Abstract
This study evaluated the seasonal variability of water quality in the Tilacancha River, the water source that supplies Chachapoyas, and the rural communities of Levanto and San Isidro del Maino of Perú. Eighteen physical, chemical, and microbiological water parameters were evaluated at five sampling points in two seasons (rainy and dry). To determine water quality, the results obtained for the parameters evaluated were compared with the Maximum Permissible Limits (MPL) established in the Regulation on Water Quality for Human Consumption (DS Nº 031-2010-SA), approved by the Environmental Health Directorate of the Ministry of Health. In addition, a Pearson correlation was performed to estimate the correlation between the variables evaluated. The results showed that microbiological parameters exceeded the MPLs in both periods evaluated, such as the case of total coliforms (44 MPN.100 mL-1), fecal coliforms (25 MPN.100 mL-1), and E. coli (5.45 MPN.100 mL-1), these microbiological parameters reported a positive correlation with turbidity, temperature, total dissolved solids, and flow rate. In addition, aluminum (Al) and manganese (Mn) exceeded the MPL in the rainy (0.26 mg Al.L-1) and dry (1.41 mg.Mn-1.L-1) seasons, respectively. The results indicated that the water of the Tilacancha River is not suitable for human consumption. Therefore, it must be treated in drinking water treatment plants to be used as drinking water.
期刊介绍：
The journal was established initially by the name of Journal of Environment and Pollution in 1994, whose name was later changed to Nature Environment and Pollution Technology in the year 2002. It has now become an open access online journal from the year 2017 with ISSN: 2395-3454 (Online). The journal was established especially to promote the cause for environment and to cater the need for rapid dissemination of the vast scientific and technological data generated in this field. It is a part of many reputed international indexing and abstracting agencies. The Journal has evoked a highly encouraging response among the researchers, scientists and technocrats. It has a reputed International Editorial Board and publishes peer reviewed papers. The Journal has also been approved by UGC (India). The journal publishes both original research and review papers. The ideology and scope of the Journal includes the following. -Monitoring, control and management of air, water, soil and noise pollution -Solid waste management -Industrial hygiene and occupational health -Biomedical aspects of pollution -Toxicological studies -Radioactive pollution and radiation effects -Wastewater treatment and recycling etc. -Environmental modelling -Biodiversity and conservation -Dynamics and behaviour of chemicals in environment -Natural resources, wildlife, forests and wetlands etc. -Environmental laws and legal aspects -Environmental economics -Any other topic related to environment
