  Unfortunately no single test or tool can detect all possible building contaminants. We use methods and equipment which can test for common contaminants. If the identity of a specific contaminant is known in advance we can also test for a very large number of specific contaminant gases in buildings. We use gas sampling equipment provided by the two most reliable companies in the world, Draeger-Safety's detector-tubes and Drager accuro� bellows pump, the Gastec� cylinder pump and detector-tube system produced by Gastec or Sensidyne, and we also use Sensidyne's Gilian air pump. For broad screening for combustibles and a number of other toxic gases and for leak tracing we also use Amprobe's Tif 8850 and TIF 8800. All of these instruments, their applications, and sensitivities (minimum detectable limits) for specific gases are described in our Gas Sampling Plan online document.

• Odors, Odor Detection, Smells, & Gases how to find and identify sources of noxious or toxic odors and gases
• Animal Smells may be due to current or prior pets in a building, pet urine or fecal waste, cat boxes, animal hair, dog dander, cat dander (are allergens and are indicators of the level of prior pet activity), dust tracked in by dogs. But animal odors in buildings can also occur when an animal such as a mouse or rat has died in a building cavity. A dead animal smell has been described by our clients with a wide variety of terms ranging from a vague noxious stink that seemed to vary with humidity to a sweet sickly smell. Dead animals or even insect nests in building plumbing, especially building vents, can also produce unexpected sewer odors - see Septic and Sewer gas odor links discused below.
• Drain Odors: Plumbing Drain Noises - Diagnosis & Repair guide. This article discusses the cause, diagnosis, and cure of plumbing drain noises. That "blub blub" or "glug glug" noise you hear from a building drain might mean that there is a problem with the drain system itself, such as a partial drain blockage, a drain venting problem, a drain odor problem, or even a failing septic system. Here we discuss the causes and cures for plumbing drain noises, and we refer to key companion articles that assist in that diagnosis.
• Gas Odors: A Toxic Gas Testing Sampling Plan for Residential Indoor Air Investigations. This document outlines gas toxicity levels and gas testing procedures we use in field IAQ and environmental health investigations for a range of indoor gases which may be produced by building product outgassing, mold and MVOCs, mechanical systems, fire damage, or contamination from nearby industrial, beauty parlor, dry cleaning, or other activities which often produce noxious or toxic odors and gases.
• Mold Odors or Smells: This website provides information and procedures for finding, testing, cleaning and preventing indoor mold, toxic black mold, green mold, testing building indoor air quality, and other sick house / sick building investigations. Here are research articles, inspection and testing procedures, and contact information for expert services. We give in-depth information about indoor air quality problems: causes of respiratory illness, asthma, or other symptoms such as neurological or psychological problems, air quality investigation methods, and remediation procedures such as mold cleanup, handling toxic mold contamination, and building or mechanical system repairs. We offer advice on mold prevention and mold-resistant construction resistant to indoor problem molds such as the Aspergillus sp., Penicillium sp. and Stachybotrys chartarum groups.
• Mold Odors: If we smell mold, is mold present and is that a problem? Most people have a pretty good idea of moldy or musty smell as associated with mold. If you smell mold or find it at important levels in screening samples of air, dust, or vacuumed surfaces, (by quantity or by particle type in samples) it is probably there.
• Mold Odors: Why do mold odors occur in my home following rain? Odors at exterior outlets sure sound as if there has been leakage into the wall and a probable mold colony. We need an expert visual inspection and possibly invasive sampling, combined with building history, to find and follow leak paths and high humidity cavities in order to inspect the most-likely mold reservoir targets in a building. The odors may be MVOC's which may be produced by some mold genera/species at varying levels as humidity, temperature, air pressure, and other variables change.
• Oil Odors: Leaky Oil Tank Piping at the oil storage tank filler or vent piping can be diagnosed and repaired
• Oil Tank Leaks and Smells are discussed at our website on handling above ground or buried heating oil storage tanks. These online articles answer most questions about above ground or buried oil storage tanks. Extensive free un-biased oil storage tank inspection and testing advice for property buyers and owners. This document lets you know what to ask about oil storage tanks, what oil tank leak tests to order, how to interpret oil tank testing results, what to do if there is a buried fuel or petroleum storage tank at a property, what to do if there is or was a leaky oil storage tank or petroleum storage tank, and how to reduce the chances of an oil leak or oil spill in the future. We include detailed information about underground (buried) oil storage tanks (USTs), aboveground oil storage tanks (ASTs), above ground fuel storage tanks, reporting and cleaning up oil tank leaks, and choosing among oil tank leak testing methods. We discuss how to find buried oil tanks, how to remove or abandon oil tanks and how to recognize evidence that there was a previous oil tank at a property even if the oil tank may have been removed (or perhaps left buried in place). We discuss what to do if an oil tank has already been removed or abandoned. We provide links to every U.S. state regulatory agency concerned with oil and other storage tanks and to regulatory agencies in Canada and other countries. Environmental damage from oil leaks, oil spill cleanup, are also discussed. We discuss oil spill cleanup, oil spill and odor remediation, and bioremediation, for fuel oil or heating oil. LP Gas tanks are also addressed. Home heating oil tank leak and environmental contamination risks are important concerns for building owners and home buyers as major cleanup and tank replacement costs can be involved.
