MICROBIOLOGICAL AND MOLECULAR ANALYSIS FOR UNDERSTANDING PHENOMENA IN AN ABANDONED WATER WELL
Journal Title: Biuletyn Państwowego Instytutu Geologicznego - Year 2013, Vol 456, Issue 456
Abstract
Geomicrobiological studies were performed in the abandoned water well which still function in the national groundwater monitoring network. Extensive biofouling of cases and screens, as well as microbial mat, which completely fill-up the well at the depth of about 100 m, have been found. The microbiological analysis documented abundant microorganisms in water, while the molecular analysis of microbial mat revealed the coexistence of sulphate reducing and iron-sulphur cycle bacteria. The presence of such developed microbiological communities might indicate organic matter and SO[sub]4[/sub][sup]2- [/sup]and Fe[sup]2+[/sup] ions supply necessary for the growth of microorganisms found in the mat, which in turn would significantly affect the water chemistry.
