That depends on the contaminant.
It can smell like anything that is in it as water has no real smell.
It will either look like water or water with bits floating in it or dirty water.
For example water used in nuclear power plants is radioactively contaminated but it looks and smells like water (if a bit metallic, but so does tap water).
Bottom line if the water might be contaminated. DONT drink it.
clear liquid that kind of looks like water but does NOT smell like it!
It actually doesn't have an smell!! It has a strange look though.
Iron filings are small, fine particles of iron that resemble tiny metal shavings or grains. They are typically silvery in color and can be attracted to a magnet due to their iron content. Iron filings do not have a distinct smell.
When sugar is dissolved in water, it appears as a clear, transparent solution with no visible sugar particles.
Butanol, CH2OHC3H7, smells like glassex, 'glass-shine window cleaner' alcohol. It looks like a colorless clear fluid which it is.
The water looks dirty and it has some sort of smell eminating from it
Look and smell nice
smelled like your mom
It is probably a dead shark. I had this problem so i went under my house and found a rotting bees nest. If you have ever been to hanmer springs in new zealand, there are hot springs there which have a strong sulphuric smell. There are also thousands of bees there. While the bees do not cause the smell, they certainly make it worse. Look for any traces of bees under and around your house and spray contaminated area/s with water and sodium bicarbonate, which will neutralise the smell.
Smell and sight are completely separate senses, unless you have synesthesia.
It will smell and may have mold on it. The mold can be yellowish in color.

Look for water leakage. You might have some water damaged wood.
I think that it's appearance won't really change but I assure you it will start to smell especially if left in a humid or warm environment.
