In the past week, my group and I have gathered information from Chandler’s Pond. There we tested Dissolved oxygen and pH levels of the inflow and outflow pipes and the temperature of water and air temp. Dissolved oxygen is an amount of measure of gaseous oxygen really dissolved into aqueous solution. Oxygen gets into the water by diffusion from the air and plays a role in waste product in it’s own photosynthesis. Ph is a measurement of acidity or alkalinity of water. It ranges form 0-14.

Dissolved oxygen is an amount of measure of gaseous oxygen really dissolved into aqueous solution. Oxygen gets into the water by diffusion from the air and plays a role in waste product in its own photosynthesis. While performing the dissolved oxygen test u should have all your materials and it should be performed on the site. Dissolved oxygen is necessary for good water quality. Oxygen is removed from the water from respiration and decomposition of organic matter. In the winter dissolved oxygen is usually more concentrated and higher in the winter than in the summer in less there is signs of animal and plant life around. During raining season it tends to be even more concentrated because of the oxygen mixes with the rain air as it falls. http://www.state.ky.us/nrepc/water/wcpdo.htm

pH is a measurement of acidity or alkalinity of water. It ranges from 0-14. If the pH is 6.9 or lower the water is acidic. And if the pH 7.1 or higher the water is basic. The normal pH of water is 7.0. The pH goes up and down naturally because of the carbon dioxide CO2 carbon dioxide in water comes from the fish’s metabolism. pH is important in pond water because if the pH is very low or too high the fishes are going to be harmed. Ph is common in swimming pools and aquariums so it can be treated because if it is to low or too high it can burn your skin and very bad for your body, it is not healthy. Ph needs to be basic because if not aquatic animals can die. http://www.water-research.net/Watershed/phosphates.htm Are there differences in pH and D.O. at 2 different sites, 1 inflow pipe site and the 1 outflow site? There was a difference between the inflow and outflow pipe because when we 1st went to go test the pH and the dissolved oxygen of the inflow pipe, we got 6.0 for the pH and 8ppm for the dissolved oxygen, comparing to when we tested the outflow pipe the 1st time and got a 8.0 for pH and 10ppm for dissolve oxygen which are numbers higher then that of the inflow pipe. When we we tested the pH and the d.o of the inflow pipe a 2nd time we got 6.3 for the pH and 6ppm for the d.o, and again testing at the outflow pipe we got 7.0 for pH and 7ppm for the d.o. So in conclusion the pH and dissolved oxygen of the outflow pipe is higher then that of the inflow meaning the outflow pipe water is much more dirty then inflow pipe.
