Physicochemical and biological tests to determine water quality in the San Luis Ayucan River, Municipality of Jilotzingo, Estado de Mexico State

Abstract

Jilotzingo is one of the 125 municipalities that make up the Estado de Mexico State, which has a wealth of flora and fauna thanks to its rivers and springs. Unfortunately, the bad practices of society damage the hydrography of the area, as part of the 2030 agenda, the priorities of Today's Society are established on various current issues such as Sustainable Development, within this agenda, Goal 6 talks about the importance of clean water and its sanitation, this work focuses on the analysis of water quality as it is essential for public health and the sustainability of aquatic ecosystems. Physicochemical and biological tests were carried out to determine critical parameters such as hardness, acidity, alkalinity, flocculation, total chlorides and microorganisms, all tests are based on Mexican Standards such as NMX-AA-072-SCFI-2001, NMX-AA - 036-SCFI-2001, NMX-AA-073-SCFI-2001 and the obtained results are compared with NOM-127-SSA1-2021 to verify the permissible limits of water quality for human use and consumption since the inhabitants they use for their daily activities.
