SQIDEP Myth: Test Sites Can be Selected to Favour Device Performance
Myth Claim: You can skew the SQIDEP results by putting the test site in an area that heavily favours the performance of the device.
Following SQIDEP’s 5.2 Framework for Reporting, you must submit catchment characteristics including grade & land use type, including photos. Also, PSD’s (particle size distribution) for influent and effluent must be submitted as per 5.2.h.
For example, Page 4 of the SPELFilter SQIDEP Evaluation Report shows that the land use is light industrial and considered to be representative of generating typical pollutant.
These clauses are designed to exclude a claimaint from picking a site such as a rainforest or beach front with lots of organic matter, or coarse sand/sediment, or a heavy vehicle yard with abnormally high loadings. These are not typical sites and will result in artificially high device performance.
