Korean Scientist Discover that Han River is Polluted

It took a while, but Korean scientists have discovered that the Han River is polluted:

Non-point pollution refers to environmental deterioration of pollutants from urban residence, roads, farms and construction sites. It is created when rain falls or snow melts, with the runoff picking up and carrying topsoil, bacteria, fertilizers, pesticides, oil and many other toxic or harmful materials and depositing them into various water sources. It is so called because it is difficult to determine a single, polluting source. As land development accelerates and areas where water cannot permeate increases, such pollution is emerging as a new environmental challenge.

According to the Ministry of Environment, non-point pollution accounts for 30-35 percent of water pollution in South Korea; if environmental deterioration from decrepit sewage and untreated animal urine is included, the number could increase to 42-69 percent.

The team is led by Oh Jae-il, a professor majoring in Housing and Environmental Engineering, and conducted the research between 2004 and 2005, by analyzing the degree of pollution in runoff water collected from Yoenhyo Brigde, one of the bridges crossing the Han River.

Silly me, here was all this time thinking USFK was the reason the Han River was polluted.  What I want to know is when is someone going to study the effects of the sewage sucking trucks dumping their loads in the river?
