[BC] the solder I'm using

[Mike McCarthy]

No...it is not.  Anything which references rosin core solder is not
suitable for ground system work.

Any welding supply or HVAC supply house should have 5% or 15%
Stay-Sil/Silvaloy (both trade names) in stock or closely available. Both
are standard products in the HVAC industry.

http://www.airgas.com---search for "Stay-Silv" or P/N HAR15320F1

Anything less will not provide long term or reliable performance.
