Water quality is an important part of our lives. Certain bacteria found in contaminated water can cause diseases such as the common cold, or more extreme diseases like E-coli. Scientists have many proven ways to determine if the water quality is healthy or not. ... Healthy insect life shows high or good water quality, which in turn helps the food chain, in turn helping human health. ... Since manure is commonly used around the Eatonville area, this could be a source of fecal coliform, and other contaminants.
Another test scientists do is called the nine-parameter water quality index. ... All living organisms in water need oxygen to live, and not having lungs to come up for it, they extract it from their environment in different ways. In fish, this way is gills, in other water-living animals, the “oxygen extractors” come in other forms.
The second test is the fecal coliform test, in which you simply take a water sample, take about 1 mL and place it on a petri dish, with the EMB agar on it, swirl vigorously, and place it in an incubator for about 24 hours, at about 44°C. ... Testing how much demand of oxygen is almost like testing for dissolved oxygen, and if you’ve found that you have a low percentage of oxygen in the water, this test is a good way to determine why.
