Critical Facts about Water-Borne Diseases

by admin

15 May

If you live in a developed country, and I assume many of you are if you’re reading this, waterborne diseases probably aren’t something you typically worry about. But did you know that poor water sanitation and a lack of safe drinking water take a greater human toll than war, terrorism and weapons of mass destruction combined?

Even in America, pumps, pipes and purification facilities could all fail, leaving you susceptible to waterborne diseases.

So what exactly are waterborne diseases? How many people are actually affected by them? How do we keep our water clean and safe? How many people are dying from these diseases, and what can we do to prevent that from happening? We’ll answer all of those questions here.

How Much Drinkable Water Is There?

waterborne-diseases

First things first. Before we can understand why waterborne diseases are so prevalent, we need to have a clear understanding of how much drinkable water is actually available.

While nearly 70 percent of the world is covered in water, only 2.5 percent of it is drinkable. And of that, only 1 percent of it is easily accessible, with the rest trapped in glaciers and snowfields.

Since most of the Earth’s fresh water is frozen at the North and South poles, that leaves the rest of the fresh water in surface water and groundwater. Surface water is found in the Earth’s lakes, rivers, and streams. Groundwater is just surface water that has made its way into the soil.

You might be wondering if we will ever run out of fresh water. Our population is rapidly increasing, and most of our uses for fresh water are increasing right along with it. So, will we always have enough fresh water to go around? We will.

The Earth is very efficient when it comes to recycling its water. Every drop of water we use continues through the water cycle. Water on the ground and in lakes and streams is evaporated into the clouds, and then sent falling back down to the ground. Although we may never run out of fresh water, we still need to do our part to be sure we keep it as clean as we possibly can.

What Are Waterborne Diseases?

A waterborne disease is simply any disease that is contracted by drinking dirty or contaminated water. In under-developed countries the water is typically contaminated by human and animal feces or a general lack of sanitation. In more developed countries, it can be caused by faulty pipes, pumps, or purification facilities. It’s even possible to get a waterborne disease by eating food that was contaminated by dirty water.

Industrial Agriculture and the Environment

What comes to mind when you think about farming? Amber waves of grain? Rolling hills and people seated on tractors? The smell of manure? What about pollution?

to pollution, most people don’t think of agriculture. In fact, in order for agriculture to continue, farmers must take good care of the environments of their land and animals.

However, there is a difference between farming and industrial agriculture. While family farms are often maintained over several generations, industrial agriculture is an entirely different thing, and it can contribute to pollution in some significant ways.

We’re going to give you the what, why, and how of industrial agriculture pollution.

What is Agricultural Pollution?

Farmed areas – both on land and in the water – provide vital habitats for thousands of wild animals and plant species. Farming operations that are managed with good sustainability practices help restore and preserve critical habitats, protect watersheds, and improve soil strength and water quality.

However, when practiced carelessly, farming is a great threat to species and ecosystems. Negative environmental impacts from unsustainable farming practices include land conversion, habitat loss, wasteful water consumption, soil erosion and degradation, pollution, climate change, and genetic erosion.

Perhaps even worse is the practice of factory farming. Scientific research has found that factory farming methods – such as confining and overcrowding animals in warehouse-like conditions before slaughter and meat production – create unacceptable levels of risk to public health and irreparable damage to the surrounding environment.

Although factory farms produce an enormous amount of waste and pollution, according to the Natural Resources Defense Council, they are largely exempt from standard air and water pollution regulations. This means that factory farms – which produce more annual waste than the entire population of the United States – can dump their waste as they see fit.

Additionally, as factory farms tasked with raising thousands of animals to meet consumer demand continue to produce tons of waste, our water supply is at risk of contamination. As waterways become polluted with agricultural waste, they lose their ability to sustain marine ecosystems. Populations of marine life are adversely affected, and the food supply becomes contaminated.

Water & Coal for Power

Most of us know that producing electricity requires water. Our most common means of generating electricity is to boil water and use the pressure of the steam to turn turbines. An average coal-fired plant uses as much water as a medium-size city every year. When you add up all the water used by the coal plants in the world, it totals billions of gallons of water that could be used for essential purposes, such as drinking and growing food. Attached is a study by Greenpeace showing water use plant-by-plant. Given that we have plenty of other ways to generate electricity that do not waste our precious water supplies, this is a study in man’s stupidity…or the greed of a few.

Energy-Water Nexus

24 Jul

By Steven Nadel , Executive Director

ACEEE and many others have noted the importance of the nexus between energy and water issues. Energy is used to move, treat, and heat water. Water is vital for producing energy, such as for cooling electric generating plants. Insufficient water availability can increase energy use for pumping and decrease energy production. Flooding can damage both energy and water systems. And there are many opportunities to promote both energy and water efficiency at the same time. Next month we will release a fact sheet on our work on the energy-water nexus and how both energy and water efficiency play critical roles. But first, I want to explore how the relationship between energy and water may evolve in future years, particularly in response to climate change.

Impacts on water supply and demand from Climate change

Parts of the US—primarily in the triangle from Montana to southern California to western Texas—are already experiencing water stress, meaning that water is being withdrawn from water sources at a rate that might not be sustainable (see map on page 272 here).

According to the US Global Change Research Program, as the climate changes, some regions, such as south of the Great Lakes, will get more precipitation and other regions, like the southwest, will get less. A stylized map of expected precipitation changes from their 2008 report is below.

You can’t write about the drinking water debacle in Flint, Michigan, without first recognizing the depth of the tragedy. For more than a year, an entire city was exposed to the risk of lead poisoning. Of the people we already know have been poisoned, more than half are children under the age of six. Those children will suffer neurological damage for the rest of their lives. Long after you and I are gone, some of them will still be living a life diminished. No matter what happens now, that cannot be undone. No overdue apology, no grudging mea culpa, no release of emails, and no state-of-emergency declaration can undo that damage. Take a moment and imagine how you’d react if you were that child’s mother or father.

That terrible fact makes it all the more infuriating that this disaster can’t be called an accident. Instead, it was the inevitable result of a callous and reckless disregard for human life — specifically, the lives of the people who live in Flint, most of whom are black and many of whom are poor. When Governor Rick Snyder released 274 pages of heavily censored emails about the crisis this week, the cruel arrogance on display only made you wonder about the redacted parts that were so much worse they couldn’t bear to make public. Here’s how the New York Times summarized the released portions:

A top aide to Michigan’s governor referred to people raising questions about the quality of Flint’s water as an “anti-everything group.” Other critics were accused of turning complaints about water into a “political football.” And worrisome findings about lead by a concerned pediatrician were dismissed as “data,” in quotes.

The consequences for the people of Flint, though, are but one especially horrible example of what is happening to minority and low-income communities everywhere and every day. Pick any type of pollution — then look to see who is the most exposed and the most harmed. Take lead, for instance. Although lead exposure had declined overall, African American children are five times more likely to be poisoned than white children. Why? In part because the neighborhoods where they live are more likely to have been exposed to lead when cars still used leaded gas. Decades later, children are still paying a price.

Governor Snyder and his Department of Environmental Quality are rightly being castigated not only for ignoring the problem but also for actively denying, in the face of all evidence, that Flint’s water was contaminated. But their culpability for this tragedy extends even further. Before Flint’s water was compromised, its democracy was.
