Zinc calculations based on 1.2 ppm:
(1.2 ppm)*(0.99859 mg/L) = 1.19863 mg/L
(1.19863/14)*100% = 8.5714%
This means you will have to drink 1 liter of water to get 8.6 percent of your daily recommended intake of zinc.
Copper calculations based on 0.6 ppm:
(0.6 ppm)*(998.59 mcg/L) = 599.154 mcg/L
(599.154/900)*100% = 66.5727%
This means you will have to drink 1 liter of water to get 66.6 percent of your daily recommended intake of copper.

Micronutrient deficiencies rarely occur in New England soils; therefore, an Optimum Range has never been defined. Values provided represent the normal range found in soils and are for reference only.

This whole urban permaculture thing would be a heck of a lot easier if the house were just sort of not there...
