Huntington Beach, California, June 12, 2026
Indoor water damage can lead to far more than ruined building materials, furniture, and personal belongings. In severe cases, it may compromise a structure’s integrity and create hazardous indoor conditions that put building occupants at risk.
The potential health risks depend largely on the source of the water. Water intrusion can introduce bacteria, viruses, mold, chemicals, and other contaminants into an indoor environment. Even damage caused by clean water, referred to as Category 1 Water, can support mold growth within as little as 24 to 48 hours if materials are not dried promptly.
Category 2 Water, commonly known as Grey Water, contains biological or physical contaminants that may cause illness through exposure or accidental ingestion. Typical sources include sump pump failures, dishwasher overflows, and washing machine discharges. If Category 2 Water is not quickly removed or becomes stagnant, it can deteriorate and be reclassified as Category 3 Water.
Category 3 Water, also called Black Water, is heavily contaminated and may contain dangerous pathogens, microbes, and chemicals capable of causing serious illness. Common sources include sewage backups, seawater, flooding from rivers or streams, ground surface water, and long-standing stagnant water.
“Mold is often the first concern people think of when water damage occurs, but it’s far from the only exposure risk,” said Michael Chapman, Laboratory Manager of LA Testing’s Huntington Beach facility. “Sewage, bacteria, and chemical contaminants can also pose significant health concerns. In addition, the drying and restoration process itself may disturb materials already present in a building, such as asbestos-containing materials or lead-based paints. If not properly managed, these materials can become airborne during cleanup, drying, or rebuilding activities. Air movement during drying can also spread contaminants into areas that were not originally affected by the water damage.”
