Bottled Water at Union

Posted on by

I used to be a bottled water guy. It was always cold, and guaranteed to be clean.

It was simple. When I was thirsty, I got a bottle of water. Drink, dehydrate over the course of a few hours, repeat. Though it varied from day to day, I would estimate I used to drink about 5-6, 16.9 fl oz. bottles of water every day. For those of us who like to try to show our mathematical prowess by completing simple equations, that’s 84.5-101.4 fl oz. of water a day.

Which, in the grander scheme of things, is roughly the suggested intake of water on a daily basis (currently 91 fl oz.). Yet, I was wasting all the plastic that had to contain that water, one plastic bottle at a time. I stopped drinking bottled water when I started actively trying to reduce my carbon footprint. I bought a reusable bottle, and I fill it up periodically from a fountain.

But in the case of the broader Union community, I see people with bottled water all the time. As I sit here writing, I count 4 people around me with plastic bottled water in some form or another. And I didn’t even count a fifth, who has a cardboard box of water, which proclaims itself to be “better” because “Boxed Water is Better”.

Let’s assume the average Union student drinks the suggested daily value of water, and Union has roughly 2,200 undergrad students. Let’s say half (being generous) consume bottled water while the other half consumes water more responsibly.

(1/2) x (2,200)=(1,110)…(1,110) x (5.5)=(6,105)

Following this logic, Union’s student body on a daily basis consumes over 6,000 bottles of water. That’s a staggering number. Even more staggering: the sheer cost of producing so many bottles of water.

According to a February 2007 Pacific Institute Report: “Bottling water produced more than 2.5 million tons of carbon dioxide…It took 3 liters of water to produce 1 liter of bottled water.”

This is, of course, not to mention what happens to these 6,000+ bottles of water afterwards. Are any re-used? What percentage are even recycled?

Drinking water should begin follow the same tagline as their counterparts in the alcohol industry.

Drink Responsibly.

 

Water Sustainability and Food Choices

Thinking about what I want to eat for dinner, I don’t often consider how my choices are impacting the environment. The agriculture and livestock industries require massive amounts of water; with this said, some choices for dinner are more environmentally sustainable than others. According to Kai Olson-Sawyer, a Senior Research and Policy Analyst in the GRACE Water and Energy Programs, “the total amount of water needed – to produce one pound of beef is 1,799 gallons of water; one pound of pork takes 576 gallons of water. As a comparison, the water footprint of soybeans is 216 gallons; corn is 108 gallons”. Thinking about the amount of fresh water required to raise livestock vs grow crops, choosing a plant-based diet is much better for long-term environmental sustainability, due to the extreme strain on our water resources from the livestock. The extensive amount of water required to raise animals comes partially from how much the animals need to eat and drink, as well as the number of animals that are produced in our massive food industry, especially in the United States. Due to the large differences in water requirements for production, plant-based diets contribute to much better environmental sustainability than diets that include meat.

Changing the Course of Water Sustainability

Sustainability efforts continue to rise as awareness of the ecosystem’s demise becomes more of a global priority. Due to the increasing efforts, the need to identify the most effective plans of attack is also increasing. In terms of water sustainability, Will Sarni has identified three ways the course of water sustainability changed in 2017.

One of the most notable changes is the increasing efforts to more efficient tracking of water data. New public policies, like California’s “Open and Transparent Water Data Act,” require a statewide platform that combines various databases in order to provide the public with the most comprehensive water and ecological platform possible. The collaborative database highlights numerous issues, like water scarcity and climate change, that otherwise may go unnoticed. Other technological advances include more powerful sensors that track water quality, water usage, asset management, and water utility economics. The new technology can also provide a more accurate set of predictive analytics, keeping the public as updated as possible.

Although we are heading in a positive direction, certain large corporations continue to be huge contributors to the negative water usage. In an investigation by Christine MacDonald, Coca-Cola is identified as a huge source of false advertisement talking about its own sustainability efforts.

The company promised in an advertisement in The New York Times that “For every drop we use, we give one back.” Coca-Cola conducted a self assessment of their product which revealed that it took 35 Liters of water to make every half liter of Coke. The company promised in 2007 that its goal was to sustainably source 100% of key agricultural ingredients, but the follow through on this promise has been seriously lacking.

