This is a blended media, and it is built on the same materials as the single medias that carry a California restriction. We have taken it off direct sale while we confirm its status with Clack Corporation.
- The media is 40–60% crystalline quartz by weight. That is not a trace impurity, it is most of what is in the bag — taken from Clack Corporation's own safety data sheet.
- Quartz is on California's Proposition 65 list as a cancer-causing chemical. The safety data sheet says so itself, naming Quartz (SiO2) under its Proposition 65 section.
- No separate data sheet is published for this blend, so Clack Corporation has not stated a California position on it either way. That is exactly why we are asking rather than assuming.
- Other distributors refuse California orders for this media and say plainly that Proposition 65 is why. One states it as an agreement with their supplier.
The risk is breathing the dust while you load the tank, not the treated water — the media is certified to NSF/ANSI/CAN Standard 61 for drinking water contact, and once it is wetted and in the vessel there is no dust. That is our reading of the documents, not a legal opinion.
We have taken this off direct sale for now. Call 408-969-2688 or email sales@foreverpureplace.com — we will get a direct answer from the manufacturer, quote you if it turns out to be fine, or set you up with one of the alternatives below.
Quoted from the manufacturer's own published documents, checked against the current revisions on the manufacturer's website.
Both do the same job in the same backwashing vessel, and neither manufacturer places a California restriction on them. Call 408-969-2688 if you want us to match one to a water test.
The straight swap for iron and manganese, and the one with nothing to disclose — it is a clinoptilolite media with no crystalline silica at all, and its safety data sheet states plainly that no Proposition 65 chemicals are present. It also filters far finer than Birm, down to 3 micron. It costs more per cubic foot.
The long-established iron and manganese media, widely used in California including in municipal plants, and its manufacturer imposes no California restriction. Be aware it is built on a silica sand core — 90–94% crystalline quartz, more than Birm — so choose it for the absence of a restriction, not for the absence of silica. It also needs an oxidant.
