Caracterização hidroambiental da vila de Jericoacoara, Jijoca – CE

Abstract

The small village of Jericoacoara in the last decades, due to its great international visibility from the 90s until now, has received an air of a must-see tourist route, thus increasing not only the local population, but also the infrastructure in a disorganized and unplanned way, contributing to the misuse and contamination of groundwater resources. This research presents a hydro-environmental analysis of the aquifers that supply the region, evaluating the use and the current sanitary conditions, as well as groundwater quality. The research was based on the results obtained through analysis of underground flow, water table and physical-chemical and bacteriological parameters of samples collected in the wells of the region. It was verified that 100% of the samples are in non compliance with the values allowed by Decree 2914/11 of the Ministry of Health and CONAMA resolution 396/2008, for water destined for human consumption, in at least one of the analyzed parameters. The consumption of water from the region's drilling wells poses a health risk to the population that uses water for consumption, since it does not present adequate drinking conditions and is capable of transmitting water-borne diseases, such as methemoglobinemia and diarrhea. Continuous water monitoring is advisable, aiming at preventive actions. It is also important to evaluate the physical quality of the wells, requiring correct construction in accordance with ABNT standards.
