The agricultural activity in the region is of great relevance at the national level, which also generates high volumes of organic waste (solid and liquid), which in many cases are not handled properly causing serious environmental damage. This paper presents advances in the determination of the contamination of the surface waters of the 20 municipalities that make up the Jalisco Highlands region, making comparisons with available information for the years 2014 and 2016, physicochemical parameters such as: Dissolved Oxygen, Specific Conductivity, Salinity,
