✓ Figure No. 5 - This figure illustrates levels at three wells owned by the City of
Banning in the Southeast portion of the basin. While water level at the Old Well
No. 15 (Chevron Well) has been fairly flat over the last two years, a somewhat
significant and steady decline, close to 23 feet, has been recorded at Banning M-
8. The probe at Banning M-8 was removed during our visit in late January 2018
as there seems to be an obstruction in the well at a depth of approximately 350 ft
below ground. City staff has indicated that the pump at this well will be pulled later
this year at which time we may have an opportunity to use this well again. Water
level at Banning M-9, recorded at an elevation of 2,127 ft, is at the lowest elevation
since the monitoring program began in 2015. The water level at this location has
declined by 17 ft over the last six months.

✓ Figure No. 6 - This figure illustrates recorded water level at BCVWD No. 2 and the
new monitoring well BCVWD No. 25. Over the last two years, the level at BCVWD
No. 2 has increased by over 20 feet topping in May 2017 at an elevation of 2,218
ft.; current water level is slightly lower. Water level at BCVWD No. 25 were in sync
with BCVWD No. 2 until production at this well (25) started in April 2018 when the
well pumped up to 18 hours per day during non-TOU hours. Daily values shown
in this graph after April 2018 indicate the average value during a 24-hour period
including pumping and non-pumping hours. Figure 6A provides a better indicator
of static water levels at BCVWD No. 25 since daily values recorded at 5:00 PM
were used to reflect a static condition.

New Equipment Installation

✓ Oak Valley No. 5 – A new monitoring probe will be installed at this location this
afternoon.

Troubleshooting Issues

The following malfunctioning issues were encountered during our September 25, 2018
field visit:

✓ BCVWD No. 2 – Communications cable did not work during the September visit.
Communications cable may need to be replaced.

✓ Oak Valley No. 5 – Communications cable and probe are not working. The probe
will be replaced this afternoon and potentially a new communications cable
installed.

✓ The new water level meter may need to be sent to Solinst for repairs as the cable
was peeled when BCVWD No. 2 was being measured. This cut is making the
water level alarm to sound inconsistently as it beeps even when the water level
probe is out of the ground.
