Survey Reports

Professionals can expect the test report by within 7-10 business days after Waverton Analytics have received their sample – the reports are e-mailed directly from the laboratory, immediately upon completion of the analysis.

The reports are easy to interpret and include the results of the analysis along with an indication of the likely sources of the chemicals found. Information from the report can then be used to assess the indoor air quality and if necessary, steps can be taken to reduce or eliminate offending sources of chemicals from the property.

VOC (VOCs & hidden mould) report

The VOC report is divided into five sections;

(i) Total VOC level reading (TVOCs), which provides a general measure of indoor air quality in the house or building, along with an indication of whether this is “Normal”, “Moderate”, “Elevated” or “Severe”.

The blue line on the chart illustrates how the TVOC level compares against levels from all houses tested by Prism over several years.

(ii) Total mould-specific VOC level reading (TMVOCs), which provides a measure of total VOCs emitted by actively growing mould, along with an indication of whether this is “Minimal”, “Low”, “Elevated” or “Severe”.

 

Again, the blue line on the chart illustrates how the TMVOC level compares against levels from all houses tested by Prism over several years.

(iii) The Contamination Index™ (CI), which provides a breakdown of the total VOCs into the products and materials that are likely to be the source of the chemicals that are present.

There are three main categories of VOC sources including “Building related sources”, “Lifestyle related sources” and “Mixed building and lifestyle sources”.

Information relating to these categories is presented in the report using two different formats:

A “pie-chart” is used to illustrate the breakdown of the VOCs found in the air sample into the three CI Source Groups:

Each CI Source Group category is then listed along with a range of products that could be responsible for emitting the chemical vapours detected, including their individual contribution to the total VOC (TVOC) level.

(iv) The top 10 most significant VOCs present– listed in descending order as individual chemical compounds.

This tabular display includes a value for the level of each compound along with a description of the likely sources of such chemicals in terms of commonly used products:

(v) Hazardous Air Pollutants (HAPs) – this is a listing of 18 toxic air pollutants that are known or suspected to cause cancer or other serious health effects.

In each case the estimated level detected is displayed along with the NIOSH exposure limit:

The information provided in these reports can be used to improve indoor air quality by locating and removing the source of the chemicals identified. In circumstances where this is not possible then the issue may be addressed by improving chemical storage methods or employing ventilation or air-purification systems to reduce VOC levels.
