Resumen

The research was carried out to determine the probable concentrations of heavy metals and coliforms, in the water-soil-plant system of the Rye Grass crop, caused by the wastewater of the city of Cajamarca to the water bodies in the hamlets of La Victoria, Yanamarca and La Collpa, physical analyses were carried out, (pH, Electrical conductivity, Total solids, Temperature, Turbidity), chemical (Copper, Chromium, Aluminum, Zinc, Iron, Nitrates, Sulfates, Nitrites), Microbiological (Total and thermotolerant coliforms). In the soil system, phosphorus, potassium, organic matter, aluminum and texture analyses were carried out, in the plant system total and thermotolerant coliforms were analyzed, in the water bodies system physical, chemical and biological analyses were carried out, physical parameters of the water evaluated give us results located within the maximum permissible limits established for the country; the chemical results of the water indicate that concentrations of: Iron, Copper and nitrites exceed the LMP, with concentrations of: 2.6 mg/l, in the soil system the results obtained from P, K, MO were above the average levels for the Cajamarca valley, the microbiological results of the concentrations of total and thermotolerant coliforms exceeded the LMP at all the points sampled both in the bodies of water and plants.
