This is a device-release basis on the water leaving the device; the sovereign drinking-water parametric values are a WATER basis on the supply as delivered and are disclosed as companions, never republished as the device's release ceiling.. No government sets a numeric heavy-metal limit for this product form, so every panel analyte is held under mandatory analytical control or a substantiated not-material determination rather than an invented ceiling.
