Additional Information:
The well at this facility was the first Miocene well used for drinking water in Glynn County
Recently added 20 additional feet of drop pipe to the well (extra column in shaft)
and flow went to 1050 gpm
At time of visit there were 13 ft of water in gground storagge tank
One of HSPs operating during visit - gauge reads approximately 30 psi
There were daily chlorine readings listed in operator's log
Milltronics Hydroranger level monitoring
Block buildng for high service pumps and controls
