Heavy metal ICP results?

[GlassMunky]

i just got back the results from my first ICP tests on both of the home systems I run.
Both seem to be showing high levels of things like lead, arsenic and selenium among others. I'm not sure where these would be coming from, or what to do to get rid of them...

I run a dual membrane dual DI RO/DI system and all filters are changed regularly and water tests at 0TDS.

Anybody have any ideas on where it came from? Or more importantly, how to get rid of it and keep it from coming back?

First pic is the results for our 90G SPS tank tied to a 40B nem tank with a common shared 30G sump.

Second pic is the results for our living room mixed reef 70cube/30sump

IMO I don't think any of those are anything to worry about at those levels. I think the most common way elements get leached into a system is GFO/Phosban but neither of those will give you what you have there. And its seems so close to the measurable amount it could even be a mistake. Wouldn't worry about it unless your having issues, at which point I would still focus elsewhere. Is this Triton? I've never seen the results displayed this way.

I'm sorry, I cannot see the headings of the columns, but isn't the lead value ( and some others) negative?
