Flooded basement. Wet carpet and pad. WTF? Over

I accidentally pulled my dehumidifier's drain hose out of the wall drain... And water ran onto the floor for about a week, wetting some of the carpet and padding in an adjacent room and hall.

Soon as we realized this we rented a commercial dehumidifier + carpet fan from HD and sucked the space dry for 48 hours. Pulled a LOT of water out but I left everything in place.

Fearing mold, I asked the original carpet installer how much to replace the pad and re-stretch the carpet (assuming I pull it up and disinfect the slab, old pad goes in a dumpster). They said $500. 

So... who has lived this life before me? How berkeleyed am I?

Is there any chance I don't have mold under there if it was wet for a week?

Thanks

Pull it, and get rid of the padding. It is nearly impossible to get it dry enough without Serve-pro or somebody like that running a bunch of blowers for about 4 days. It cheaper to go the route you have a quote for.

In reply to jgrewe :

Thanks for the reply. 

Additional context: I'm running my original dehumidifier now but using the bucket (rather than the hose into a drain) so that I can have it located closer to the area that got wet.

It's still pulling a lot of water but since the unit normally runs into a drain I have no clue  how much water it normally draws out of the space.

It's a science project that I regret having brought upon myself.

I also wonder how much moisture (thus mold) there was under the pad before I went and got it all wet...

Next question: buy high dollar disinfect or paint the slab with kilz or something?

You definitely have the environment for mold down there now.  BTDT.

I installed ceramic tile in my basement after the carpet fiasco.  An area rug can be moved as needed.

You should've pulled the carpet and pad immediately. 

In the future, skip the pad in the basement. makes cleanup a heck of alot easier. 

The carpet and pad need to be ripped out.  No recovery from this.  Just mold.

Serve Pro "dehumidified" an acquaintances' house after the Houston Harvey flood.   I told  him it would take two months for the A/C  to suck all the water out of the wooden frame and slab before he should put sheet rock up.     What do I know, I'm just a Professional Engineer?

Any way he put up the sheetrock and finished the interior in record time.   A few months later he was getting it all ripped out because of black mold growing on his walls.    I had no comment, no use piling onto his misery.

I ran my A/C at 60 deg F and some small dehumidifiers for two months and had no such problems...  My point being it takes a long time to dry out flooded areas of absorbent materials that have had any amount of soak time.   And carpet is already full of dry mold spores just waiting for some moisture to activate them.
