Remember, there is always a likely exception to every rule or generalization, and because there is no direct relationship between the collected indoor and outdoor samples, performing a direct comparison with limited sampling can be and often is misleading.

The range of expected variability when comparing limited data sets must also be considered. We have sampled multiple sites on the same day with wildly different outdoor sample results. If you compare inside to outside, you must take into account other sites sampled to understand and interpret variability.

We have completed thousands of samples over the past plus years, so we have a leg up on data interpretation. We also remediate mold, what you learn from opening up walls and climbing in tight spaces teaches you a lot about how mold grows and where. Couple spores to note:. The majority of the hundreds of sub-species are allergenic; only a few are toxic.

This group of species typically grows with the humidity in the air as its water source. Cladosporium — the most common mold species and is considered to be an allergenic. Certain housekeeping issues can be a contributing factor when elevated levels are noted, so room and building condition are very important to note to understand the results.

Curvularia — another common allergenic mold. Stachybotrys — the most common toxic mold species, but not all sub-species are toxic. These species need a direct water source to grow. Memnoniella — a sister mold to Stachybotrys. The two species will grow together; also considered a toxic mold due to production of mycotoxins.

Mold spore species and levels differ within each state if there are regulations determined at all agreements are hard to come by with analysts and scientists.

A comparison to an outdoor air sample is usually used as the rule of thumb. Understanding how these grow and where in the room samples were acquired are key to being able to understand the results. If water intrusion or mold was not found during the, these levels can be caused by normal life in an enclosed environment.

Again, room and building condition. Room environment including dusty home or type of HVAC system can have an amplification effect. Further inspection is warranted. Mold should be able to be visually assessed unless renovations covered over the mold i.

A perimeter clean-up is needed if a mold spore source has been identified. If no water intrusion or mold issue was found including behind walls , the duct system may need to be cleaned and a general cleaning of the residence could be a contributing factor. Clean up will be required and should be performed by a Professional Mold Remediator, remember approximately 11 states have mold regulations so hiring a state-licensed mold company may be impossible.

This is because flipped homes represent properties that have had deferred maintenance and were priced to sell below market rates.

Meaning the property was sold cheaply allowing the flipper to rehab the home and sell for a profit. Guaranteed the flipper did not account for mold remediation in the rehab budget. Meaning post rehab when the buyer hires Curren to perform a mold inspection we find mold.

It is a high percentage and speaks volumes regarding why mold due diligence is so important. That said you can also have testing performed that contradicts the visual assessment of the room. For example, you can sample a room that has gross visible mold growth but you get results that are not what would be expected based on room conditions.

This is usually attributable to the sample collection process, including a sampler, height of sample, air flow, pump calibration, damage sampling cassette, room temperature as well as a variety of factors. Conditions under which indoor mold growth can occur include:.

What is capillary action? Adhesion of water to the walls of a vessel will cause an upward force on the liquid at the edges and result in a meniscus which turns upward. The surface tension acts to hold the surface intact.

Capillary action occurs when the adhesion to the walls is stronger than the cohesive forces between the liquid molecules. Mold and fungi require three basic criteria to colonize the inside of a building including. Moisture sources in buildings occur most commonly through moisture intrusion in walls and foundations, or as condensation around windows or in HVAC systems.

In some parts of country such as the Southeast U. for example, the relative humidity during certain times of the year is high enough to act as a significant moisture source alone. Skin cell fragments are a significant food and colonizing source where a high occupancy exists, or adequate housekeeping is not performed.

Molds colonize most readily where air disturbance is minimal. For this reason, mold colonization occurs most frequently in closed or concealed spaces such as closets, storerooms, basements, refrigeration units; or on the back or underside surface of furniture.

The Best Soil Test Kits Tested in 2023

InterNACHI inspectors who perform mold inspections often utilize air sampling to collect data, which has become commonplace. There are several types of devices used to collect air samples that can be analyzed for mold. Some common examples include:. Samples are generally best taken if visual, non-invasive examination reveals apparent mold growth or conditions that could lead to growth, such as moisture intrusion or water damage.

Musty odors can also be a sign of mold growth. If no sign of mold or potential for mold is apparent, one or two indoor air samples can still be taken, at the discretion of the inspector and client, in the most lived-in room of the house and at the HVAC unit.

Outdoor air samples are also typically taken as a control for comparison to indoor samples. Two samples -- one from the windward side and one from the leeward side of the house -- will help provide a more complete picture of what is in the air that may be entering the house through windows and doors at times when they are open.

It is best to take the outdoor samples as close together in time as possible to the indoor samples that they will be compared with. Residential home inspectors also should not take samples in a commercial or public building.

In any areas of a house suspected or confirmed to have mold growth, air samples can be taken to help verify and gather more information. Moisture intrusion, water damage, musty odors, apparent mold growth, or conditions conducive to mold growth are all common reasons to gather an air sample.

Samples should be taken near the center of the room, with the collection device positioned 3 to 6 feet off the ground.

Ten minutes is an adequate amount of time for the air pump to run while taking samples, but this can be reduced to around five minutes if there is a concern that air movement from a lot of indoor activity could alter the results. The sampling time can be reduced further if there is an active source of dust, such as from ongoing construction.

