Source and category
Where the water came from and whether it is clean, gray or contaminated.
Quick Answer
It tells you the source and category of the water, how far moisture has spread, which materials are affected and which can be dried in place versus replaced. That information lets you plan drying, repairs and any insurance discussions.
A good assessment is organized and written down.

A sequence for drying, repair and restoration.
Water damage is usually described by the source and category of water. Clean-water sources, such as a broken supply line, are different from gray water, such as washing machine or dishwasher discharge, and from black water, such as sewage or floodwater. Contaminated water requires more cautious handling and removal of porous materials.
Timing matters. The EPA advises drying wet materials within 24 to 48 hours to limit mold growth. If materials have been wet longer, an assessment can help decide whether they can still be saved.
