There is no such thing as pure water, when you buy bottled water you think you're buying pure water but it's the same water.
I'm not going into the scientific facts here but the truth is 'pure' water does not exist because that means the water will have NOTHING in it which means they will have to remove the natural minerals and then the water will interact with any organic materials the water encounters, including air and plastic.
<em>But the water is clean and healthy to drink. Just not pure.</em>

Answer:
The result is a Positive Oxidase test
Explanation:
The oxidase test is used to identify bacteria that produce cytochrome c oxidase, an enzyme of the bacterial electron transport chain. (note: All bacteria that are oxidase positive are aerobic, and can use oxygen as a terminal electron acceptor in respiration. This does NOT mean that they are strict aerobes.
The reagent is a dark-blue to maroon color when oxidized, and colorless when reduced. Oxidase-positive bacteria possess cytochrome oxidase or indophenol oxidase (an iron-containing hemoprotein). These both catalyze the transport of electrons from donor compounds (NADH) to electron acceptors (usually oxygen).
