Hey guys, it is yet another thread asking for some assistance with my water report. I recently got my town's water department to conduct a new "secondary contaminant" report and give me the results. I have done my best to summarize them below and have also attached the full report.
From this I calculated the following values:
I run this water through a 10" carbon block filter, but it is my understanding that should not affect the above concentrations. To my inexperienced eye these results don't look great (High chloride, high sodium). I mainly brew NE-styled hoppy beers and am looking to have fairly high chloride/sulfate in a 1:1 ratio at around 150-250ppm (going to experiment with this). I am not sure if I should care about hitting other target ion concentrations (Mg, Ca, etc) or just focus on the chloride and sulfate.
I was hoping that you guys could check this report and my calculated values to make sure that I am in the right neighborhood and provide any advice about if I should try to work with this profile or focus on diluting or building off RO or DI. I have access to deionized water from my work, however I have to haul whatever I want a fair distance so I would like to minimize any need for DI water.
At least initially it looks to me like I should dilute with ~3-5 gallons of DI water (going to use an empty 1/6bbl keg for transport) and then use CaCl2 and CaSO4 with minimal MgSO4 to hit my target concentrations.
As always, any advice is greatly appreciated!
