If laboratory testing indicates any media texture-related parameter is not within the design or product specification ranges, notify the media or topsoil supplier, issue a “do not install” order to the construction site supervisor and contact the design professionals and property owner or project manager to determine corrective actions.

If laboratory testing indicates any media texture-related parameter is not within the design or product specification ranges, or the acceptance criteria ranges, schedule investigative work to do further sampling and testing to determine the affected area and depth and decide on corrective actions. Corrective actions for [[bioretention]] and [[bioswale]] filter media where the proportion of silt- and clay-sized particles is too high may involve removal of [[mulch]], stone cover and plantings and tilling the top 20 - 30 cm, or removal and replacement of part or all of the filter media with material that is within acceptable tolerance ranges of design specifications.
