It should be highlighted the presence of iron in the irrigation ditch of Rascanya above the permitted parameters established in mg/l. It seems a punctual waste or there is a seasonal reason as a further analysis shows the iron concentration.
We also found high ammonium concentration in the Albufera (3 mg/l versus to 0,5 mg/l permitted). It could be due to the use of fertilizers in the fields of rice close to the lagoon.
-
The variations of the values, especially for ammonium and iron, can not directly correlated with environmental impacts, because there is a lack of accurancy in the analyzing system (in all countries the same range of variation could be observed).
-
Therefore for the surface water in all countries the parameters measured are in a good range, within the limits of the EU.
-
The variation of the oxygen values are big, because the measurements were taken in winter and summer. There a no informations for the values of the EU for the seasonal variations.
Geography in Altenburg

Around Altenburg there are many hills and mountains. These are mostly occupied by forests. However, we also have a river that calls Pleisse. Unfortunately, this is problematic for the inhabitants in Altenburg and surroundings, because if there is too much rain for many days can flood come. Normally it is in the spring or autumn. Here trees can be uprooted, houses can collapse and the streets are flooded. It can also happen that a village will be completely closed off from the environment. This is not good because then people in this compartment are not be able to acquire new foods, not medication and have get the hardest case, no more drinking water. I was such at a flood. The worst part was that one all the time the water has heard. We know it is possible the water can collapse the house. With us there were fatalities. Our neighbor was very ill and had to take powerful medication, but could not get new. Not even the firefighter was able to push their way past the floods and help us. We could nothing do about it, except to hope that good weather is so that the water evaporates more quickly and we were able to get food again. At the end everyone was happy when the water was gone, we could again get food and we had electricity.
How it could happened? Unfortunately, the water had no place. In the last years it was lots of new building in the country side. Perhaps we should pay more attentions in the future that the nature needs more space.
Comparing Wateranalysis Spain - Europe

COMPARING WATER ANALYSIS FROM SPAIN WITH EUROPEAN PARAMETERS
After analysing some samples of water carried in Albufera, Dehesa, Acequia de Rascanya, it can be said that the water quality is good considering the quality parameters that the European Union states in the Water Framework Directive 2000/60/EC.
It should be highlighted the presence of iron in the irrigation ditch of Rascanya above the permitted parameters established in mg/l. It seems a punctual waste or there is a seasonal reason as a further analysis shows the iron concentration
We also found high ammonium concentration in the Albufera (3 mg/l versus to 0'5mg/l permitted. It could be due to the use of fertilizers in the fields of rice close to the lagoon.
Water hardness is high. The hardness in CO3-2 is 12º d and total hardness is 27º d. This hardness comes from the environment along which surface water is mainly limestone. Although this fact does not make it undrinkable, it has to be taken into account for the consumption of newborns and people with kidney problems.
Hardness is also important to maintain electrical appliances such as washing machines, dishwashers and kettles, where the accumulation of lime could damage them.
The second samples analysed in Valencia, (between the towns of Xiva and Picanya) show us that ammonium levels are above European regulations. Water hardness is more or less in the same levels that samples taken in la Albufera and Acequia de Rascanya. The rest of the parameters are lower than European quality parameters.
When we analyzed the water in the River Turia, we saw that the ammonium, the carbonate, the pH and the phosphate are almost like the European parameters, but the nitrate are lower and there are no nitrite according to the European parameters. The chloride is a bit lower than the European parameters.
In all of cases we found a water with a high amount of oxygen, that indicates us that the water is good enough to preserve the flora and fauna of the different places we were working.
In summary, we can say the water analyzed in Valencia (Spain) is in a good quality, having european laws like a reference, despite little quantities of some ions that could probably come from agriculture customs. If this is the reason, fertilizers should be reduced or controlled in the areas which had been studied.
