a

As water managers, it is our
responsibility to project both water
availability and use-and our customers
expect that we will ensure that the
availability will always exceed their use.
We have become quite good at predicting
usage with reasonable certainty given a
specific mix of residential, commercial,
industrial and agricultural uses. Our
estimates of availability, on the other
hand, are at best shrouded in the mists of
prognostication or worse, simply a mirage
of ignorance.

The certainty of
uncertainty
While we are continually developing
our ability to predict the impacts of climate
change on surface water and groundwater
availability, it's not as accurate as it needs
to be-particularly with groundwater.
With surface water, we have a visual
reinforcement of availability. However, with
groundwater there are few data points
from which to assess the availability of
water-and that has led to us historically

Water

FATHOM, AND GRAHAM SYMMONDS, SENIOR VICE PRESIDENT
& CHIEF KNOWLEDGE OFFICER, FATHOM

overestimate the storage of water in
aquifers. This is a fundamental issue,
as groundwater is currently the primary
source of freshwater for approximately two
billion people1 on earth. If the expectation

could be depleted to 90% of its total
storage in as few as 50 years. 2

is to rely on groundwater during drought
conditions, we need to understand where
it is, how much there is and how quickly
we are using it.
In an attempt to do just this, satellites
have recently been used to estimate the
volume of water stored in aquifers through
remote sensing. The results are alarming-
the water stored within 37 of the earth's
largest aquifers may be overstated by
several orders of magnitude. 2 Further, 16
of these 37 aquifers are characterized as
being in an Overstress, Human-dominated
Stress or Variable Stress condition.1 This
has significant impacts on understanding
how we are to survive in an increasingly
water-scarce world, and this uncertainty
in availability combined with the stress on
groundwater results in some disturbing
possibilities. In fact, recent studies indicate
that the Northwest Sahara Aquifer System

With the continuing uncertainty in
availability of groundwater and the impacts
that climate change is having on the
volatility of surface water and our natural
water delivery mechanisms, we are left
with the ponderous question: What
can we do?
Clearly, we need to be better at
managing our water supplies and better
at adapting to volatility. Our models need
better data, and our utilities and their
constituents need a better understanding
of how, when and where water is being
used. One of the primary means of
affecting that understanding is by providing
consumption information to customers. It
is critical, however, that this information be
both timely and relevant.
Informing customers of usage 30 to
60 days in arrears does little to achieve
timeliness. To encourage changes in
