Abstract The sources, fluxes and sinks of dissolved organic carbon (DOC) in a groundwater recharge environment and along a well defined flowpath were investigated in a shallow unconfined aquifer system in Central Ontario, Canada. The initial recharge flux of DOC in the upper vadose zone is estimated to be 49 kg ha −1 yr −1 , however, biochemical recycling and retention processes deeper in the vadose zone result in a net DOC flux of about 9.8 kg ha −1 yr −1 to the groundwater. Within the aquifer… CONTINUE READING
