Are there harmful effects of water softener discharges on household septic tanks?

According to the Canadian Water Quality Association, water softener regeneration discharges do not pose a problem to septic systems or to the leach field. Studies have shown that water softener regeneration waste does not interfere with the septic tank system drain field soil percolation and can actually improve soil percolation, particularly in fine-textured soils.
