Water Pollution

Group members: Starr Winburn, Diamond Smith, and Pearl Smith

Project question:  What are the levels of nutrients in the bodies of water around Lincoln

 

Goal: The goal of the project is to test for levels of nitrogen and phosphorous and see if there is any human influence in their levels.

 

Task: Take water samples from different bodies of water and use a water sample kit to test the nitrates and the phosphates.

 

Location: This test can be done anywhere where there is a body of water.

 

Materials: The materials you will need thermometer, water kit samples, bowl with string, distilled water, eyedropper, and glass tubes.

Background: The purpose of this project was to test for the different kinds of nutrients  of different bodies water. Phosphorus is an essential plant nutrient. Addition of phosphorus to a lake from sewage treatment plants, failing septic systems, urban and agricultural fertilizers, and dense waterfowl populations can stimulate excessive plant growth and upset the lake’s natural food web interactions. In many lakes phosphorus is the least available nutrient; therefore its abundance controls the extent of plant growth. Nitrates are a ester or salt of nitric acid. It has an indirect effect on aquatic life. However, excess levels of nitrates in water can create conditions that make it difficult for aquatic insects or fish to survive.If there is an excess level of nitrates, plants and algae will grow excessively. Excess plants in a body of water can create many problems. This will cause an unstable amount of dissolved oxygen. We collected water samples from different bodies of water, use solution bottles, and document the results in epicollect and/or data sample sheet. We did this every day for four days but starting at different times for each day.

 

The purpose of this project is to take water samples from different areas at different times to see the difference between the bodies of water. This can be accomplished by using the solution bottles kit. It includes nitrate, nitrite, ammonia,  and also phosphate. Remember too much of nitrates will make create an unstable amount of dissolved oxygen. Also addition of phosphorus through treatment plants, failing septic systems, etc can create excessive plant growth which will upset the lake’s natural food web.

  • Eye droppers
  • Epicollect (if possible)
  • Data sample log

 

Methods:

  • We collected water from different bodies of water
  • We used the water sample kit
  • We documented the results in epicollect and/or data sample sheet
  • We did this for four days straight, everyday at different times

Preliminary Findings: As you can see in the graph above on different dates at different bodies of water the levels of nutrients changed. Now what may happen while doing this project is that it will not always changed drastically or you may just get the same result.

Other things that you will be able to do:  You can also test for algae and try to take samples from other different bodies of water. You can collect more data and test for pollution and make inferences on the animals.
