ATI quality scores: Major elements 93/100, Pollutants 100/100, Base elements 100/100.
Heavy metals: none detected — aluminium, antimony, bismuth, lead, cadmium, lanthanum, thallium, titanium, tungsten and mercury all below detection.
RO water check: the reverse-osmosis water tested alongside the salt came back clean — every element below detection. The RODI filter is doing its job.
