In this article we will discuss about the important microorganisms that occur in varying water habitats. The type of microbial populations differ in different type of water habitats such as unpolluted, polluted, and marine waters. Table 31.1 represents the important microorganisms occurring in varying water habitats: Microorganisms in Unpolluted Water: In unpolluted water of mountain lake or stream there are [...]
The following points highlight the top two techniques used for determining the potability of water. The techniques are: 1. Coliform-Test-Technique 2. Membrane-Filter-Technique. 1. Coliform-Test-Technique (Multiple-Tube Fermentation Test): Coliform-test-technique (or MTFT) is a standard method followed all over the world to determine whether the water is potable or faecally polluted. The technique involves three successive steps, namely, presumptive test, confirmed test, [...]
The following points highlight the top two methods used for the removal of pollutants from groundwater. The methods are: 1. Active Remediation 2. Natural Attenuation and Monitoring. Method # 1. Active Remediation: The predominant groundwater remediation strategy is the application of the so-called 'pump-and-treat' technology in which mainly physico-chemical techniques are used to remove the pollutants in-the above- ground treatment [...]
