For some reason the audio on my video is not working. Nevertheless, this video shows all the ways that my roommates and I are attempting to be more sustainable in our apartment. The first clip shows that we try to take shorter showers and turn off the water as we brush our teach. The next clips exhibits that we keep doors and windows open opposed to using electricity for a fan or air conditioner. The third clip displays all of our reusable cups that we use opposed to using one-use plastic water bottles. The last clip shows our washer machine that we use using cold water opposed to hot water because it’s better for the environment.

Single Use Plastic Bottles per Week

Single use plastic water bottles are very bad for the environment, typically because they are not recycled and are often thrown out. The plastic takes centuries to full decay and as plastic decays it leaks dangerous chemicals into the groundwater and soil. Even if plastic is recycled, it might not be recycled properly and would still need to decay on the earth. The total carbon footprint of one plastic water bottle is about 828 grams of carbon dioxide. Lots of college students use single use plastic bottles for water, coffee or any other drink. These cups are typically thrown away, adding to the amount of plastic waste in the world. This chart shows that the average number of single use plastic bottles per week is 3.9 amongst the sample size that I gathered data from. The lowest number per week was 0, due to my friend’s constant usage of a reusable water bottle and the highest number was 9. That means per week a college aged student similar to my friends would use 3.9 single use bottles adding up to a 3229.2 grams of carbon dioxide per week released due to this plastic waste.

Gallons of Water Wasted Per Day

For this week’s bog topic, I thought it’d be interesting to reach out to my friends and see how many gallons of water that they believe that they waste a day. Water waste is a huge issue when it comes to sustainability across the globe. Water can be wasted in many different ways and I feel that is often over looked. For example, keeping the water running when you brush your teeth, taking too long of showers, pouring out drinking water, etc. After reaching out to 10 of my friends, I put the data into a bar graph, which is pasted below;

The range of answers is quite obvious as one of my friend’s stated that she doesn’t waste any water, meanwhile, another one of my friend’s claimed that she wastes 20 gallons of water a day. By asking my friends this question, it was intended to make them think of all of the ways that they waste water and in return think of the ways that they can reduce water waste. Making these small changes can have a big impact on our globe.

Water is Life

Water. Water is an essential part of human life on Earth. We as humans are made of water, use water everyday, and need water to survive. It helps regulate all of our functioning parts of our complex bodies and ensures benefits of living a healthy life. Just as humans are extremely dependent on water, so are many other species such as the group of livestock. One animal in particular is cows, which are heavily connected to greenhouse gasses and Co2 emissions. Depending on the temperature that a cow is living in, the weight of the cow, and whether it is producing milk or not, correlates to the amount of water it needs daily. It has been estimated that for cows, “Daily water intake may vary from 3 to 30 gallons per day depending on age, body size (weight), stage of production, and the environment (mainly air temperature).” With an increase in temperature or lactating cows, this requires more clean water for them. But to put the stat of 3 to 30 gallons in perspective, every human is advised to drink 8 cups of water per day, which is half a gallon of water. So although cows are much larger than humans, their daily water intake is extremely large and crucial for them.

Water is an essential to everyday life but there is a ton of water being wasted annually in the United States. An article published by the Washington Post states, “The incredibly stupid way that Americans waste 1 trillion gallons of water each year.” 1 Trillion gallons of water is another worldly large number and the ways depicted that Americans waste water are water leakage, hoses, and irrigation systems: all are not needed waste methods of water. One way to prevent the wasting of water would be to be more aware of how you are potentially wasting water. This can be from fixing leaks immediately, shutting off your sprinkler system when not needed, and using less water related activities such as dishwashing and laundry. If there was to be less water wasted, the number conducted through the Washington Post of 1 trillion gallons, could be minimized by millions and millions. Not to mention saving water waste, but this can save thousands of dollars spent by homes and businesses.

One method of intaking water that is very popular is through bottled water. It is so popular because it is pre bottled, convenient, and can be disposed of. Although it is not economically and environmentally friendly, Americans live a fast paced life and want the fastest way to intake water. To put water bottle usage in perspective on Union College’s campus, let’s first say there are 2,200 undergraduate students. I’d say about half of the students here use plastic water bottles daily, so 1,100. If every student is drinking about 3 bottles a day, that’s 3,300 approximately, plastic water bottles. To calculate the amount of oil used to produce and ship the water to Union, I estimated around 15,000 gallons of fuel to get the water from Western states all the way to Union College.