Coca-Cola isn’t the only offender of over using water. MacDonald reported that it takes 712 gallons of water to produce a single t-shirt and 462 gallons to produce a quarter-pound hamburger. People don’t realize how much water it takes even to produce the simplest of things. In the United States alone, the per capita Water Footprint is 2,060 gallons a day.

 

The Water Footprint of Alfalfa and Meat

Agriculture accounts for 80% of water consumption in California. This mainly accounts for the growing of the plant Alfalfa. Alfalfa is a plant grown to feed livestock. Beef consists of a large portion of the American diet. In order to feed these animals the production of Alfalfa is increased significantly due to the increase in demand for a beef hungry diet. Beef has a water footprint of 4 million gallons per ton produced. This is far more than any other crop.

Additionally, the way that meat is being produced today is different than it was decades ago. Because the meat is not being handled the same way, when it does not reach standards of the FDA this also means that water is wasted. According to a New York Times article, when 8.7 million pounds of beef are wasted that is roughly equivalent to 631.6 million gallons of water wasted. That is equivalent to about 15 million barrels.

If we relied less on a meat heavy diet and replaced 50% of the animal products normally consumed, there would be a 30% decrease in an individual’s water footprint. If individuals had a vegetarian diet, their water footprint would be decreased even more to about 60%. Seeking out less meat hungry diets will help to conserve the amount of water used for Alfalfa.

The Water Footprint of Livestock

After researching the effects of raising livestock and poultry for meat, I found that the negative consequences were even worse than I expected. The total amount of water needed to produce one pound of beef is 1,799 gallons of water and one pound of pork takes 576 gallons of water. (Food Tank). As a comparison, the water footprint of soybeans only takes 216 gallons of water. Beef requires the largest amount of water because the bigger the animal, the more resources required such as more drinking water and water to clean etc. However, the resources that beef requires goes way beyond just water. The thousands of pounds of food cows are fed such as corn require large quantities of fertilizers, land, and fuel for farming machines, and lead to more fossil fuels and pollution. This ties into our class discussion about how cows produce large amounts of methane.

This issue is important because global meat production has doubled and will continue this upward trend. It is difficult to suggest people to become vegetarian, but reducing meat intake by 1/3 could lead to a 1/3 reduction in water usage. There is not a single human activity that affects the planet more than raising livestock.

This photo gives a visual of how water usage sky rockets due to the consumption of beef.

 

Water footprints

We have discussed the CO2 emissions of beef and naturally, the amount of water it takes to produce this beef by raising cattle is extraordinarily high. However, it is just just cows that contribute to our global water footprint, every product does, but especially animal products which require so much water to raise an animal. The Water Footprint Network provides an interactive model that shows how much water it takes to produce many of the foods and products we use daily, including chicken.

According to the article, the average water footprint of chicken is 4330 L/kg, or about 519 gal/lb. Although this quantity is less than other common animals such as cows (15,400 L/kg) or pigs (6000 L/kg). It is important to use tools like this to visualize how our food choices impact the global water footprint.

Fighting Water Waste

Give an example of water waste (in U.S. or other countries). Make suggestions for reducing water waste and quantify the amount of water that could be saved.

 

According to an article in The Washington Post, Americans wasted 1 trillion gallons of water in the year 2015. But how much really is 1 trillion gallons? Our water waste accounts for 9% of the water needed to solve the California drought problem, which has a deficit of 11 trillion gallons of water. It is also equal to 40 million swimming pools, 24 billion baths, or Lake Okeechobee in Florida.

 

The EPA states that a lot of the water we waste is due to leaks. The average household wastes nearly 10,000 gallons of water per year due to leaks. Ten percent of households waste more than 90 gallons of water per day due to leaks. Not only does this waste American’s water, leaks also waste American’s money. Fixing household leaks is both cost effective and an effective way of reducing waste.

