| Note générale : |
Nitrogen and phosphate pollution of surface water by various potential sources is discussed in general attention is paid to the more or less natural sources: precipitation, leaching of natural soil constituents, seepage of saline groundwater and to the artificial sources: domestic waste water, inlet water from storage canals, leaching of fertilizers, surface runoff and discharge of dune water. For three polders and three book catchmont areas the total nitrogen and phosphate load has been calculated. Polders and catchmant areas differ with respect to the geo - hydrological situation, soil,type, agricultural soil use and population density. In the sandy soil of the brook cathment areas on the other hand, the nitrogen pollution originates for the largest part from scattered agricultural sources. The contribution to the phosphate laod by domestic sewage depends on the population density and the treatment method of waste water, out generally speaking it is an important factor. |
