    What do you do with completed tests

    Just curious what everyone does with their completed tests - I mean, these reagents have all kinds of hazard warnings and so on, so how do you dispose of yours?

    Interesting question. I don't have a technical response to it, but I can tell you what I do. I flush the contents of the titrant/reagent down the drain with cold water and then place the plastic bottle in the recycling bin. I wouldn't do this if I had voluminous quantities left over (say, more than 100 mL) but tap water will dilute anything I've seen in a residential test kit.

    Treatment chemicals are another matter. I toss old liquid chlorine into the pool. Haven't needed to toss anything else -- but if I did I'd probably take to hazardous waste station.

    Re: What do you do with completed tests

    I think the quantities of test chemicals are small enough that they won't be a practical problem if you dump them down the sink. They're not THAT hazardous.

    There's a brown patch of grass that my wife blames on me dumping test chemicals, which I'm not inclined to believe but not willing to argue about, either.

    I rinse my test vessel with water and pour it down the sink. Never gave it a second's thought .

    Re: What do you do with completed tests

    I agree, Paul, but I found a somewhat different solution, pun intended. My wife is also dubious about my dumping the "chemicals" in the yard.

    My wife complains that my beloved dog Spot always pees in the same place by the back steps and says that it's killed the grass in a 6-inch diameter circle. This is true.

    About once a month or so the container that I put the used reagents (and the rinse water) into is surreptitously dumped on to the same "spot".

    So until I get caught I don't have to worry about being accused of killing the grass.

    Get a dog, train her carefully, and there won't be anything to argue about!

    True story, but just for fun ... Cheers, Gary

    Re: What do you do with completed tests

    I do my testing in the field (i.e. poolside/ not at my house)

    I carry a ~2Qt, container and dump the tested samples into it. After I'm done with all the tests, I dip the container into the pool, to further dilute the sampled water (without letting the mix I've made enter the pool ) and dump that dilute mix at the edge of the lawn - i.e. at the treeline or in a drianline.

    The amount of chemicals in there isn't large and would probably be fine to dump almost anywhere, but I'm just cautious like that

    Of course Gary has a better/ safer place for that 'waste' water (Hi Gary )

    Re: What do you do with completed tests

    I usually dump it back into the pool. Or I drink it (just kidding )

    BTW

    Most of the time I'm just doing a OTO and PH test.

    Best use of the word surreptitiously I've seen in a long, long time.

    Now, Gary, what's your wife's name and cell phone number... I'd like to have her take on this! heh heh

    The area code is 666, but I don't remember the rest.

    And before you all start in on me, that was a JOKE! No way you're getting the real number.

    P.S. Love that avatar, polyvue. I have a woefully neglected Celestron that pre-dates Hubble by way too many years.