 

Besides household leaks, there are a number of other ways to reduce our water waste. Making small changes to our lifestyles is one way to effectively reduce water waste. Individuals can try and take shorter showers, or even turning off their water after wetting their toothbrushes. In addition, I believe more water saving toilets should be installed in public bathrooms, as well as in households, in order to reduce waste. The toilets in our Reamer Campus Center are designed with two different flush settings and help reduce the amount of water used when going to the bathroom. I think that if more of these toilets were installed on campus in places like dorms and Minervas, the Union College community could effectively reduce our water waste.

The Ecological Impact of Almonds

Do you substitute half&half with almond milk? Or do you snack on almonds for a quick stomach fill? Well, I do. Oddly enough, I have never considered the ecological footprint for the production of almonds, have you? Well, according to the well-regarded California Almonds Organization, it takes 1.1 gallons of water to grow a single almond. In a classic serving size, there are 23 almonds. This calculates to 25.3 gallons of water used to make only 1 serving of almonds. The amount of water used per one serving of almonds is more than quadruple the amount of water used for an efficient dishwasher to run or for an efficient toilet to flush according to the in class activity. Also, 99% of the total production of almonds comes from California. California also produces 80% of the world’s production. As California is in a current drought, and the fact that almonds require 10% of California’s total water supply each year, one could say that this statistic is astounding. But, if you were to purchase 1 quart size container of almond milk, and use it for your cereal or in your coffee, you are consuming less than half of a serving of almonds, which is about 12.7 gallons of water, which is comparable to 5 loads of laundry. The effect of the amount of water required for almonds must be relatively compared, like all products. This is exemplified by comparing the amount of water required to produce 1 gram of protein from almonds and beef. For almonds, 1 gram of protein requires 4 gallons of water, while for 1 gram of beef; 27 gallons of water are needed. As for water amount, it takes 6 times less the amount of water to produce protein out of almonds than it is from beef.

Water Waste

According to Livescience, 70% of the world’s freshwater supply is used for agricultural purposes, such as farms and lawns. This poses a problem for the environment because when fields are watered, the excess water flows into nearby streams or rivers. This can pollute bodies of water because the runoff is filled with fertilizers and other toxins that may be harmful to marine life. Also, some crops require more water than others. For example, cotton needs a lot more water to survive than potatoes do.

As we discussed in class, another source that requires a lot of water is the toilet. Everytime you flush, you are using between 1.6 gallons and 4 gallons of water. After this water is used, it may be treated and sanitized so it can be used in other ways, such as for watering plants.

Another common way that people waste water is through leaking and malfunctioning equipment. According to the Washington Post, Americans waste 1 trillion gallons of water each year, or 40 million swimming pools, due to leaky faucets and broken sprinkler systems. Not only is this wasteful and harmful to the environment, but it is extremely expensive for homeowners.

One way to reduce the amount of water waste in the world is to replace older toilets with more efficient ones. Also, landowners and farmers should replace their irrigation systems with sprinklers, which produce less runoff. Additionally, people should be wary of potential leaks in their faucets in order to avoid wasting any water.

 

How much water is in a glass of wine?

It takes 872 gallons of water to produce 1 gallon of wine. Scaled down, it takes about 34 gallons of water for a 5 fluid ounces of wine, according to Huffington Post. But how is this even possible? How come it takes so much water to make wine? What is drought-stricken California doing to conserve water while remaining one of the largest winemaking regions in the world? The water consumption required to cultivate wine includes water used on the vines, water used in the winery and rainwater (crops consume the rainwater). The grapes for the wine require constant irrigation especially in drought-stricken areas such as California and parts of the Mediterranean region. It is important to note that wine grapes require about one-third of the amount of water used to grow almonds, so I guess we should all drink less almond milk and more wine? In the winery, the water use is mostly focused on sanitation. The barrels, tanks, presses and crushers are cleaned and disinfected after every. single. use. Even if the the equipment will be used to make the same type of wine. Wineries are, however, working to use less water. Many wineries, especially in France where crop irrigation is legally regimented, have converted to drip irrigation and today’s advanced technology allows for hoses that can sense when to turn off. Many wineries have adopted onsite water treatment systems so all that water used to clean the equipment can be recycled at the winery. I think it’s safe to say that wine will continue to be consumed all around the world but sustainable technologies and practices must be adopted in order to drink wine guilt free.
