Environmental degradation has increased, mainly as a result of anthropogenic effects arising from population, industrial and agricultural growth. Water pollution is a problem that affects health, safety and welfare of the whole biota which shares the same environment. In Goiânia and metropolitan region, the main water body is the Meia Ponte River that is used for the abstraction of water, disposal of treated wastewater and effluents. In addition, this river receives wastewater from urban and rural areas. The aim in this present study was to evaluate the quality of raw water by some physical, chemical and toxicological tests. The physicochemical results found high levels of turbidity, conductivity, aluminum, phosphorus and metal iron, manganese, copper and lithium when compared to the standards of the Brazilian legislation. The values found of toxicity demonstrated a high degree of cytotoxicity and genotoxicity. Therefore, it was concluded that the Meia Ponte River has been undergoing constant environmental degradation, causing the poor quality of its waters. Thus, measures for the prevention and recovery should be adopted for the maintenance of the Meia Ponte River.
环境恶化加剧，主要是由于人口、工业和农业增长所导致的人为影响。水污染是一个影响整个生物群健康、安全和福利的问题，因为它们共享相同的环境。在戈亚尼亚和大都市区，主要的水体是米阿蓬特河，用于取水、处理废水和污水的排放。此外，这条河还接收来自城乡地区的废水。本研究旨在通过一些物理、化学和毒理学测试来评估原水的质量。理化结果发现，浊度、电导率、铝、磷和金属铁、锰、铜和锂的含量都高于巴西法规的标准。毒性测试的结果表明具有高度的细胞毒性和遗传毒性。因此，可以得出结论，米阿蓬特河一直在经历持续的环境恶化，导致其水质较差。因此，应该采取预防和恢复措施，以维护米阿蓬特河。
