 I've looked for the source of the problem but have not seen it. A hint as
to why the figures are not displayed when the multicol package is used will
be much appreciated.

  Brief example attached (with separate figure so you can include it more
easily).

\begin_layout Abstract
Natural resource companies do not object to environmental regulations that
 are consistent and support predictability.
 Consistency and predictability are critical for decision making under condition
s of uncertainty.
 Natural ecosystems are inherently variable across a broad range of temporal
 and spatial scales; climate change, drought, and societal desires for sustainab
ility make people more aware of this variability.
 The science used for development and enforcement of environmental regulations
 has not kept pace with developments in ecological theory and the analytical
 tools capable of describing, characterizing, classifying, and predicting
 natural ecosystems as well as distinguishing natural variability from anthropog
enic changes.

\begin_layout Abstract
Because natural resource industries (agriculture, energy, mining) provide
 the base for all economic and societal activities it is critical that environme
ntal statutes and regulations be regularly updated to use the most technically
 sound and legally defensible scientific knowledge and tools.
\end_layout

\begin_layout Abstract
Mathematical models were the tools of choice when environmental statutes
 and regulations were introduced, perhaps because they were successfully
 applied to static components of the built environment such as buildings
 and bridges.
 While their limitations for highly variable natural ecosystems were accepted
 then, there is now no benefit to not replacing them with statistical models.
\end_layout

\begin_layout Abstract
This paper describes limitations in policy and regulatory decision-making
 based on mathematical models and explains how the appropriate statistical
 models avoid the subjectivity and rigidity of the former.
 Changing the basis of determining and justifying policy and environmental
 regulations is consistent with the concepts of regulatory science applied
 to human health.

Pit Lake Hydrodynamic and Water Quality Model (PITLAKQ)
\end_layout

\begin_layout Standard
PITLAKQ couples the models CE-QUAL-W2 and PHREEQC and adds new functionality
 to account for the pit lake requirements.
 It includes the most important processes in pit lakes.
 For example, several sources of acidity such as erosion or release from
 submerged sediments and spatially distributed groundwater inflow help to
 better represent pit lake conditions.
 Furthermore, PITLAKQ can account for the effects of water treatment on
 water quality.
 The two-dimensional model setup with one vertical and one horizontal dimension
 allows having sinks and sources with defined spatial locations.

\begin_layout Standard
Policies and regulations can be supported by demonstrably best available
 science by taking advantage of current knowledge in environmental data
 analytical methods and our understanding of ecological theory applicable
 to all natural ecosystems.
