The following diagram shows nitrogen sources and concentration levels in the groundwater of a coastal city

The following diagram shows nitrogen sources and concentration levels in the groundwater of a coastal city LB0nr

The given chart describes the concentration level of nitrogen in the groundwater portion of a coastal city due to the various sources of leakage of nitrogen. The information is evaluated and important points will be explained in the following paragraphs. Firstly, the waste disposal placed on land and leakage of chemicals from storage tanks mixed with groundwater level due to mechanical problem. After this, domestic and market gardens, add a fertiliser's dangerous particles and households liquid waste enter in the groundwater level. These sources get down in groundwater level due to soil particles. Secondly, nitrogen oxidisation by lightning and nitrogen fixation by vegetation also contribute a nitrate amount in groundwater level. After the whole process, the nitrate particles flows into the same direction with salt - water interface and discharge through groundwater discharge zone into the ocean. In the conclusion, it seems to me that the whole process of nitrate particles in the groundwater to ocean makes it clear the stages involved in the procedure.
