Yes, smelling sewer gas is unhealthy because it contains toxic compounds like hydrogen sulfide (rotten egg smell) and methane, which can cause headaches, dizziness, nausea, eye/throat irritation, and fatigue at low levels, while high concentrations can lead to unconsciousness, organ damage, and even death, plus fire/explosion risks. While occasional faint smells in well-ventilated areas might be minor, a persistent sewer odor indicates a dangerous leak requiring immediate attention from a plumber.
The health risks linked to sewer gas exposure include: Hydrogen sulfide poisoning: Hydrogen sulfide smells like rotten eggs, even in low concentrations. Exposure to low levels of hydrogen sulfide can cause eye and respiratory irritation.
Yes, a sewer gas leak in your home can cause a host of issues, including eye irritation, coughing, wheezing, nausea, vomiting, migraines, drowsiness, and even loss of consciousness.
A sewage smell in your house is always a problem, not just because it's gross but because it means there's a problem with your home's plumbing. Sewage smells, of course, sometimes indicate the presence of sewage itself.
Direct contact with sewage or surfaces contaminated by sewage can result in illnesses such as gastroenteritis. Wear protective clothing (such as rubber gloves, boots and eye protection) when cleaning. Do not use your water supply until you know it is safe.
5 Devastating Health Risks of Sewage Spills: Why Immediate Cleanup Is Crucial
Sewage contains germs like bacteria and viruses as well as parasites and worms that can cause stomach and intestine or liver illness. Germs and parasites may cause diarrhea, fever, cramps, nausea, vomiting, headache, weakness or loss of appetite.
Regularly clean your drains using a mixture of baking soda and vinegar or a cleaning solution recommended by a professional. Flush the drains with hot water to help remove any residual odor-causing substances. Ventilate Your Home: Adequate ventilation can reduce the concentration of sewer gas in your home.
Any unusual smell inside a building — especially a sewer-like smell — should be taken seriously. A sewer gas smell is often a sign of plumbing issues, like a sewage backup in the basement or damaged drains.
7 Signs You Have a Problem with Your Main Sewer Line
You might feel lightheaded. Nausea: the smell of sewer gas can even cause enough discomfort to make you feel uneasy and may cause you to throw up. Headaches: mild to intense headaches may occur if you are breathing sewer gas in for a period of time and not realizing it.
If you smell sewer gas in your home, it's important to address the issue promptly for health and safety reasons. You should contact a licensed plumber to inspect your plumbing system and identify the source of the odor.
Exposure to low levels of this chemical can irritate the eyes, cause a cough or sore throat, shortness of breath, and fluid accumulation in the lungs. Prolonged low-level exposure may cause fatigue, pneumonia, loss of appetite, headaches, irritability, poor memory, and dizziness.
Symptoms typically develop 4 to 7 days after exposure and may last 1 to 3 weeks or longer. Most infections are uncomplicated and resolve completely. In a few cases the bacteria can spread to the bloodstream.
If the smell is coming from a neighbour or local business, contact your local council.
Exposure to sewer gas can be dangerous, and can lead to eye irritation and respiratory issues like a sore throat and cough for all residents—including your pets. You don't have to evacuate the premises, but maybe slide open a window or step away from the smell while you plan out your next steps.
The hardest smells to get rid of are often deeply embedded, like skunk spray, cigarette smoke, pet urine, mold/mildew, and fire/water damage odors, because they permeate porous materials (carpets, upholstery, drywall, synthetic fabrics) and can get into HVAC systems, requiring professional cleaning or specialized ozone treatments to neutralize the odor molecules themselves, not just mask them.
If a plumbing fixture isn't used for a week or two, its P-trap can eventually dry out due to the water evaporating. In this case, all you need to do is run water down the drain for a few seconds to refill the trap, and the sewer smell should then dissipate fairly quickly.
Yes, extended exposure to sewer gases can be harmful, particularly when gases like methane or hydrogen sulfide are present in high concentrations. These substances may cause symptoms such as dizziness, headaches, nausea, and respiratory problems.
Gastrointestinal Illnesses: Bacteria such as E. coli, salmonella, Shigella, and viruses like norovirus and rotavirus can cause severe diarrhoea, vomiting, fever, and abdominal cramps. Hepatitis A: A highly contagious liver infection that can be transmitted through contaminated faecal matter.
Sewage pollution is a vector for disease and exposes human populations and wildlife to health risks. These include gastrointestinal illnesses, skin infections, and a wide range of potentially life-threatening conditions like hepatitis A and E, salmonella, E. coli, dysentery, typhoid, and cholera.
Chronic exposure to low-level sewer gases can cause persistent health problems including respiratory irritation, neurological symptoms, and increased susceptibility to respiratory infections. Children and elderly residents face particular risks from even brief exposure periods.
Sewage bacteria can survive on surfaces for: Porous surfaces (wood, carpet): up to several months if not properly cleaned. Non-porous surfaces (tile, metal): several days to weeks. Damp environments: much longer than in dry conditions.
Germs and parasites may cause diarrhea, fever, cramps, nausea, vomiting, headache, weakness, or loss of appetite. Hepatitis A can cause liver disease; symptoms may include feeling tired, having pale poop, and having yellow eyes and skin.
A single small exposure from which a person recovers quickly is not likely to cause delayed or long-term effects. Moderate exposure can cause residual damage and a serious exposure that causes coma or convulsions may damage the brain and heart.
