Drinking Water - Example 1
Difference Surface Water - Ground Water ?
The fundamental difference is the absence of biopolymers in ground waters.
In river waters biopolymers originate from diffuse run-off from top soils or sewage effluents. A high N/C ratio, thus a high amount in proteinic matter is typical.
In lakes, biopolymers originate from algae and exhibit a low N/C ratio. This material is primarily polysaccharidic.
In ground waters biopolymers should be absent. If not, then either a hydraulic contact to a surface water or a high microbial activity in the aquifer can be inferred.
