Sewage cleanup involves removing and disinfecting raw or partially treated sewage overflow. Untreated sewage contains harmful bacteria, viruses, and parasites that can cause severe illnesses if ingested, inhaled, or come into contact with open wounds. ## Cleanup and Disinfection Sewage cleanup professionals use specialized equipment to extract the sewage from the affected area. They then disinfect the area using EPA-approved cleaning solutions to eliminate harmful microorganisms. This process may involve multiple applications of disinfectant and thorough rinsing. ## Effects of Sewage Contamination Sewage contamination can have serious health consequences: * **Gastrointestinal illnesses:** Ingesting sewage-contaminated water or food can cause diarrhea, vomiting, stomach cramps, and nausea. * **Skin infections:** Contact with sewage can lead to skin rashes, boils, and other infections. * **Respiratory problems:** Inhaling sewage fumes can cause respiratory irritation, coughing, and difficulty breathing. * **Long-term health effects:** Repeated exposure to sewage contamination can increase the risk of developing chronic conditions, such as asthma or liver damage. ## How Long Does Sewage Contamination Last? The duration of sewage contamination depends on several factors, including: * **Temperature:** Warm temperatures accelerate the growth of bacteria. * **Sunlight:** UV rays can disinfect sewage, but only if it is exposed to sunlight for extended periods. * **Type of sewage:** Raw sewage contains more pathogens than partially treated sewage. * **Amount of contamination:** Larger spills take longer to clean up and disinfect. In general, sewage contamination can remain active for several hours to days in ideal conditions. However, it can persist for weeks or even months in cold, dark environments with limited exposure to sunlight. Professional sewage cleanup services are crucial for ensuring the complete removal and disinfection of sewage contamination, minimizing the health risks associated with exposure.
