EPA bans use of water tested at 500 and above. Qualcomm tap water tests out at 484. The new "Culligan" faucets test at 484. Filtered water is usually 25 (between 0 and 50). Qualcomm water using the new Culligan is likely at times over the EPA limit. Don't drink the water. You've been warned.
You can buy a water tester on Amazon if you care about yourself. No point in worrying about your job if you aren't healthy.
You're welcome.
