Match the following aspects of Guidelines for drinking water with their descriptions according to the WHO?

Radiological Aspects = The effects of radiation exposure are called “SOMATIC” if they become manifest in the exposed individual Organic constituents = PAH (Polynuclear Aromatic Hydrocarbons), and Pesticides Chemical Aspect = Inorganic constituents, and Organic constituents Bacteriological Indicators = Coliform organism, Faecal Streptococci, and Clostridium perfringes Signup and view all the answers

Match the following factors with their relevance in Bacteriological Indicators:

Faecal Streptococci = Occur regularly in faeces but in smaller number than E.coli Their presence in water indicate confirmatory evidence of recent feacal contamination Coliform organism = Include all aerobic and facultative anaerobic, gram negative, non-sporing, motile and non-motile Clostridium perfringes = Their spores resist chlorination at doses normally used. Presence of their spore indicate faecal contamination and this indicates deficiency in filtration practice Coliform organism = Both faecal and non-faecal are included Signup and view all the answers
