This investigation compared the water qualities of Cherry Creek and Bear Creek in order to determine how the physical, chemical, and biological factors of the streams impacted the amount of life present within them. This investigation attempts to answer the question, “How are abiotic elements related to the number and abundance of macroinvertebrates found in the two streams?”
Water quality is the term used to indicate a body of water’s suitability for use (Ayers 1976). Water quality can be assessed based on its physical, chemical, and biological characteristics that it portrays (Metcalfe 1989). All of these elements interact together to create the ecosystem in which an organism lives in. The investigation looked at the physical parameters, temperature and water quality of the streams, and the bioindicators present within the streams.
The physical parameters consisted of observations regarding the physicality of the streams. That is, how wide and deep the water was, and how fast was the flow rate of the water. These elements are important because they affect what kinds of organisms can survive in different parts of the water. Some organisms may not be able to survive in deeper waters, whereas others may not be able to survive if

The independent variable, water quality, will be determined through the measurements of pH, temperature (measured in degrees Celsius), phosphate, nitrate, ammonia, dissolved oxygen and dissolved solute levels (all measured in parts per million) in the water. The dependent variable will consists of the number and abundance of different types of organisms and plants present in the streams.
If the number and abundance of macroinvertebrates is dependent on the quality of water in the streams, then Bear Creek will have a greater abundance of macroinvertebrates due to its better quality of
...they affect water loss from animals and plants so affect where the limpet will live. The factors were measured with a CEM 4 in 1 Environment Meter (Light, Sound, Temp, Humidity Meter), which I got from a store which looked like this (http://www.digital-meters.com/humidity-c8/handheld-c58/cem-4-in-1-environment-meter-light-sound-temp-humidity-meter-cem-dt-8820-p61)

which could out compete the organisms of the upper pool when in a more benign environment.
In the news we hear about all the problems with water pollution in third-world countries, making the problem feel sort of foreign to us. However, water pollution is much closer to your home than you might think. As a matter of fact all kinds of different pollution affects us all the time, it can be in the food we eat, the air we breathe, and the water we drink. Pollution has plagued our beloved Buckeye Lake and we intend use the process of dredging to provide a short-term solution, until another, more permanent solution is put in place.

One of the tests that we did was called the critter count. In that experiment, we found several rocks in the creek and looked at them closely to discover what types of bugs - critters - were on them. The largest number of stream insects and crustaceans we saw were in group 1 where we saw 49 critters. In the second group, we found 13 critters total. In the third group, we saw 12 critters. If the water was polluted, we would have seen a bigger
There are many causes and solutions to the deterioration of the Colorado River. The Colorado River is not the great river it used to be, with an abundant amount of healthy water, thriving wildlife and abundant plant life. With climate change, water salinity, pollution, and natural runoffs, the river’s water quality has deteriorated immensely. However, if communities and environmental groups join forces to research and raise money to find ways to help improve the Colorado River, it can get back to its original condition. This issues affects those who live by the river, concluding that I live somewhere near the river, I would love to see a change in the rivers condition to not only help the nature around it, but to help myself and others.
About 80% of the state's surveyed freshwater rivers and streams have good water quality that fully supports aquatic life uses, while 17% have fair water quality that partially supports aquatic life uses, and 3% have poor water quality that does not support aquatic life uses. Ten percent of the surveyed rivers do not fully support swimming. The major sources of impairment are agriculture, responsible for 53% of the impaired river miles, urban runoff, responsible for 16%, and construction, responsible for 13%. These sources generate siltation, bacteria, and organic wastes that deplete dissolved oxygen. Only 17% of the surveyed lakes in North Carolina are impaired for swimming, and 6% are impaired for aquatic life uses.
“Don’t waste that water! Kids in Africa don’t even have water to drink!” Almost every American has heard this saying before. We have heard this because there are water shortages in third world countries like Africa, as seen in the movie “Blue Gold”. But why have we developed this notion that there are only water shortages in third world countries? When in reality, there is a shortage of water right here in our home country. The Colorado River’s water is high in demand as it serves millions of people, powers industries, and is home to all different kinds of wildlife. The Colorado River will not be able to keep up with the increasing demand of water and soon enough the river will go dry. Organizations like the Colorado River Water Users Association are trying to change the way that the water is used and adjust how it is managed. The Colorado River is drying up and the western states are running out of water, however, public policy is trying to regulate and preserve the Colorado River to make it more sustainable in the future.

After doing some research, we have found out more about each kind of organism found in the stream.
Water is one of the most essential non-renewable natural resources on the Earth. Technically, an un-hydrated human being can live no more than three days. In the United States, people consume water mainly from tap water and bottle water. However, the consumption between these two sources is not even but lean to one side heavily. According to the Natural Resources Defense Council, people consume from 240 to over 10000 times more per gallon for bottled water than they usually do for tap water. (NRDC) In addition, according to a survey from US National Library of Medicines, only 17% of the participants prefer to drink tap water exclusively.(US National Library) Compared to the bottled water which is shining like a superstar, tap water is like a diligent worker in the shade, unpopular but useful. The extremely unbalance of bottled water consumption implies that a commonly hold conception exists: bottle water is superior to tap water. In fact, scientific evidence proves that tap water is nothing different than bottle water. More importantly, the excessive consumption of bottled water is an irrational use of resources and creates severe environmental issues.