Water Usage and Utilization

Posted on by

Water is a necessity for us humans along with planet Earth. Humans can go much longer without food as they can without water. It is interesting to think that a lot of the food that we consume could not possibly be produced without water. For example, think of crops that need water into order to grow. Or, all of the water that livestock drinks that we eventually consume such as pigs. This idea alone shows how important water is in its comparison to food consumption.

Consider the following, “There is the same amount of water on Earth as there was when the Earth was formed” (epa.gov). Furthermore, “Nearly 97% of the world’s water is salty or otherwise undrinkable. Another 2% is locked in ice caps and glaciers. That leaves just 1% for all of humanity’s needs — all its agricultural, residential, manufacturing, community, and personal needs” (epa.gov). This idea is really hard for me to wrap my head around. I think about how much water I myself personally use on the daily. Then, I think about how many humans are on this Earth and how much water is used for humanity’s needs by the whole planet. This alone proves how much water is on this Earth. I find this fact so interesting seeing how human production as well as global warming has affected our water usage. In my opinion, bottled water is so popular because of the convenience of it. Consider, reusable water bottles have to be constantly washed and sometimes they are a bit pricey. Bottled water is convenient as once you finish the water, you can just throw away or recycle the bottle. If I had to estimate the bottle water consumption on Union College’s campus, I would estimate that around 50% of Union’s students drink bottled water opposed to water from the tap. Furthermore, I would average that of the 50% of bottled water drinkers, they drink at least 2 bottles of water a day. Based on Union College’s enrollment being around 2,300 students, 65% of that is 1150, multiplying that by 2, my estimate is that Union College consumes around 2,300 bottles of water per day.

Bottled Water

This week’s theme of water had me thinking about bottled water and the growing popularity of reusable water bottles within my generation. It got me thinking about the waste produced by bottled waters–how much CO2 would it take to produce enough bottles of water for each student on campus to get their necessary daily intake of water?

The average human needs to drink 3.7L of water per day, and each plastic water bottle is around 1L of water. There are 2,050 students at Union, and if everyone drank the recommended amount of water per day, that would total 7,585L of water, and 7,585 plastic water bottles. According to Luqel, to produce 500ml of a single use plastic water bottle it takes 82.9g of CO2. How much CO2 would be produced to create 7, 585L of plastic water bottles, then?

Well, 500ml is equivalent to .5L. .5L produces 82.9g of CO2. .5L doubled is 1L, and 82.9g doubled is 165.8g of CO2. To produce one 1L plastic water bottle, it takes 165.8g of CO2. For all of the 2,050 students of Union to drink 3.7L of water per day, it would take 1,257,593g of CO2(7585 x 165.8).

That is just for one day of water. For a year of water? It would take 459,021,445g of CO2.

This is just something to think about when considering reusable vs. one use plastic water bottles. Not to mention the microplastics!

Goats, Sprinklers, Union College

  • One example of livestock that uses water: Goats consume: 3 gallons/ 1 day x 365 days/1 year x .0038 tonnes/ 1 gallon= 4.161 tonnes/ year per goat
  • If a typical gardener uses a sprinkler gushing 12,240 gallons/ 1 monthly x .0038 tonnes/ 1 gallon x 1 year / 12 months= the Gardner will use 3.876 tonnes / year 
  • Water waste could be reduced by doing laundry more infrequently (each load requires about 12.5-19.6 gallons per load depending on the washer and according to prudentreviews.com), adding timers to sprinkler systems (where according to bigsprinkler.com it takes 27,000 gallons to irrigate 1 acre of land) and especially by eating less beef which according to denverwater.org requires 1,847 gallons of water to produce.
  • Bottled water is a matter of convenience and one of appealing marketing. Our susceptibility to innovative marketing techniques makes us prone to consuming water-on-the-go. To estimate the student consumption of bottled water, assuming no student is using the hydration stations and only acquiring water from bottled water the following “ideal” situation may arise:
  • There are 2050 students at Union, 47% women, 53% men
  • 3.7 L/day per man x 1 gallon/3.785 L x 365 days/year = 356.80317 gallons per year per man
  • 1086 men at Union
  • Approx. 387,488.243 gallons per year per Union men
  • 2.7 L/day per woman x 1 gallon/3.785 L x 365 days/year = 260.369881 gallons per year per woman
  • 964 women at Union
  • Approx. 250,996.565 gallons per year per Union women ideally
  • It takes one liter of oil to prod. one bottle of water, 

Take the Distance: 7,933 mi xWeight: 2916.247 tons x 161.8g of Co2/1 ton x 1 mi = 3743176249.57 g of Co2 it takes to ship in a 747 Boeing, with 2 passengers at roughly 197 lbs, with roughly 650,000 gallons of water to hydrate Union College.
