I use the car no start method to detect water in fuel.

Draw the fuel to be USED from NOT the bottom of the tank, eg. put the standpipe several cm above the bottom, or pour off the top in jerry cans. If 44s must be upright to be used, eg. intermittent refuelling, tilt them a few degrees, so the water runs to the corner, away from the pump's pipe.
TESTING:
Get a TEST SAMPLE from the BOTTOM of the tank/drum or filter drain. Put into clear container, eg. glass jar. Eye ball test only works if obvious drops of water, as colour can be the same. Add some oil from the dipstick...it sinks in fuel, floats on water. In some (petrol) engines, Jack Absolom used to say add a cup of metho to the tank when fuelling from drums, as it mixes with the water like E10 fuel and just burns in the carby....not sure about diesel. Keep tanks full, as condensation is a big source of water in fuel. Thought: copper sulfate is white, unless wet with water: can this turn white in "dry" fuel? Some homework for bored people this weekend.

I wasn't thinking of trying to get the paste down through the filler tube to check a vehicle tank! More dipping the 1000+ litre tanks on farms. Or 44s like bushdoc2 says. Some of these have had fuel in them for decades so there may be a fair bit of condensation water in the bottom by now. Not sure, maybe it boils off in summer? I regularly run vehicle tanks dry to keep them clean(er). I am a bit of a fusspot with fuel, cleaning fuel systems and bleeding diesels sucks, so I would rather not have to do it. Although if you have a diesel and it isn't self-bleeding you should probably practice bleeding it. And if you don't know what I'm talking about and do have a diesel it would be to your advantage to find out or you may end up stuck somewhere. I have added a splash of metho to petrol tanks for years. Doesn't seem to hurt, although thinking about it I probably don't need to when using E10! Will have to check if the alcohol in E10 absorbs water.

A number of years ago I was given almost 2 dozen or so 10 to 20 liter gas containers... Some steel, most plastic, also 4-5 outboard motor tanks..
All had some gas in them.. I poured it all together into several 20 l containers, tinted it a very light blue with some old 2 stroke oil and let it settle.. I then siphoned it off into clear 4 l containers to let it settle again, then siphon into a container to use out of..
I mixed it 10 to 1 with fresh fuel to use in my old Dodge pickup.. It was a slow process, but I was able to salvage about 60 l of fuel with only about 2 l of fuel that was a total loss.. Not a loss actually as it started the fire pit several times..
I threw away the containers that needed that.. Gave away containers, sold containers, with the outboard cans bringing $20 - $30 each.. === We used to call that paste "water thief" paste.. Unless you have a significant storage capacity, the paste seems quite expensive now...
