There are unidentifiable pollution issues that affect the Rio Grande Valley where I reside. Some of these are bacteria, salinity, and chemical pollution. Although some of the pollution is from agricultural runoff, some is also from maquiladoras, or assembly factories in Mexico. Although these sources are technically point-source because they pollute directly into the river, they can equally be called non-point source to the US, because the US cannot control them. The US does not have direct access to their sources (USGS, 2009). Many town or villages in Mexico also dump their sewage directly into the river. They too are out of the US’s control and will probably not amend their practices anytime soon. The US does have issues with industrial waste. In Laredo, TX, many industries dump their waste directly into the river. Pollutants include arsenic, mercury, chlordane and DDE and are present in fish in the river (Hener, 2009). The bad thing is that many border corridor towns in Texas get their drinking water from the river. Although water quality reports show that drinking water is within EPA guidelines (City of Mission, 2012), I cannot allow myself and my family to drink this water without the constant fear of contaminants on my mind. More E-Coli-aid with your dinner…yes please!
I will continue to purchase bottled water as long as we live here.
