QUALITY CONTROL AND QUALITY ASSURANCE PROCEDURES USED DURING THE INDOOR AIR QUALITY MONITORING PROGRAMME IN WESTON VILLAGE, RUNCORN

摘要

As part of an assessment of the legacy of more than 160 years of industrial activity around the former ICI Runcorn site, an indoor air quality survey of 145 properties in Weston village, Runcorn in Northwest England was performed. Two redundant quarries near the village had been used for the historical disposal of chemical waste from about 1930 until the 1970's. A borehole investigation showed concentrations of hexachlorobutadiene (HCBD) in the subsurface that had the potential to impact air quality in neighbouring properties. The Building Research Establishment (BRE) and QinetiQ developed an analytical method (Crump et. al., 2002), with a linear working range of 0.003 parts-per-billion by volume (ppbv) to 10 ppbv, and the development work has been peer reviewed. This paper describes the importance of detailed quality control (QC), quality assurance (QA) and peer review procedures to ensure that air quality monitoring data meets data quality objectives and the expectations of all stake holders.
