Dear Global Water Sampling Project:

Our starting hypothesis was that the water in Peters Creek would be contaminated because of the surroundings.  It is a stream in a populated area in a fairly large city.   After we tested the stream, we found that we were very wrong.  The pH levels were good, the dissolved oxygen was high, and the nitrate and phosphate levels were low. 

Some of the things we noticed in the creek were several kinds of fish, water striders, and small water snakes.  The water was clear, and there was very little algae on the rocks and the bottom.  Thank you for allowing us to do this project.

Lake at Independence Grove Forest Preserve  

After all the sample collecting, testing and data analysis, we have come to the conclusion that the lake we tested at Independence Grove is healthy and the water quality is very good.  We compared our results with the expected values and found the following:

the pH was perfect at 7

nitrates were .5 ppm which is considered excellent

phosphates were 1 ppm which is considered excellent

dissolved oxygen was 6 ppm which is considered good

turbidity was 2 meters (measured with a secchi disk) which is considered good

temperature was 21 degrees Celsius

The above results support our hypothesis that Independence Grove Lake would be one of the cleanest lakes in the project.  We also found a relationship between temperature and dissolved oxygen when we plotted the results on a graph which indicated that as temperature increased, the DO levels decreased and as temperature decreased, the DO level increased.  These results were to be expected.

We learned many things by participating in this project.  We learned how to use different equipment to collect samples, how to test those samples and what the results indicate about lake quality.  We also learned about the quality of other lakes, creeks and rivers from around the United States and other countries around the world.  If we do participate in the project again, we would like to have more schools from around the world participate so there would be more data to compare.

 Thank you for the opportunity to participate in this project.

Global Water Quality Sampling Project  

The Global water quality sampling project was a project which studies and records water qualities from around the world. I, as a participant, helped record data and found astonishing results…

As I looked at the results of a scatter plot graph, I realized that Dissolved Oxygen and Temperature are dependent on one another. I recognized that the lower the temperature became, the higher the Dissolved Oxygen became.

It was also interesting to analyze the data and find the Biological Oxygen Demand was relatively low compared to the dissolved oxygen which means that the site’s oxygen supply is at a healthy level and the organisms living in the body of water are not suffocating. It also means that there is room for population growth.

In the end I was surprised to find that there were no nitrates in the water because after looking at the data from other schools, our data was of high quality. We had one of the highest dissolved oxygen tests recorded, we also had a low Biological oxygen demand. In the end I was somewhat disappointed that other places do not have water as clean as ours, but as an end result I’ve discovered that we as citizens of Oakland, Maine have water of very good quality!
