    I am looking forward to improving my low score on the first post.
    This week in class we learned about specifically were New York gets its fresh water from. On Tuesday Mr. Fox handed each groups four sheets of paper based on a part of the New York City Water System. My paper was based on the Croton Filtration plant while my other group members received a reading about another NYC water system either, Catskill or Delaware or Croton. While reading the articles, each individual in the class room had to jot down notes about their article and be prepared to share their notes to their group members so they can jot the notes down as well. I learned the progressing on the Croton filtration project, what it was, and its importance.
    I felt like the Articles helped me understand the NYC water system and projects that are being created or improved. I felt like I was the “expert” on the Croton Filtration plant. When I was able to explain to my group members, I understood my article even more. Also, my group members had other articles. While listening to the notes they jotted down, I understood their article with just the most important facts.
    On Wednesday, Mr. Fox gave the class a project and we had to pick a paper from the cup. The paper in the cup was going to have the name of the system you would have to write about and later on make a booklet with it. When I picked the paper and it was the Croton Water Filtration. Luckily, I had already became an “expert” on my group on this system and I had the article sating facts about it.

    I'm looking to improve my score of the first blog.

    In this short week of classes we truly find out where our water comes from, a question that I was doing myself for several days and that finally I can answer correctly to anyone who ask me.

    The water we, the residents of NYC, use comes from 3 systems: The New Croton Aqueduct, which supplies 10% of all the water of New York, the Catskill Aqueduct, which supplies 40% of the total water used and the Delaware Aqueduct which supplies 50% of the water used by the New Yorkers.

    The New Croton Aqueduct, built between 1885-1890 to replace the Old Croton Aqueduct for a large water supply, is the oldest of the 3 systems that supply the city of NY, crosses the river Croton, has a length of 31 miles long and runs from the New Croton Reservoir in Westchester to the Jerome Park Reservoir in the Bronx, delivering its water to certain areas of the Bronx and Manhattan. Supplies only 10% of the total water used daily in NYC due to the current deterioration in which it finds, by being in the middle of a densely populated area.

    The Catskill Aqueduct, built between 1907-1924, crosses 1.100 feet below the Hudson River, is about 55 miles long and runs from the Ashokan Reservoir in Olivebridge, New York to the Hillview Reservoir in Yonkers, New York, supplying 40% of the water used in this city without need to be purified.

    The Delaware Aqueduct, built between 1939-1945, is the newest of the three water systems that supply NYC, takes its water from the Rondout Reservoir and ends its tour at the Hillview Reservoir in Yonkers, New York, supplying 50% of the water and also being the second longest underground tunnel in the world with 85 miles long.

    The Catskill Aqueduct and the Delaware Aqueduct are both located in the Upstate of New York City in the Catskill Mountains and provide 90% of water used in this city, which does not need to be filtered because it is naturally purified but unfortunately over 37 millions gallons of water per day escape by 2 leaks from these systems.

    Thanks to these 3 systems of water more than 9 million people in NYC have access to clean water and directly in their homes, using the residents of this city more than 1.2 billions gallons of water per day. The 95% of this water is delivered by gravity, saving us millions of dollars in their extraction.

    We are lucky that we have clean water, delivered by gravity, coming directly to the faucets of our houses, and for those reasons we must take care of the water, a privilege that not everyone in the world have but that we all in the world need.

  3. This week in Environmental Science we talked about 3 systems: The New Croton Aqueduct, which supplies 10% of the water of New York, the Catskill Aqueduct, which supplies 40% of the water we use and the Delaware Aqueduct which supplies 50% of the water used in NYC. A aqueduct is a small canal that contains fluid.

    This is important because the water system is economical and flexible, because of aqueducts. This is because approximately 95% of the total water supply is delivered to the consumer by gravity. Only about 5% of the water is regularly pumped to maintain the desired pressure. As a result, operating costs are low.

    In conclusion this is important because the water eventually ends up in our home once we turn on the faucet. New York water system is really important because we re-use water. This is why in New York people do not pay for water. In other states like New Jersey (suburban) people do pay for water. People use water everyday so it's so important.

  4. This week in Enviromental Science we learned about the New York City water supply. In my group the sheet i got was Tunnels at Croton water Filtration Plant in this sheet it also showed the process of water filtration. The water tunnel was drilled and blasted through 880 feet of rock and the treated water tunnels were excavated using a tunnel boring a machine. The process of water filtration is
    1. Water from the Croton watershed is pre-treated with chemicals to optimize particle removal in filtration process.
    2. Pre-treated water will be clarified in a dissloved air-flotration, will fprce 90% of suspended particle to the surface of the water.
    3. Clarified water will be filtered through sand and anthracute coal to remove the remaining particle.
    4. Filtered water will be disinfected with ultraviolet light before it is chlorinated and discharged the treated water tunnels to the distribution system.
    5. Concentrated solids removed from the water will be pumped to a wastewater treatment plant.
    Also DEP provides more than one billion gallons of water each day to more than nine million residents.

