level at this well was erroneously recorded by the probe since the November 2017
visit.

✓ 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, has been recorded at Banning M-8. Levels at Banning
M-9 have fluctuated within a 10-15 feet range during the same period.

✓ 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 2,218 ft.
The level at this well declined by ten feet before recovering again over the last six
months. Water level at BCVWD No. 25 seems to be in sync with BCVWD No. 2
based on the short recording period of only two months.

Troubleshooting Issues

The following malfunctioning issues were encountered during our July 25, 2016 field visit:

✓ YVWD Well No. 34 – Both communication cable and probe were not working at
this well prior to the November visit. At that time a new probe was installed;
however, it did not record the water level information properly. This probe was
removed at the January field visit and another new probe was installed. It was
also observed that the reason there is no communication with the probe inside the
well is that the existing communications cable has been cut at several locations. A
new cable needs to be ordered for this well.

✓ The probe was replaced, but the 400 ft communication cable was not replaced at
this time; a new 400 ft cable needs to be ordered for this site.

✓ Sun Lakes Well – A new 200 ft communication cable was installed during the
November visit and it is working fine as we were able to communicate with the
probe; however, the information collected by the probe did not make any sense.

✓ Banning M-8 – The communication and probe equipment at this well have been
very reliable until now. During our January visit, we were in the process of
sounding the well when a somewhat violent force took the communications cable
away from Mr. Jason Vasquez, a City of Banning Water Department staff member.
It seems like a portion of the casing collapse while we were sounding the well.
This action resulted in the sounding cable being stuck along with the
communications cable. We were able to retrieve the communications cable and
water level probe. However, after close to 45 minutes of trying to dislodge the
sounding probe we gave up as it was impossible to remove. The sounding probe
was stuck at 330 feet below surface and could not be dislodge. As a result, the
sounding cable was cut and let go. Thereafter, we made several attempts to
reinstall the water level probe, but were not successful as the cable kept on
