Have had the same thing happen to me. NOT SURE WHY YOU ARE ONLY NOTICING ON COLD TAP..... However, from my research the other posters are correct. It is from Sulfur. It happens usually if the lines that the stagnant water sit in get hot. Big issue in southern Louisiana on well water. Chlorine kills the bacteria hence no issue on city supplied water system. It is not harmful I am told. Normal flushing can rid the bacteria in the lines for the most part but you can do a sanitizing. It will come back if you are on well water. The bacteria are in the water. I usually drain the tank and lines when in storage and flush for a few minutes prior to going out - no issues.
Hope this helps
