“HLR is directly associated with the wastewater applied to the “soil," but it is also an indicator of contaminant mass flux. The high flux of contaminants in the soil reduces the efficiency of contaminant removal and increases the chance of the pollutants reaching groundwater.
According to a recent scientific review, the typical person produces 3.4 lbs of wet wastes or .2 lbs of dry matter waste per day (10). To manage that waste we use 18.5 gallons (154 lbs) of potable water each day. As we move into drought and greater climate uncertainty and become critically aware how our reefs are impacted by human wastewaters, we need to ask, is the smart?