  5. This week in class we covered the importance of where our water comes from. We then in class we read an article called "History of New York City's Water Supply System. In this article we covered the topics of reservoirs, aqueducts and watersheds. They each have their own importance for example reservoirs are an artificial lake used to store water. It was created by the construction of a dam or exculpation into the ground. An aqueduct is a water channel,a way to carry water. A watershed is all of the water under or on top of an area of land that drains into the same place. Delaware River watershed is the main source of water that we drink constructed between 1937 and 1945. Over 3.7 millions gallons per escape from two leaks. This means that a big amount of water was being wasted, which then does not benefit us because if water is being wasted then at the end we would then be left with no water to survive in.

    This is important because people take advantage of the water, and people dont realize the amount of water that they are using daily. Being able to conserve the water helps the community and the world because, by helping we can then stop all the damages that have been made, because of water conditions.

    In conclusion it is important because water is a major role in life, if we don't have anything water how are we suppose to survive? My answer to this is that we wont be able to survive because we need liquid in our system. If we don't we would die of hydration. We are lucky to have clean water that allows us to not catch any sort of disease. Clean water is what we need and what we now have, that they did not have before.

  6. I AM looking foward to improve my lowest blog post score.


    This week we learned about our different water resources . I learned about the Croton & Catskill/Delaware Watersheds.
    The croton is one of the largest surface storage water that is unfiltered. The system delivers more than 1.1 billion gallons of safe drinking water. The croton watershef is 375 acres and is located east of the hudson river . The croton is one of six reservoirs located in the catskill mountains

  7. This week we learned about the different ways New York City recieves their drinking water. we have aqueducts which are water channels. We also have reservoirs that are dams that keep water preserved and stored when its needed. Lastly, we have a watershed these are man made lakes, streams and tributaries in order for a vaste amount of water to drain into a specific place. This is important because it is important to know where we are getting our water. We dont think of this much because we have such fast and no-hassle access to clean water but maybe that should also be a reason to check out where our water comes from we spend thousands of gallons of water in one day alone and we only have 3% of fresh water on the Earth that we can use so how is it possible that we have so much water to spare. When you look into it more and do research such as we did you see that water is conserved by using it and then also collecting and storing the water when it rains. This way we have the water as fast as always and clean enough to do the domestic work.

  8. I would like to improve the score I received on my second blog post.
    This week in environmental science I learned about where New York City’s water originated from. One of the questions which I felt was important to ask myself is, “Where does my water come from?” There are 3 bodies of water in a glass of water which you may or may not drink on a daily basis. These bodies of water consists of The New Croton Aqueduct, which supplies 10% of all the water of New York, the Catskill Aqueduct, which supplies 40% of the total water used and the Delaware Aqueduct which supplies 50% of the water used by the New Yorkers.
    However, there has been an ongoing problem occurring underneath our feet, New York City’s water is transported by gravity through 2 city tunnel. Tunnel No. 2 is in desperate need of repair. There are leaks that accumulate 36 million US gallons of water per day. This water may be essential since the earth only has 3% of freshwater left, it is to conserve as much as we can.
    I have continued to make positive changes in my water consumption, and it feel good to know that I am making a difference in our ecosystem. These changes are able to preserve as much water as we can and will be very beneficial to us in the long run.

  9. I want to improve my score of the first blog post.


    During the first week of Environmental Science we learned about the amount of water we use in our daily lives. We used a chart to calculate the amount of water we use for sanitation, consumption and other uses. At the end we learned how much water we use per week and per day.

    I was really shocked at the amount of water my peers and I use per day. Per day I use 163 gallons of water, but in my class there are people that use more than 400 gallons. The first thing I thought about was how when I’m brushing my teeth I leave the faucet on and also how I leave the faucet on in the kitchen for a long time when washing dishes. We as a society are using up all this water and not really thinking about it. There are people around the world that don't even have access to clean water and have to walk miles and up hills to get water multiple times a day. For example in some villages in Africa women and children have to constantly walk with multiple buckets each to get water. Still they are appreciative for the bit of water they get, while we have access to water and are literally throwing our water away.

    This topic we learned about connects to the other thing we learned in environmental science, which is that in the entire world we only have 3% freshwater and the other 97% is salt water. Just because in the map we see large bodies of water doesn’t mean it is all useful. This is very petrifying to me because 3% is not a lot and there many people on Earth using up this water. Many people say that why can’t we just remove the salinity from the salt water. This is a good idea but it will cost the United States an abundant amount of money. I think that if we all make a pact as a community, state and country we can help try to conserve this limited amount of water we have.

  10. During this short week of school we have learned about precisely where our water comes from. 50% of the city’s water comes from the Delaware system, 40% from the Catskill system, and the remaining 10% comes from the Croton system. In New York City the water is said to be very clean so there is no need for it to be filtered, however starting next year I think it is the water coming from the Croton aqueduct will start to get filtered. I remember when my family used to drink water straight from the faucet. I don’t know why they stopped though now both of my parents only like drinking bottled water. They consider the faucet water to be dirtier over the years. To me if it’s an emergency and I have to drink the water from the faucet I don’t mind but I don’t think is all that sanitary. I know that the water we drink at school is from the faucet and I drink it so I’m thinking is all mental. Depending on the place that I am at like a school or a hospital I would consider the water to be cleaner than as if it was my house faucet. The pipes are taken care more carefully in an environment like school or hospital not so much a building where I live that is been around for decades. Is really mind changing though after learning that the water we use now is reused repeatedly for centuries. It also makes you think why people even bother to buy bottled water if is the same water being drank and used over and over again.

