A History of the Rio Grande River:
The Effects of pollution on the Environment and the Health
of the People Around the Southern Rio Grande River

The Rio Grande River is an important water source for both sides of the Border. Different environmental laws on each side of the border have led to different managements of this important water source. It is important to understand the effects of pesticides, waste and garbage disposal on the river in order to identify the effects on the environment. With a large wildlife refuge in and around the southern Rio Grande and that this is the main drinking and irrigating source for a very large populous the effects of pollution on the environment must be understood. In this case if the Rio Grande has been affected by years of pollution than what, if any, are its effect on the population?
Coming from the Rio Grande Valley of South Texas I have always heard of the polluting of the Rio Grande River. Dangerous pesticide used in the Mexican side, industrial waste, and human waste disposal have been the blame for the pollution. Yet this has brought to mind that the Rio Grande River stretches for over a thousand miles and many on both the U.S. and Mexican side have used it for over a hundred years. So then what would be the affects of years of continued pollution on the Rio Grande River to the environment and people of the Rio Grande Valley. In order to understand this there must be an analysis of all aspects associated with the Rio Grande River.
Document Base.
This paper will incorporate all relevant aspects associated with the Rio Grande River. Using several water quality reports from 1945, 1975, 1992 I will attempt to reveal any patterns in pollution from one time period to another. This will also enable me to know the extent of pollution during each of the time periods as well as reveal the differing degrees of pollution up stream and down stream.
The use of scientific works of fairly recent analysis on specific contaminants in the water can help us to understand the levels of these contaminants and what are their effects on the environment. This will further assist in understanding the effects of pollution not only on the environment but also on the health of the people around the river. The study of the risk of contact with the river by Konvicka is especially important since many individuals have direct contact with the water be it from drinking, bathing, or recreational.
We must also take into account the politics of this area concerning pollution. Since the Rio Grande River divides two different governing bodies than there are different laws concerning pollution. Zinke's document will shed light on these laws in Mexico and in addition will expose any ineffective enforcement of these laws. The laws concerning pollution in the U.S. will also be taken into account even though there is an understanding that the U.S. tends to be stricter as well as better able to enforce their laws.
This recent trade union between Mexico and the U.S. is relevant to the treatment of the Rio Grande River in that it has increased industry in the area and may contribute to further pollution. Yet Garvey's document can reveal the details that have to do with the environment within NAFTA and explain any changes to environmental laws or avenues by which to pursue changes.

 

Analysis:
I suspect that polluting on the Rio Grande River has gradually increased throughout the years, only slowing down within recent years. Yet because the river divides two countries of different economical stability, any attempt to end dangerous levels of pollution will be more difficult. We must also take into account that the Rio Grande Valley lies at the southern most point of Texas and Northeast Mexico and any pollution upstream will, in one way or another, affect them downstream.
This pollution of the Rio Grande River also brings into mind that not only does it effect the environment but the people around it as well. It will be interesting to analyze the health problems within this area and in doing so I believe there will be a higher level of health complications ranging from stomach viruses to birth defects.
Overall Plan:
The plan of developing this paper will be set in a chronological order. The paper will first begin with an early analysis of the river from its water quality and the pollutants affecting the river to the inhabitants around the area and their contribution to the problem. The next section will introduce new environmental laws, its effectiveness, and a shift in the economy to industrialization, some of it due to NAFTA, and new affects on the environment. The following section will touch on the relationship of individuals with the river and any health problems due to the polluted river. The final section will conclude explaining any continued problems surrounding the pollution of the river, its connection to health and revealing any contribution to or against the problem by NAFTA.
