Boron in water after the watermaker an issue?

U of M has come up a method to remove “harmful” boron in.drinking water coming from desalination.

I never heard of boron as being an issue.

Am I missing something?

I looked up a couple old water tests. No Boron. In the Pacific NW & Alaska.

I make water year round, in salt and fresh. I prefilter.

Here's a discussion of the problem or potential problem:

Apparently boric acid can pass through the membranes of a watermaker, and is present in very salty seawater in some tropical seas.

Re: Boron in water after the watermaker an issue?

Boron is ubiquitous in seawater, at a concentration range of 4–6 mg/litre.
The World Health Organization, the European Union, and Health Canada have established health-based limits for boron in drinking water, ranging from 1 to 2.4 mg/l.
According to the WHO regulations, the boron concentration should be reduced to less than 0.5 mg/L for drinking water.
It is also reported that, this limit is rarely reached for conventional reverse osmosis desalination plants, equipped with commercially available membranes.
