They don't have it posted online on their site, nor the EPA website, however you can call Cal Water Service at 310-257-1436 to request a report. They also have a 1-800 number on their website, but I figure that might go to Cal Water Corporate and not the substation which is the 310 number. They are the supply for Redondo and Hermosa, just FYI.
We'll have to trade homebrews when I'm back in the area. Cheers!