• Ozone Odors & Ozone "deodorizers": The Use of Ozone Generators Indoors for Control of Odors and Mold Removal in Buildings: A Summary of Hazards and False Claims. Ozone is widely promoted by ozone generating equipment companies and cleaning services for use in indoor building environments to deodorize, disinfect, "kill" mold, and for "general health". Ozone generators are also promoted for use to reduce the level of airborne particles, pollen, animal dander, and allergens, ostensibly to improve indoor air quality for asthmatics and people with allergies. While there are some important uses of ozone (such as for medical disinfection under controlled conditions), in general this is an idea which ranges from bad to dangerous in the home. This article explains the effects of using ozone in buildings for these purposes and warns consumers about misapplication of and health risks from ozone in buildings. Because at least some of these claims are based on marketing desire, not good science, and because ozone exposure can be both dangerous and ineffective indoors, We have collected some information and references on this topic.
• Ozone generators: The Hazards of Ozone & Ozone Gas Generators. This article gives an overview of the hazards associated with use of ozone indoors as a "mold remedy" or as an "air purifier". Ozone is widely promoted by ozone generating equipment companies and cleaning services for use in indoor building environments to deodorize, disinfect, "kill" mold, and for "general health".
• Ozone Toxicity & Ozone Gas Exposure Hazards This article discusses Ozone Toxicity in Buildings - A Summary of Hazards of Indoor Ozone, Ozone Generators, and Use of Ozone for Mold Remediation. While there are some important uses of ozone (such as for medical disinfection under controlled conditions), in general this is an idea which ranges from bad to dangerous in the home. This article explains the effects of using ozone in buildings for these purposes and warns consumers about misapplication of and health risks from ozone in buildings. Because at least some of these claims are based on marketing desire, not good science, and because ozone exposure can be both dangerous and ineffective indoors, We have collected some information and references on this topic.
• Paint Failures & Odors: How to Diagnose, Correct, & Prevent Paint Failure on Buildings. Paint odors: solvents and other chemicals in building paints or coatings are often a source of odor or paint smell complaints, even where low-VOC paints are in use.
• Pesticide Odors U.S. EPA advice on pesticides and possible pesticide contamination
• Pet odors: from dogs, cats, or other pets, source identification, testing, removal, are discussed beginning at our article "Cat Dander: how to inspect and test a building for past or current presence of cats, cat hair, cat dander, and cat allergens" This article discusses methods to check a building for animal allergens (cat, dog, etc) using as an example, Cat Dander: how to inspect and test a building for past or current presence of cats, cat hair, cat dander, and cat allergens. This website provides information and procedures for finding, testing, cleaning and preventing indoor mold, toxic black mold, green mold, testing building indoor air quality, and other sick house / sick building investigations. Here are research articles, inspection and testing procedures, and contact information for expert services. We give in-depth information about indoor air quality problems: causes of respiratory illness, asthma, or other symptoms such as neurological or psychological problems, air quality investigation methods, and remediation procedures such as mold cleanup, handling toxic mold contamination, and building or mechanical system repairs.
• Plastic odors: see Siding Odors below. This discussion also pertains to other vinyl or plastic materials used in buildings such as diagnosing odors from plastic trim, plastic or vinyl windows, window screens, doors, or similar materials.
• Septic or Sewer Odors: Diagnosing and Curing Sewer Gas Smells and Septic Tank Odors. This page describes how to diagnose, find, and cure odors in buildings including septic or sewage or sewer gas smells or "gas odors" in buildings with a focus on homes with a private onsite septic tank but including tips for owners whose home is connected to a sewer system as well. Sewer gases are more than an obnoxious odor. Because sewer gas contains methane there is a risk of an explosion hazard. In addition some writers opine that there are possible health hazards from sewer gas exposure, such as a bacterial infection of the sinuses (which can occur due to any sinus irritation). Depending on the sewer gas source and other factors such as humidity and building and weather conditions, mold spores may also be present in sewer gases.
• Septic or Sewer Odors: Wet Weather or Cold Weather Sewage or Septic Odors: Diagnosis and Repair Guide. This article discusses the diagnosis and correction of sewer gas or septic odors with focus on diagnosing odor sources and causes in cold weather. Some of the diagnostic steps pertain to all seasons.
• Sewer Gas Odors from drains: Diagnosing Clogged Drains & Septic System Backups: Is it a blocked drain or the septic system? - A First Step for Homeowners. This website explains how to investigate slow or blocked drains and septic system backups to distinguish between a probable septic system failure versus a probable blocked building drain. When a building drain is clogged or slow, or when there is a septic system backup, it's important to determine where the problem lies, since the repair steps can be quite different and costs can vary widely.
• Siding Odors: Vinyl Siding Failures, Diagnosis, Repair, Proper Installation: Siding, window, screen, & other "plastic" odors: We've investigated a number of reports of strange odors in residential buildings that were ultimately traced to vinyl or plastic which was outgassing. We've observed this phenomenon with vinyl siding, plastic or vinyl window or door screens, and plastic or vinyl windows. A key diagnostic step was the observation that the odors were strongest when the material under investigation was exposed to sunlight or other sources of heat.
