[AT] OT: chemical containers Ron Cook and others

[Herb Metz]

We have five such tanks catching rain water from one side of our shed and 
two such tanks catching rain water from west side of our home. Have done 
similar projects on five tanks for gardening friends.  Several tanks had 
"release" for spraying plywood forms before pouring concrete, so forms could 
be removed from setup concrete without destroying forms, another had a 
powder used around operations involving much cutting of paper (keep dust 
down), couple more had sat long enough that chemicals in bottom had 
evaporated and dried; physically removed residue with mop on end of long 2" 
x 2" after no luck with gasoline, and several other chemical liquids.  Above 
tanks had large, professional labels secured to side; I had no way of 
knowing if this label applied to the last time this tank was used, however 
the tanks were in good condition but may have been a bit optomistic in 
concluding most had been used just one time.
Thank goodness I finally wised up and passed if tanks contained any liquid. 
Scrubbed all tanks with soapy, hot water. We  were the only customers with 
vegetable garden. Last tank was installed in 2008.
This certainly does not answer your question or concern. That uncertainty is 
one reason I did not pursue this project any further; the other reason is 
although customers were happy, I was only making a couple bucks/hr.
Water rates in our area are high because Lake Lanier is principal source; 
and watershed area feeding Lake Lanier is vary small, and AL, FL and GA have 
been in political niff-naff over water rights for couple decades.
IF YOU do such project, suggest replacing aluminum downspout with plastic 
pipe with glued joints and feed water into tank through the 2" hand valve at 
bottom side of tank and extend the same pipe so hose bib can be installed. 
Looks neater, can leave cap (loose) on top of tank, and no mosquitos.

Ron or anyone else that might know.
I have acquired a couple of 275 gallon plastic "carboy"
type chemical containers.   There is a slight amount of
chemical in the bottom of them and I don't know what it
is.   I've noticed that both containers have a RED lid
on the top of the tank.  I'm wondering if that RED lid means
something or if that is just the color the manufacturer
decided to use?
Anyone have an idea?
I don't intend to use them for anything other than NON-potable
water storage for pressure washing but I need to know that I've
properly cleaned them.
