You can see one well being drilled at 33.812000000 -118.185600000 - and just north of that location, you can see one (probably) active pump.
Just immediately west of that location, you can see other pumps, likely active, (white pickup truck with open door beside one) - and a block further west are two more active pumps, with associated storage tanks.
Half a block to the east and south of the one being drilled is another probably active pump.
The question regarding why old capped wells in Long Beach, known to be full again, could not be opened and pumped again by the owner of the well, still remains an unanswered question - the likely impediment being federal and state government standing in the way.
