【Characterization of Biofilms and Mineralogical Scale in Underground Injection Well Disposal of Landfill Leachate and Industrial Wastewater Streams】

Fouling of #injection_wells can lead to catastrophic failure of the industrial wastewater collection and disposal system. Fouling can take the form of biofilms, mineral scale deposits, or both. In this paper, biofilm and mineral scale samples from three depth intervals within a deep injection well (surface zone, D1= 0 - 61 m; intermediate zone, D2 = 62 - 457 m; and above the injection zone, D3 = 458 - 884 m) with recurrent biofilm development were collected to characterize the mineral composition and microbial community DNA. Microbiological analysis will provide useful information about the sub-surface microbiota in the injection well whereas mineralogical analysis along with water quality parameters will provide insight relating to the scaling potential as well as the chemical composition of the biofilm. #Biofilm_Microbiology #Well_Rehabilitation
