Diagnóstico do potencial poluidor das agroindústrias familiares sobre o Rio Piancó.

Abstract

Water quality has been seriously impacted mainly caused by human actions. Because of this, the water quality is becoming a scarce commodity. This fact is compounded in the Brazilian semi-arid northeast, where water availability is quite limited because of its climatic conditions. Much of the Northeast economy is focused on the rural sector, where the agricultural industries are located. Much of the waste generated by agro-industries are eventually leached up to a water body receptor, causing the expense of quality of its waters. Faced with the above objective is through this research to evaluate the potential polluter of family farms on the Piancó river, municipality of Pombal-PB. The research was conducted from May 2014 to December 2015 in two agricultural industries, a slaughter of poultry and other cheese production, which were collected sample of the raw wastewater and Piancó river waters adjacent agro-industries and forwarded to Water Analysis Laboratory for evaluation of physical, chemical and microbiological parameters. It can be concluded that the two agribusinesses cited, despite being small, have a high pollution potential for this high organic load as well as the launch directly into the environment without any prior treatment and contaminate underground water bodies. It was also concluded that the effluent not yet directly reaches the Piancó river possibly caused by severe drought hitting the region. However, in rainy periods, rises the chances of this pollutant to be leached into the river. Thus, it is necessary training activities and awareness of producers and employees of agricultural industries in order to optimize water usage and promote viable treatment systems, as well as the possible reuse of these effluents.
