flourished around sources of clean, drinkable water since the
beginning of time. It’s vital to our survival.
Do you know that you can
survive several days without food but not without water? It’s heartbreaking to
know that millions of people worldwide do not have access to this most basic
need, and are dying of thirst and water borne diseases.
Freshwater sources
around the world are threatened by water pollution. Not only are we managing
our resources poorly through wastage, we are also thoughtlessly dirtying it.
Sources of Pollution
The main sources of
water pollution are the following:
·
Discharge of untreated Raw
Sewage from households and factories
·
Chemicals dumped from Factories
·
Agricultural run-offs that make
their way into our rivers and streams and groundwater sources
·
Urbanization
·
The rising use of synthetic
organic substances
·
Oil Spills
·
Acid Rain caused by the burning
of Fossil Fuels
·
Human littering in rivers,
oceans, lakes and other bodies of water. Harmful litter includes plastics,
aluminum, glass and Styrofoam.
Almost everything that
is a byproduct of our civilization is polluting our drinking water.
Governments, through various Clean Water Acts and water resource policies have
sought to regulate the discharges of pollutants in the water to minimize
pollution and contamination. From 1990 to 2006, an additional 1.6 billion
people had access to safe drinking water. But we are not acting fast enough and
most factories still find a way to dump their toxic wastes in the sea, unseen.
Effect of Polluted Water on Humans
How does water pollution
affect humans? Try drinking untreated water nowadays and your body will
immediately react to it. You will get a stomach ache at the least. Water-borne
diseases account for the deaths of 3,575,000 people a year! That’s equivalent
to a jumbo jet crashing every hour, and the majority of these are
children.
Infectious diseases can
be spread through contaminated water. Some of these water-borne diseases
are Typhoid, Cholera,
Paratyphoid Fever, Dysentery, Jaundice, Amoebiasis and Malaria.
Chemicals in
the water also have negative effects on our health.
Pesticides – can
damage the nervous system and cause cancer because of the carbonates and
organophosphates that they contain. Chlorides can cause reproductive and
endocrinal damage.
Nitrates – are
especially dangerous to babies that drink formula milk. It restricts the amount
of oxygen in the brain and cause the “blue baby” syndrome.
Lead – can
accumulate in the body and damage the central nervous system.
Arsenic – causes
liver damage, skin cancer and vascular diseases
Flourides - in
excessive amounts can make your teeth yellow and cause damage to the spinal
cord.
Petrochemicals – even
with very low exposure, can cause cancer.
These are just to name a
few.
Let’s do our part…
Water pollution is a
known threat to humans and we can do our part to help keep our waters clean.
·
Don’t throw litter in the
ocean.
·
Don’t dispose of chemicals,
paint, in water supplies and drains.
·
If you see anyone throwing
litter into any body of water, report it to the authorities.
·
Help increase awareness by
educating your children and increasing awareness within your community.
