----------- 

Climate change has been heavily studied and reported in the media.  For this discussion each student should read the peer reviewed article below and also pick one or more news articles discussing the same topic.  After reading the articles address the questions below. 

Everyone read the original peer reviewed article: Widespread Biological Response to Rapid Warming on the Antarctic Peninsula

In addition choose one or more of the following news articles to read:

Address the following questions:

  1. Summarize the peer review article in your own words.
  2. Compare the peer review article to one (or more) of the news articles.  In particular discuss what ideas were the main focus of each and the predictions each made. 
  3. Did you note any biases in either source?
  4. Which source did you prefer and why?
  5. Comment on at least two other students' posts. 

Always cite all your sources in MLA or APA format and respond to at least two classmates (see discussion grading rubric). ------------------------------------------------------------

In the provided article, Widespread Biological Response to Rapid Warming on the Antarctic Peninsula, it focuses on the changing temperature over time. The article identifies that moss is growing more and more in this area due to the warming climate. This means that the environment is changing in ways that promote photosynthesis and growth for moss. Over the last 150 years, the moss has started to grow more rapidly. The significance behind it is that it tells us that the climate is continuously getting warmer, further promoting the needed conditions.

The article I chose was the one provided by National Geographic. This article is basically a mirror of the initial article. It mentions how Antarctica’s ics melting provides more water for the moss and allows it to grow. Alongside, the rising temperatures give the moss longer growing season. In both articles, it states that the cold weather diminishes the rate of decomposition of the moss, so it just accumulates as it grows.

Neither article seemed to contain any bias. I preferred the peer review article more simply because it contained more information and graphs to back up its research.

In the article, “Widespread Biological Response to Rapid Warming on the Antarctic Peninsula”, examines the climate change happening on the Antarctic Peninsula. The case study examines the growth of moss compared to rising temperatures over time. Over a century and a half there has been rising in the temperature causing the growth of moss to become more rapid. The rapid growth of moss and rising temperatures in the Antarctic, it is a combination for major change in environmental and geographic areas. In the article “Fast-Growing Moss Is Turning Antarctica Green”, there were many similarities with the “Widespread Biological Response to Rapid Warming on the Antarctic Peninsula” article. The information that was given in the National Geographic article had many similarities. The peer review article definitely had more statistical data and graphs explaining the statistics. Some of the similarities were that temperature rising in the Antarctic Peninsula, the receding of Ice caps causing rock and vegetation to be exposed, and how the ground is saturated with water from melting caps helping spring the moss growth. Both articles were great. I enjoyed reading the article by National Geographic. For me, it was really an easier read. The peer review article was difficult in understanding with all the statistical data and information. I did not see any bias in either article. Overall both great article with wonderful information. If I were doing a research paper over the rapid growing moss in the Antarctic Peninsula I would make much use out of the peer review article.

Part 1: Sewage in Your Home

Do you know how sewage is handled in your home? Do you have a personal septic tank or is there a sewage management facility in your community?

Determine how sewage is handled in your home. Post your results.

Part 2: Wastewater Treatment

As discussed in the lesson, there are several ways to treat wastewater and the sludge resulting from the treatment process. Wastewater is often released in different areas depending on where you live. Do you know where the wastewater from your community goes? Take a moment to check the local treatment plant's website, or stop by and visit or give them a call and find out the answers to the following questions. Post your results.

Part 3: Area Question

1. By visiting a wastewater treatment plant near you, checking their website, or making a phone call, determine   

a. What is used to disinfect water: chlorine or ozone?
b. Upon treatment, where is the wastewater released?
c. What methods are used to treat sludge?

2. Visit the EPA sites and write a brief report (250 words) on guidelines for treatment of sewage.   

ALWAYS cite your sources in MLA or APA format and respond to at least TWO classmates (see discussion grading rubric)

PART 1

  1. I live in Valdosta, a city, within a subdivision. All the sewage is handled by the City of Valdosta.

PART 2

  1. The wastewater for Valdosta, GA goes to the Mud Creek Treatment Plant (WPCP) and the Withlacoochee River WPCP.

PART 3

  1. By visiting a wastewater treatment plant near you, checking their website, or making a phone call, determine 
    1. What is used to disinfect water: chlorine or ozone? Ozone is used to disinfect our water.
    2. Upon treatment, where is the wastewater released? The water is kept on-site and pumped to the consumer as needed.
    3. What methods are used to treat sludge? Sequencing Batch Reactors are used. SBRs mix live bacteria and air to oxidize organic matter and rids of any inorganic solids.
  2. Water is one of the basic necessities for human life. Without it, the human race would come to a complete halt. EPA made many policies that water treatment plants must abide by before water can be deemed either reusable or fit for release back to nature. The Clean Water Act (CWA) is the most renown policy under EPA’s dictation. It was originally called the Federal Water Pollution Control Act in 1948. It was later renamed the Clean Water Act when it was amended in 1972. Along with these amendments, came new regulations. The CWA made it illegal to release any pollutant from a point source into navigable waters unless they had a permit. This amendment is undoubtfully the most important of the many amendments. This is due to the fact that the National Pollutant Discharge Elimination System (NPDES) controls the discharges now. The NPDES requires industrial, municipal, and other facilities to obtain permits if their discharges go into surface waters. Individual homes that are connected to the municipal system or have a private septic tank do not require this permit. Another amendment that came along was the requirement for records to be kept for when sludge is introduced to land. In conclusion, the Environmental Protection Agency and the Clean Water Act of 1972 regulate and enforce rules that keep our environment free and clear of pollutants. It sets strict guidelines, so companies do not dump waste wherever they please. Without it, sickness and fatalities would be on the rise from the amount of pollutants exposed to the environment.

Part 1: Sewage in your home

I live in a city so the sewage is taken care of by a facility. Macon water authority manages the sewage within the city. The sewage goes through sewage pipes and taken to the macon water authority.

Part 2: Wastewater Treatments

The sewage goes through many different stages. Preliminary, Primary, Secondary, Tertiary, and the final stage of disinfection. In preliminary treatment is the first stage that involves influent waste entering and treatment plant, having many of the solids removed. The primary stage involves a more sophisticated settling take, which removes most of the solids that will float or settle. The secondary stage is the process that features a highly controlled artificial environment that allows microscopic organisms to feed on waste. The tertiary stage is used to improve the quality of the water even more. And the final stage is disinfection, which reduces any remaining bacteria and viruses and helps protect the public from exposure.  

Part 3:Area Questions

a. What is used to disinfect water: chlorine or ozone? Water is disinfected by chlorine

b. Upon treatment, where is the wastewater released? Water waste is released back into the rivers and streams

c. What methods are used to treat sludge? The Rocky Creek Plant is an advanced secondary wastewater treatment facility utilizing the extended aeration activated sludge process, followed by conventional filtration.

There are many different things that go into the treatment of wastewater. The proper treatment of wastewater is very detrimental to public health. With the proper treatment of wastewater being vital to public health, many policies were put in place. Policies such as the Clean Water Act and Safe Drinking Water Act. The Clean Water Act (CWA) of 1972 (the Law or Statute), as amended, has been the primary Federal Law in the U.S. governing water pollution and has been central to our country’s endeavors to improve the quality of the environment.  It is among the most important factors responsible for the general level of good health enjoyed in the United States. Sewers collect sewage and wastewater from homes, businesses, and industries and deliver it to wastewater treatment facilities before it is discharged to water bodies or land, or reused.
