The seepage of Nitrogen compounds in the water detmermine that the KH value of the soil system has allowed a large amount of nitrogen to enter in the aquifer. If the values of these soils were even lower we would get a lower concentration of nitrogen in our samples. Although they are reasonable but lower KH would have been much appreciated as it would have inhibited the seepage of contaminants in the soil.
Yes more sampling will help us in getting a better perspective of what happening inside the aquifer and hence it will give us with better options for the usage and sanitation of water. Although some samples reveal that water at certain areas is potable after simple processing however, water present at certain areas would require advanced filteration and purifying techniques. So we would require additional samples to investigate where we can find suitable water.
Yes tritium dead water is although not as good as the natural water but we can still use it and it does not cause any serious harms to our body.
Discharge can because of vegetation and other pumping techniques. However, in the absence of streams discharge is still quiet low but the value is maintained because of vegetation, domestic wells, etc.
Yes we can see that there is an approximate balance between the values observed. Although it is not much but we can ascertain that the balance is somehow maintained.
Yes if we assume that the value of nitrogen is conservative only then we can calculate the residence time of water with the help nitrate ratios.
Nitrate contamination can only be averted by using better and lower nitrogen fertilizers, other than this we can use horizontal spill methods that would somehow minimize the concentration of nitrogen in water deposits.
Although using the lower aquifer is not wise at all and it would create an imbalance in the aquifer which might allow seawater to enter in the aquifer and contaminating the whole deposit. But we can see that currently this appears the only possible way to meet the requirments of both parties. They can use upper aquifer water after filteration. Although this would be costly but it will prvide long lasting benefits.
