Hydrogeochemistry and microbial diversity assessment of anthropogenic activities on a suburban ecosystem within Ibadan, SW Nigeria.

. Similarly, safe levels were observed for the anion concentrations. Hydrogeochemical facies suggest predominantly calcium-bicarbonate and alkali/alkaline earth-chloride water types while the water quality index indicated generally good to excellent quality, with one sample located south of the market classified as fair. Microbial diversity and enumeration showed relatively high bacterial and fungal densities in waste-impacted soils. The coexistence of decomposer taxa, faecal indicators, and opportunistic pathogens may reflect localised ecological stress associated with anthropogenic activities.
