Whole Effluent Toxicity (WET) Laboratory Reporting

The Region 8 NPDES WET Laboratory Reporting tool is a Microsoft Excel based form for use by WET laboratories to report bench data. This tool contains multiple tabs, macros (must enable content when opening for full functionality), drop-downs, and fillable fields to enable laboratory personnel to more easily complete WET reporting needs for NPDES permittees. The tool is protected to enable the fields to properly function; however, there is no password set if laboratories would like to use it as a template and further customize it for their needs.
