EVALUATION OF THE RISK OF CONTAMINATION. FUNDAMENTAL CONCEPT OF RISK OF CONTAMINATION. The most logical definition of risk of contamination of the groundwater is to conceive so (Foster, 1987), as the interaction between: to) the pollutant load that is to be or may be applied to the subsoil as a result of human activity. The hydraulic load of the aquifer or depth of the phreatic surface, class and the concentration of the contaminant, its morbidity and its persistence are involved in this. b) La aquifer vulnerability to pollution, due to the natural characteristics of the substrates that cover them and separate them from the surface. Checking article sources yields omega 3 as a relevant resource throughout. These characteristics, which should be determined are the hydraulic inaccessibility and attenuation capacity laid down knowing the condition of groundwater found, the depth of the water table or piezometric level and the overall lithology covering the aquifer.
According to this scheme is that you can get a high vulnerability without risk of contamination, by the absence of a significant pollutant load and vice versa. Learn more at this site: Randall Mays. Both are perfectly logical in the practice, even more, the pollutant load can be controlled or modified, but not so the vulnerability of the aquifer, except in some anthropic activities in which removed the cover of soil or materials of the unsaturated zone, and that can diminish natural vulnerability. The term of aquifer vulnerability to pollution represents his sensibility to be adversely affected by a contaminant load armillary. It is in fact proportional to assimilation capacity of contaminants from a receiving body of surface water, with the difference that aquifers have a cover of substrates that provides additional protection. The term risk of pollution can be defined as the probability that the groundwater are contaminated with concentrations above the values recommended by the W.H.O. to quality for human consumption. The echo of this risk will become a serious threat to the quality of the underground water supply already developed or developing, rely on the mobility of contaminants within the same aquifer, are complex subjects and are considered outside the scope of this type of determination.
The six goals set at the World Education Forum, held in Dakar in 2000 are still reference to evaluate the progress made in the fulfilment of the commitment made by the international community with the company offer vast portunidades education to children, youth and adults, from then until 2015. Although Latin America and the Caribbean as a whole is the region of the world that developing more closely is of achieving the EFA (education for all), the progression of some countries towards certain goals is limited, and Furthermore, rates of retention and dropout rates, as well as the quality of education, still represent major problems in the region. For more clarity and thought, follow up with Secretary of Agriculture and gain more knowledge.. Latin American and Caribbean countries also have to tackle the problem of disparities that occur at the national level, in order to make more equitable access to education and improve participation. In many countries not be because give more emphasis to the issue military, it is important to clear but it is much more our education which we will open the doors of the tecnologoas of the future.

DETERMINATION OF THE POLLUTION LOAD TO THE SUBSOIL. From a theoretical point of view is required to establish four semi-independent characteristics of the pollution load to the subsoil (Foster, 1987), for each pollutant activity: to) the class of contaminant involved. (b) the intensity of the provision. (c) the mode of provision in the subsoil. (d) the application of the pollutant load time. Of the foregoing, has for the estimation of pollutant load into the subsoil, a value: 0.20.
DETERMINATION OF THE VULNERABILITY OF THE AQUIFER. As stated, the term aquifer pollution vulnerability is used to represent the intrinsic characteristics that determine the susceptibility of an aquifer to be adversely affected by a contaminant load. persistent, non-degradable, generated by a widely distributed polluting activity. In this case even the dilution of the aquifer capacity may not be effective to mitigate the pollution. * Additionally those aquifers that would be considered as less vulnerability to pollution, in general terms, tend to be more difficult to rehabilitate a contaminated time. In this sense, at least, they could be considered of high vulnerability to contamination. The components of vulnerability, mentioned above, are not directly measurable, but determined by various combinations of other factors. Taking into account that the selection of these parameters is based on those data probably available and easily collected, then the list is composed of: (a) the depth of the phreatic or roof of the confined aquifer.
(b) the type of occurrence of groundwater. (c) the characteristics, in terms of lithology and degree of consolidation strata above the saturated zone. These three parameters contain, even if it is in a qualitative sense, most of the required data. In the base to them applies an empirical methodology for the assessment of the vulnerability of aquifer that involves the indexation of these parameters in three discrete phases.
There are many ways to train your dog, but it is necessary to try to understand how the dog thinks and why. In order to train your dog successfully you must count on the support of all the family, since you only have molestarte yet the difficult work and sera but. Next I present/display some ideas different to begin to train your dog. You must decide which is the paper that your dog is going to take in your life and what parts of the house is going away to allow to him to enter. Your dog needs to know where it is going to sleep and in what. If your dog is going to sleep in the kitchen inside of a cage or a basket, sees costrumbrando it to that when you put in a cage or a basket it is hour to sleep.
A dog will feel like more insurances if it knows that is its place to sleep. To the dog it likes the routine and it will be accustomed to which comes if it is food, strolls or to go to the bed. You need to establish a routine around your family and your dog must know that it is in your family. A routine will take time to establish and you must be persistent and patient. Your dog needs that you teach to him where to go bathroom, where to sleep and so on. Once you have taught to your dog this, it needs to always remember the same, therefore it thinks this before obtaining its house. The dogs need consistency in their lives to make a good mascot.
Asegrate of which your family knows that she is due to allow the dog and that no. You must be patient and constant so that this works well and so that your dog can understand. You must understand the origin the dogs, like the race, the age of the dog, where the dog came and if it came from a family either trained or no. Following what type of race is the dog, sometimes is the more easy or the more difficult to train. It is always easier to train to a young dog instead of an old dog the least dogs already have some bad habits and more time is needed to train them. Although with a little perseverancia you can train it again, is only needed much more time.