Sampling should take place in livable spaces within the house under closed conditions in order to help stabilize the air and allow for reproducibility of the sampling and measurement. While the sample is being collected, windows and exterior doors should be kept shut other than for normal entry and exit from the home.

It is best to have air exchangers other than a furnace or fans that exchange indoor-outdoor air switched off during sampling.

Weather conditions can be an important factor in gathering accurate data. Severe thunderstorms or unusually high winds can affect the sampling and analysis results. High winds or rapid changes in barometric pressure increase the difference in air pressure between the interior and exterior, which can increase the variability of airborne mold-spore concentration.

Large differences in air pressure between the interior and exterior can cause more airborne spores to be sucked inside, skewing the results of the sample. It is helpful to think of air sampling as just one tool in the tool belt when inspecting a house for mold problems.

An air sample alone is not enough to confirm or refute the existence of a problem, and such testing needs to be accompanied by visual inspection and other methods of data collection, such as a surface sample.

Indoor airborne spore levels can vary according to several factors, and this can lead to skewed results if care is not taken to set up the sampling correctly.

Also, since only spores are collected with an air sample and may actually be damaged during collection, identification of the mold type can be more difficult than with a sample collected with tape or a cultured sample.

This is because they can detect long chains of spores that are still intact. These chains normally break apart quickly as they travel through the air, so a sample that reveals intact chains can indicate that there is mold nearby, possibly undiscovered during other tests and visual examination.

A greater conductivity value implies that the water contains more dissolved compounds. The quantity of corrosion rose as conductivity increased. As a result, the higher the conductivity of water, the more corrosive it is. To prevent corrosion, nitrite must be kept in the boiler water.

If your computer-generated test results tell you to add outdoor boiler water treatment, make SURE you add an additional one-half gallon of water treatment to what is recommended.

If you take care of your water, your water and your furnace will take care of you. If you need additional supplies, contact your dealer. You can also fill any ml pop bottle and download and print a mailing label.

After filling out the mailing label secure it to the bottle. Open your boiler furnace drain located at the bottom rear of your furnace for seconds or until the water runs clear. Be careful as the water can be extremely hot and come out with a lot of pressure.

Once the sample water is cool, fill one of the supplied test bottles. Next, complete the mailing label including your email address, model number, and the serial number of your furnace. You will also want to note on the label if your furnace water contains any antifreeze or additional chemicals.

Results can take up to four weeks, or eight weeks if no email address is included. The test will determine if your water is in the recommended operating levels.

You will receive a water test report outlining what you should do if your water needs adjusting. Treating the water allows us to control the levels of dissolved gases and solids that can cause corrosion, scaling, and damage to equipment.

And treatment helps protect everything the system water touches, not just the furnace. You can add water treatment through the fill pipe located at the top of the furnace when initially filling the furnace with water or after testing.

Water treatment may need to be added or your furnace may need to be drained and flushed and water treatment added. If any action is required, operate the furnace with the pumps circulating for at least 48 hours, then take another sample and mail it to the test lab.

We usually inform the caller that it is very difficult to draw any conclusions about their air quality test without having seen their property first hand. A report, no matter how detailed it may be is no substitute for an actual site visit or air quality test.

We also inform the caller in most cases that we usually do not like relying on information from a third party due to a variety of reasons. The report does not necessarily show me that the indoor air quality test was performed fully and properly. It does not show if the samples in the case of laboratory samples were somehow mishandled or cross contaminated and it does not necessarily provide calibration information, equipment set up, etc.

In short, we usually recommend that we perform our own independent indoor air quality test. Lately, we have seen more and more inspection reports without an ambient or outdoor sampling area.

In other words, the indoor air quality test was performed without outdoor sampling. An outdoor sample is extremely important! It serves as a comparison or baseline for all of the air quality parameters that are being analyzed. Aeroqual does not recommend a second factory calibration, but rather replacement after two years of operation.

See a range of frequently asked questions on calibration here.

The equipment described below is useful in measuring the optical properties of test samples—their ability to reflect or transmit light. We use the equipment described below to characterize the mechanical properties of test samples—strength, adhesion, and ability to keep out moisture and oxygen.

We use these temperature- and humidity-controlled chambers to test for weathering durability, corrosion on mirrors, delamination of polymers under controlled conditions, and other research.

The conditions listed along with the equipment represent current tests. We use these temperature- and humidity-controlled chambers to test samples under simulated and accelerated conditions.

Nearly 40 test beds surround the OTF building. These test beds allow researchers to characterize the electrical output performance of modules under outdoor conditions, test the long-term performance and stability of PV modules and systems under standard and accelerated outdoor conditions, and measure the performance of hybrid systems.

Systems used for PV measurement include Standard Outdoor Module Characterization, Long-Term Module Outdoor Performance and Stability, and Grid-Tied PV Systems Testing. Researchers use two I-V measurement systems to measure the electrical output performance of PV modules under outdoor conditions that are as close to possible to standard test conditions.

One system is the Standard Outdoor Measurement System, a fixed system on which modules are placed for testing and can track the sun. For each measurement, we use a pyranometer and a silicon reference cell in a module package to determine the total irradiance, and a spectroradiometer to determine spectral content of the sunlight between and 1, nm.
