It was our task to find out how intensive the pollution of certain brooks and lakes in southern Duisburg is. Maps This map shows Germany's position right in the heart of Europe . The State of North Rhine Westphalia and the Lower Rhine Region are situated in the northwest, having a common border with The Netherlands and Belgium. The field trip and the tests were made under the guidance of our geography teacher, Dr. R Gaida.
All measurements are higher.
We suppose that warm, slightly alcaline liquids, which are rich in ion and especially in phosphate, were dumped into the brook. Wildfoerstersee gets a lot of clear groundwater, but at the same time it receives slightly polluted water from Haubach. Entenfang has the cleanest water of all. From Entenfang via Haubach to Wolfsee conductivity and phosphate concentration rise. We suppose that pollutants were dumped in, too.
