Recharge rates have been estimated at monitoring bore locations in the basaltic aquifers of the Nulla and McBride basalt provinces. Recharge estimates have been calculated using the \u201cchloride mass balance\u201d method. The chloride mass balance process assumes that the chloride ion is a conservative tracer in precipitation, evapotranspiration, recharge and runoff; and that all the chloride is from rainfall, instead of for example halite saturation or dissolution processes. So the volumetric water balance and the flux of chloride balance must both be true. Assuming that runoff and evapotranspiration are negligible (so approximated by zero), the equation is simplified:\nWater balance P=ET+R+Q\nWater balance multiplied by chloride concentrations (chloridefluxbalance) \nP\u2219Cl_ppt=ET\u2219Cl_ET+R\u2219Cl_gw+Q\u2219Cl_riv | \u0394Cl_reac\u22480\nAssumptions to simplify equation P\u2219Cl_ppt=R\u2219Cl_gw | Q\u22480 & ET\u22480\nRearranging
