Indigenous bacterial communities are essential for biofiltration processes in drinking water
treatment systems. In this study, we examined the microbial community composition and …

The use of groundwater as a carrier of thermal energy is an important source of sustainable
heating and cooling. However, the effects of thermal use on geochemical and biological …

Populations of bacteria in biofilms from different sites of a drinking water production system
were analysed. Polymerase chain reaction (PCR) and denaturing gradient gel …

To simulate the filtration and/or degradation of trickling sewage from leaky sewers through
the non-water-saturated underground, sewage was trickled through sand of 0.4–2mm from …

Water flowing through hyporheic river sediments or artificial recharge facilities promotes the
development of microbial communities with sediment depth. We performed an 83-day …

Many water providers monitor adenosine triphosphate (ATP) as an indicator of biological
acclimation of their biofilters; however, strong correlations between ATP concentration and …

Subsurface microorganisms are essential constituents of the soil purification processes
associated with groundwater quality. In particular, soil enzyme activity determines the …

The physiochemical and functional diversity of soil-attached microorganisms was
investigated using a stabilized laboratory-scale soil aquifer treatment (SAT) system. In this …

The removal of contaminants in slow sand filters occurs mainly in the colmation layer or
schmutzdecke-a biologically active layer consisting of algae, bacteria, diatoms and …

This study evaluated the removal of natural organic matter (NOM) and structural changes in
the microbial community during infiltration of humic lake water at three artificial groundwater …
