In the modern world the problem of the reliable water supply is extremely important because the water resources are widely exploited and water is used in different fields of human activities. In fact, the life of human beings is impossible without water but nowadays water is used not only simply to provide people with the essential substance they consume to survive but it is also widely used in agriculture and different industries.

On the other hand, often there is practically no other choice but to expand landfills because many communities grow, industry progresses and the quantity of wastes is constantly increasing. In such a situation, there are few alternatives to landfills expansion. This is why the primary task of the operators of such facilities is to make them really safe to the health of people living nearby. Continue reading
