What Is The Importance Of Water Quality?

Introduction:
Water quality is the scientific measurement describing the cleanliness of water and/or the condition of the water being studied. Factors that used to describe water quality are pH, Dissolved Oxygen, Temperature, Turbidity, Nitrogen, Biological Oxygen Demand (BOD), Fecal Coliform, Phosphate, and Total Solids. Water quality is important to know because water is a necessary part of life, and people need to know how clean the water they’re using is. Water quality is important for the preservation of water on Earth and the animals and plants that need water. The quality of water in coastal environments is influenced by various human influences, such as fertilizer from farms and lawns, discharge from water treatment plants, oil

The temperature of the beach water are slightly higher than in the harbor because of the location, there is more sunlight hitting the waters. The sample that was taken was also in a shallow open area versus in the harbor that was in a shady deep location. Average pH

Figure two shows the average pH in both the surface (8 ppm) and bottom waters in GH, as well as the average pH in GHB (7.8ppm). The bottom and top of the harbor water were the same pH because pH does not tend to change much in deeper waters. The pH of the waters at the beach were slightly lower than at the harbor because the acidity in the water was lower because of the lower run-off rate, versus high levels of run-off at the harbor. Average Salinity

Figure three shows the average salinity in both the harbor and the beach, by the tools used to gather the data. In the Bottom of the Harbor measurement of salinity was 40.5ppt while the surface came to 35.8ppt while using the YSI. The Harbor salinity measured to 33.5ppt with the refractometer. The Harbor salinity measured to 30.5ppt with the hydrometer. The beach salinity measured to 32.2ppt with the YSI. The beach salinity measured to 25.7ppt with the refractometer. All together the average beach salinity calculated to 25.7ppt with the

The main points of the study were to examine the two different locations (Good Harbor beach and Gloucester harbor) and discover differences, possible impacts, and to examine the waters to see what lies beyond the shore and to investigate the water quality. GH is a harbor with a depth of greater than 5 meters. GHB is a beach with a depth of less than 2 meters. The difference in water depth is likely a cause of the wide temperature range between the GH average temperatures (16 C⁰) and GHB’s (19 C⁰), as the water with the greater depth is getting much less warmth from the sun than the water with the greater depth. GH’s water is largely oceanic; the tide and waves coming in and out are it’s main source of water, while GHB is partially salt marsh; a point where freshwater streams and fresh groundwater mix with the salt water from the ocean. This is why GH’s salinity (which is 38.15 ppt with the YSI and 30.5 ppt with the hydrometer) and GHB’s salinity (which is 32.2 ppt with the YSI and 25.7 ppt with the hydrometer) are so different. For the same reasons that the salinity is different, there is a slight difference in pH. (8 and 7.8 for GH and GHB, respectively). At the time of data collection, there was very little water movement at GH, with much more happening at GHB such as people walking through the water, waves, animals walking around and wind movement. This is the most likely
