1 Answer Sorted by: 1 If you want 10 ppm copper in 2 liters of water, the best way to make it would be to start with some soluble copper salt, like CuSOX4⋅5HX2O C u S O X 4 ⋅ 5 H X 2 O, make up a convenient concentration (like 1%), then dilute it to 10 ppm. As was mentioned in the comments, copper metal is not noticeably soluble in water.

Geochemical processes and the effects of natural organic solutes on the solubility of selenium in coalmine backfill aquifers were investigated. Backfill and groundwater samples were collected at coal mines in the Powder River Basin, Wyoming. Backfill was generally dominated by aluminum (14,400 to 49,000 mg/kg (milligrams per kilogram)), iron (3,330 to 23,200 mg/kg), and potassium (7,950 to 18,00
