Since water is a key ingredient in beer, it being mostly water, polluted water threatens beer quality.
Thursday a group of 59 craft breweries sent a letter to the U.S. Environmental Protection Agency and U.S. Army Corps of Engineers opposing the agencies' "Dirty Water Rule" proposal to slash clean water protections for waterways around the country.
These brewers, who are partners in NRDC's Brewers for Clean Water campaign, are standing up for safeguards that protect the sources of clean water on which their businesses depend.

If it is enough for these fish it is enough for humans. Aquarium grade is higher quality than human/edible grade.
From your third link:
I have no idea what "molecularly smaller" means, but this is the most widely used pesticide:

So they are saying that somehow the much larger pesticide molecules can fit through smaller pores?

Methane (CH4) has molecular weight of 16.043 (slightly less than water). Assumign they are all "organic" molecules, I don't think any pesticide could have MW less than that.
