When moisture problems occur and mold growth results, building occupants may start to develop mold exposure symptoms. They may report odors, allergies or a variety of other health problems indoors. Mold exposure symptoms can include breathing difficulties, headaches, allergic reactions, skin rashes, and aggravated asthma symptoms, among many others. The safety of building occupants and also of workers performing the mold repairs (remediation) must always be taken into consideration. Read more

Concern about mold exposure in buildings continues to be a significant issue. The bottom line is that mold has been around for eons and is not going away. It will grow whenever and wherever buildings get wet and materials suitable for microbial growth are present. So what is mold exactly and its effect on buildings? This article provides a general overview on this topic.
When visible mold is discovered in a property on materials or surfaces, a common question is, ‘can mold be cleaned?’ They may also wonder if they should clean the mold themselves.
Mold remediation contractors in Florida are generally conscientious, trying hard to bring each project to a condition where it will pass “clearance testing” (the Post-Remediation Verification inspection) on the first try. Some mold remediation guidance can be useful so that cleaning attempts are successful. If unsuccessful, this will certainly cost the mold remediation contractor additional cleaning time and therefore money, and it may damage their reputation with their client and/or insurance personnel. Depending on their contract, the contractor may be responsible for some or all of the cost of follow-up testing.
The devastating major flood damage seen in Houston and other areas of Texas is appalling. Many people are no doubt anxious to return to their homes and begin cleanup. However, homeowners must be aware that the hazards from this event do not go away when the water drains out of their home. There are significant health and safety risks, both immediate and long-term, associated with river or ocean flooding.
Recently, IET worked on several projects where sewage remediation contractors had difficulty achieving a sufficient level of cleanliness or sanitation to pass a “clearance” test. This would apply to contamination associated with a sewage backflow or other IICRC Category 3 “black water” event. These projects are, by their very nature, challenging. This article attempts to provide some sewage remediation suggestions for more effective and efficient project completion, addressing the areas where IET has often observed remediators having difficulty accomplishing.

Sewage Testing of Presence/Absence (P/A) for Indicator Organisms vs. ATP Measurement
Indoor Environmental Technologies (IET) uses two sewage testing methods for contamination in Post-Remediation Verification inspections. The goal is to determine whether remediation has been successful and the areas tested have been returned to a sanitary condition:
A sewage backflow into a home is a serious problem. Depending on volume and other factors, it may create severe sewage contamination in the indoor environment with potentially extreme health risks. Sewage contamination has the potential to be much more unsafe than even the most severely mold contaminated environment. Yet many homeowners and property managers are not aware of these facts and often underestimate the potential health and safety risks. This brief article on sewage contamination is intended to help address this disparity between perception and reality.
As part of determining whether an indoor environment is contaminated with excessive amounts of mold and requires remediation, Indoor Environmental Technologies (IET) routinely performs air and surface mold sampling or testing. While there are many types of mold sampling, IET uses two of them the most:
When weather is cool but humid for extended periods, the AC does not run for long (if at all), and there is no way to remove internally-generated humidity. Humidity can build up to the point where it begins to cause not only condensation, but extensive mold growth on window surfaces and elsewhere.
