Abstract

This study addresses the pressing need for effective, in-situ bioremediation of irrigation water contaminated with microbial pathogens. Contaminated water can introduce pathogens to crops, impacting both agricultural productivity and public health. Using organo-minerals as a treatment method, we specifically focused on microbial reduction by measuring the presence of Escherichia coli and Salmonella spp. before and after treatment. Quantitative analysis showed a significant decrease in microbial contaminants post-treatment, with microbial levels reduced by an average of 70% across sampling sites. Statistical analysis using ANOVA and post-hoc Tukey tests confirmed that these reductions were statistically significant, with p-values < 0.05. The study highlights the potential of organo-minerals to improve water quality parameters, supporting both crop safety and sustainable agriculture.
