Field testing also allows for a more accurate assessment of filter performance for stormwater pollutants other than suspended solids.  These pollutants are subject to complex physical, chemical, and biological interactions that are not easy to replicate in a laboratory.

In Canada, the [https://sustainabletechnologies.ca/app/uploads/2023/11/SETV-Filtration-MTDs-PAS-2023-11-07-English.pdf '''Canadian Procedure for Field Testing of Filtration Manufactured Treatment Devices'''], developed by TRCA and the [https://www.scc.ca/ Standards Council of Canada] stipulates field testing requirements for Filtration MTDs.  This document was developed based on the [https://apps.ecology.wa.gov/publications/SummaryPages/1810038.html Washington Technology Assessment Protocol – Ecology (TAPE)]. TAPE provides a robust and scientifically defensible field evaluation methodology for proprietary and non-proprietary stormwater treatment technologies that is well regarded by stormwater practitioners, having been developed and continuously updated over the past two decades through an extensive third-party expert peer review process.
