Soil contamination from the use of wastewater

Abstract

The contamination of soils by the use of wastewater in the valleys of the San Mateo, Colpa Mayo, San Juan and Río Chotano streams, arose from the need to demonstrate that the soils that use wastewater to irrigate crops are contaminated, the investigation had The main objective: to demonstrate the index of soil contamination by the use of wastewater, the investigation was of an experimental type that consisted of collecting 5 samples of cultivated land with the purpose of verifying the potential of Hydrogen (pH), Conductivity Electrical (C. E.), Phosphorus (P), Potassium (K), Carbon (C), Organic Matter, Nitrogen (N), mechanical analysis, Cation Exchange Capacity (CEC), amount of Calcium (), Magnesium (, Potassium (), concentration of Sodium () and Calcium Hydride (), the relevant results highlight that most of the samples present overlapping concentrations of chemical components, to those proposed by the Organization of the Nac United Nations for Food and Agriculture (FAO, 2013). Based on the data, it is concluded that the excess pH found in the soils makes it alkaline, the excess of phosphorus, potassium, carbon, organic matter and the regularity of nitrogen mean that the soils do not perform their normal functions in the cultivation of the plants and that the milliequivalent values per 100/g exceed the limits allowed by current regulations.
