Abstract

This study involved collecting water samples from the headwaters and mouth-waters to analyze their geological, chemical and bacterial qualities. The LA River has gone through a long process of channelization; this changed the river water itself. This pavement has resulted in significantly deteriorated water quality and a loss of habitat for much of the river. The river is arguably an unused source of water in California. To potentially use the water for anything other than a sewage transport system we must analyze the river water. The hypothesis constructed, that the overall water quality of the mouth waters will be better than that of the headwaters, was tested through several biology and chemistry experiments made on 2 gallons of water collected from each site. The locations were geologically analyzed on site to compare the physical properties of the water and surrounding water bank. It was observed that the head waters and mouth waters had very different physical properties, where the head waters exhibits a foul smell, a high turbidity level. In contrast, the mouth waters was observed to have a higher level of hardness, and a salty smell, with a significantly lower turbidity. Through the experimental procedures, the presence of several ions, such as calcium, lead, magnesium, and iron, was determined in the headwaters as well as the presence of coliform bacteria. We concluded that the quality of the Head LA River Water was in fact in worse condition than that of the mouth waters. However the Mouth Water was found to have high levels of sodium and calcium, high hardness, therefore showing an extremely high amount of dissolved solids present in the mouth of the river. Future research could focus on different sites to find out the area where the biggest environmentally hazardous chemicals are added to the river.
