cemetery grounds. The water level at this well continues to fluctuate over a 20-
foot band. Conversely, the water level at the Sun Lakes well has fluctuated
minimally over the same period as it decreased three feet over the last three years.

✓ Figure No. 5 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, was recorded at Banning M-8 between the summer of
2015 and the winter of 2017. The probe at Banning M-8 was removed 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 confirmed that the pump has
been pulled from this well and they are going to run a video log of the well before
authorizing the reuse of this well for monitoring purposes. Water level at Banning
M-9 has fluctuated in a 13-foot range, between 2,144 ft and 2,147 since monitoring
began in the summer of 2015. Currently, water elevation is at 2,138 ft.

✓ Figure No. 6 illustrate 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 2,220 ft.
Since, it declined about six feet, but it is back to the highest recorded elevation.
Water level at BCVWD No. 25 is in sync with BCVWD No. 2 despite of pumping
close to 18 hours a day. The hourly collection of water level data has allowed us
to identify static levels at this well during the non-pumping hours as the aquifer
recovers rather quickly in this portion of the basin.

New Equipment Installation

✓ Install new communications cable and probe at BCVWD Well No. 29 – 500 ft

✓ Replace communications cable at BCVWD Well No. 2 – 500 ft

✓ Replace communications cable at Oak Valley No. 5 – 200 ft

Troubleshooting Issues

The following malfunctioning issues were encountered during our January 22, 2019 field
visit:

✓ BCVWD No. 2 – Communications cable at this well has not worked for over six
months and needs to be replaced. A new 500-ft cable has been ordered to replace
the existing 550-ft cable.

✓ Oak Valley No. 5 – Communications cable is not working; however, probe
continues to record hourly water levels. Probe was pulled from the well to
download data and lowered again. A new 200-ft communication cable has been
ordered.

✓ The new water level meter is currently being repaired.
