our public water utility company has issued a boil water notice for our area. I have about 2 gallons of Ro/di water left and need to produce some more. I am wondering if iit safe to use the water to produce Ro/Di water for my reef tank. I have read conflicting statements if it is safe to do so. Just curious as I would hate to add contaminated water to my system. Any help would be appreciated.

My Tank Thread
It most likely needs to be boiled because of the likelihood of bacteria. They can't actually make the claim, but RO removes bacteria. So if it was me, I'd be making water right now. 
good point. im in same boat as OP. I just dont think my water pressure is high enough yet. normally 60 range but I will have to check when I get home. Well guess I would still have to wait another day or 2 for weather to get a little warmer
I do have a TDS meter so I can confirm no desolved solids. From what I have been reading is that the bacteria can still get thru, but other sites have said the RO membrane will catch it. They do state if you have a uv sterilizer it will kill the bacteria, but unfortunately I do not have one currently. I am just not sure if the bacteria does get thru is it harmful to the tank inhabitants?
I live in Texas, so most of the store are limited in supply so will assume water and distilled will be limited. My water pressure is back up to over 40 psi so should be able to make water. Did test for chlorine in the water source and none appears to be present. I am assuming I can make the ro/di water then boil it to remove any bacteria just to be safe. any thoughts on that?

I think everyone here is forgetting that the water is then being mixed with salt.
That should kill anything left.
Anything else left, you’ve already dumped it in your tank during each water change.
I probably would be drinking the water without boiling if really thirsty.
Much in the hobby once was on a cargo flight in a box bouncing around for a day or two before being opened, they will survive a touch of salmonella.
Don’t sweat the small stuff. Just keep an eye on your resin.
