The restoration technologies in areas degraded by extractive activities are more efficient under the use of their own spoils. Reducing deficiencies in physical properties, organic matter, and nutrients with a contribution of treated sewage sludge is proposed. This experiment was based on a controlled study using columns. The work was done with two limestone quarry spoils, both very rich in calcite. Two biosolids doses were undertaken (30,000 and 90,000 kg/ha of sewage sludge) in addition to a different quarry spoils used as substrates. The water contribution was provided by a device simulating short duration rain. The leached water was collected 24 hours after the last application. Nitrate, ammonium, phosphate, sulfate, and chloride ions were determined, as well as the pH and electrical conductivity. The electrical conductivity limit value is <1000 µS/cm. These values will be met from the fourth irrigation application onward, while the values up to that point were far superior. Significant nitrate concentrations appeared that may pose an environmental contamination risk. A comparison between the concentrations of the chemical elements obtained in the leachates from our experiment and the established limit values for water of the third quality group has been performed. The electrical conductivity correlated well with the cations, with the exception of potassium. For sulfates, significant correlations were obtained with the Mg 2+ , Ca 2+ , and K + cations. The chlorides showed excellent correlation with the sodium.
