    The objective of this study was to establish the quality of water for human consumption by analyzing the results of studies on physicochemical and microbiological parameters, using a systematic review complemented by a meta-analysis. The use of these techniques established that the scientific production at the university academic level is of low quality. A synthesis of results based on the standardized mean difference between the values found for each analyzed parameter and its corresponding standard allowed the study to establish that not all of the required tests for mandatory control parameters were performed. A standardized mean of 0.04 (95% CI: -0.15 to 0.22) was found for pH, and 0.11 (95% CI: -0.9 to 0.32) was found for free chlorine content. Both values showed a tendency toward the standard but were not statistically significant. This indicates that the analyzed studies do not provide robust information to draw conclusions about the quality of the water consumed in Lima.
