Abstract

Due to contamination of water sources, maximum allowed concentration levels have been established for each individual use of water, in order to guarantee their quality (drinking water, waters for irrigation, livestock, recreation among others). Brazil has established chemical water quality criteria only for drinking water (potability). Irrigation represents one of the most important uses of water in Brazilian territory. This study presents the methodology used for calculation of water quality criteria and the main difficulties in their establishment. It was verified that irrigation water quality criteria are based on phytotoxicity data, do not depend on water origin, and the differences observed for the various regulations can be explained by differences in irrigation rates and plant species considered. The choice of plant species and chemicals that should be included in the regulations depends on their regional importance, which confirms the need of establishment of proper irrigation water quality criteria for each country.