  11. This week in environmental studies we learned about multiple topics but the one which really caught my attention was the Catskill / Delaware water system. I found this topping interesting for the reasons that I wonder where the water I use comes from. the Catskill/Delaware system produce 90 % of the water used by NYC residents.

    The Catskill/Delaware system produce 90 % of the water used by NYC residents. I found this interesting because as a New York resident I wonder where the water I use comes from. Knowing the amount of people that reside in New York I predicted that there would be more water systems and I believed that the water from this city came from the great lakes. A question that came to my mind was how big is the Catskill/Delaware water system, and how many gallons of water does the Catskill/Delaware pump to New York city.

    This has changed the way I think about the New York water system because now know where the water I use comes from, it also makes me realize how water from the city its not obtain from a local water supply. I would like to know how old is the Catskill/Delaware system is, also I would like to know how often does it get repaired.

    This week I am looking forward on receiving a higher grade on my blog post. This week we been working as group and independent, on Tuesday Mr. Fox gave out four articles and we all had to take one and read it. While reading it we had to take notes and underline the most important fact that we found on the article. The article I picked was Croton Water Filtration Plant, while reading this article I learned that once completed, the plant will represent a significant step on improving water quality of the one million New Yorkers who rely on the croton water system the city oldest which began in 1842. When we came back to our group my peers were able to understand my article and I understood theirs, I even kind of started thinking how the four articles connect to one another.
    On Wednesday we had to pick out a topic from a bag that Mr. Fox had, I was the last one on choosing so I got City Tunnel Number 3, it started in 1970 and it will be completed in 2020. Tunnel number 3 was needed to help supply the entire city and relieve pressure on the other, older tunnels. This is being created by the DEP (Department Environmental Program) this project turned out to be $6 billion dollars. The way the DEP is building tunnel number 3 is by mechanical rock, and tunnel boring machines.
    Building tunnel number 3, benefits our family and friends because the Department Environmental Program are trying to make things better for us. They are trying to make everyone receive the amount of water that they need and relieve pressure from tunnel 1 and 2.

  13. This week in Environmental Science we talked about 3 Aqueducts systems. First is the New Croton Aqueduct that supplies 10% of the water of NYC. Also, there is the Catskill Aqueduct that supplies 40%, finally the Delaware Aqueduct supplies 50% of the water used in NYC. Before this class I had no idea about where the water I used came from. The significance in this is that now I’m aware that the water I use daily comes from far away (not in the city that I live in). This importance in this is that an aqueduct is a small canal that contains fluid. An aqueduct is designed to transport water by gravity.

    The fact that New York City water department is able to get the water very economically is so important because New York City water demand has grown increasingly over the decades. This is because the population has grown dramatically.

    In conclusion, an aqueduct is important because the water eventually ends up in our home once we turn on the faucet. New York water system is really important because we reuse the water. This is why New Yorkers do not have to pay for water. In other states like New Jersey (suburban setting) people do pay for water. People use water everyday so it's an important resource. If I was put in the situation where the water had to be payed I would definitely not use as much water as I currently use daily that being 443 gallons daily.

    I want to improve my score from the previous post. Thank You so much for helping me today after school on my blogpost, Mr. Fox.

  14. his week of class we learned where our water comes from. we learned about reservoirs, aqueducts and watersheds. reservoirs is basically where NYC reserves their water for the use of the people.An aqueduct is an underground tunnel that provides the water to the state it travels through pipes underground.watershed is where all the water goes mostly under ground all water in a watershed goes to the same place.Most of NYC’s water comes from upstate.NYC water is considered to be the cleanest water in the country, I belive it is all my life I have drank from the faucet I barely drink bottled water only occasionally . I belive tap water is clean and not a danger at all.

  15. I’m looking forward to improving my grade.
    In this week, most people became aware of where there water comes from. We learned about 3 different places/sources that are the main resource of where our NYC water comes from. What we learned today should really impact most of our lives because most of us don’t treasure water as in other places. That is because we don’t know the process that water has to go through in order to reach us in NYC. But now we do. First we learned about aqueducts, which are mostly like water channels, where water is mostly pushed by gravity. We also learned about Croton Catskill/Delaware Watersheds. These places are located in the western/southern part of New York State (upstate). Its location is high above New York City; there is where the gravity part comes into play. It’s where the water that 90% of New York City residents use is stored. Most Watersheds use aqueducts where the water travels in a tunnel and makes its way towards NYC. Most of these water tunnels are about 100 years old which worries many in thinking that our water isn’t fresh. We not knowing where our water comes from makes us insecure and undecided. People not knowing that our water system is the system that contains the freshest water in most of the world. You can actually drink water straight from the faucet and not filter it, and it’s still fresher than ever. I think that people should become more informed and updated which simple things such as this. Therefore they won’t have worries and second thoughts on how to use things, such as water.
