quality problems. Lake Chapala is the most important water distribution centre in the region and was seriously threatened by growing biological and chemical water pollution. This generated a public outcry in the state of Jalisco and eventually became a matter of national concern. VIII.[r]

Water quality is assessed using sampling data for a defined set of physical and biological indicators using the appropriate water quality standards of the Russian Federation. It is, however, noticeable that assessments made by different agencies and institutions sometimes differ as a r[r]

In the Mediterranean basin, wastewater has been used as a source of irrigation water for centuries. In addition to providing a low cost water source, the use of treated wastewater for irrigation in agriculture combines three advantages 1) using the fertilizing properties of the[r]
