We have 340 ppm Arsenic; How do I filter for garden water
We have high levels of natural arsenic; I have googled filters but most are undersink for house water. I want a filter I can put on outside hose bib. What is the best?

Thank you for your question. We are not able to recommend a specific product, but I did a web search for ‘filter for arsenic hose’ and found this (but I am certain there are others): http://www.ecoonespa.com/spa-products/hosefilter/ You might be interested in this Extension article that discusses the actual risk of arsenic even entering plants, let alone posing a hazard to humans: https://www.unce.unr.edu/publications/files/ho/2009/fs0909.pdf Good luck!
