Some inside information into how and why we select the right method of evaluation for your project.
The bacterium Clostridium difficile (yellow), which frequently causes diarrhoea in people who have been on antibiotics, produces a compound that smothers the growth of other gut microbes.
Pure Air Solutions Services offers testing services to homeowners whose homes have been affected by sewage back-ups. An often traumatic experience with a significant amount on contamination to textiles, Pure Air Solutions Services understands the meaning of being able to offer a confirmed ‘clean’ result.
Listed below is some of the industry discussions surrounding various methods of cost effect analysis to offer home owners however the downfalls are also accounted for. Typically sampling for sewage contamination is costly and there’s good reason why. In order to obtain a true indication of any parasites, viruses or bacteria lurking on your contents, at Pure Air Solutions Servives we incubate the samples and culture them to find if they are truly clean.
A cost effect method known as Luminescence tests for ATP is one choice, as there many bacteria/mould luminesence testing devices making this method of analysis not only cost efficient but offer immediate results.
The downfall to ATP testing is that it has confounders- If one wants a clean non-organic surface, ATP testing would be useful but not specific. You are checking to see if the surface was cleaned for ATP containing material - hence why it works for food industry and health care, but I would not expect a virus to have or make ATP, thus, you are missing the testing of viruses and are presuming that the general cleanliness of ATP sources is a sufficient surrogate. In addition to this, luminescence type testing devices do not differentiate pathogen bacteria from non pathogens often skewing the results.
Regardless of the sampling method performed, for the most accurate representation of results one would need to compare pre and post remediation results. If for whatever reason pre-remediation samples are unavailable, since sewage must be cleaned up immediately, one must take extra care into ensuring a control area sample is then collected to compare to the area that was cleaned up.
