found some standing water in basement, assume it came from storm a few days back. Running a dehumidfier didnt really dry it out over past day so got in there with wetvac today and have a fan blowing over it too. It looks like the water is "oily" and it actually beads up on the concrete floor like quicksilver. It appears that the water got into a bag of ice melt (calcium chloride). Would ice melt cause this behavior in the water???
trying to figure out if i need to find another explanations.
