    There are various sensors which can be used to detect the presence of some contamination, these can be substrate types with particular chemical sensors, or can be laser like. It really depends on the type of toxin you are talking about, but most, if not all can be detected, these are sampled for on a regular basis.

    Had you any particular toxin in mind?

    Yep there is one for that, and there is even a countermeasure for it funny enough, any of a varitey of toxins will produce an alarm which will shut off valves and isolate the supply, the efficiency of this depends upon where you are in the world. Other supplies can be re-routed and the customers never get to know, as of about 2002 though very little data has been published as there is thought to be a threat to the water supply from terrorists. I know of one place where a traditional reservoir is no longer used at all, but the population thinks it is! it is a decoy.

    The hand of time rested on the half-hour mark, and all along that old front line of the English there came a whistling and a crying. The men of the first wave climbed up the parapets, in tumult, darkness, and the presence of death, and having done with all pleasant things, advanced across No Man's Land to begin the Battle of the Somme. - Poet John Masefield.

    IN that particular place, the old water system has been bypassed totally, it is more a reserve job - more and more for example the UK is storing water underground, some reservoirs are also being covered!.

    That tells you about the detection method of arsenic in water.

    having said that - how many public supplys have acess to the dectors ect.

    rural areas depends on - random tests. and even then they dont exactly test for everthing.

    i suppose the fact we dont have resources is one reason why we dont need to have the measures in place - tricky

    Feel free to correct any false information, which unknown to me, may be included in my posts. (also - let this be a disclaimer)
