ABSTRACT
Points of concern: California water code requires recycled water use for landscape irrigation. Likely, a high amount of water softeners are used in the area.
1. Regular leaching of greens required. 2. Note increases of sodium and chlorides most significant between potable
and recycled samples. 3. Bicarbonates will be complexing a large part of the Ca concentration. 4. Sulfate levels >180 ppm are a concern and potential problem for black-layer. 5. Sodium levels are higher than Ca levels in all cases.
