2. Water in the
Middle East
is a scarce commodity
Demand and the actual consumption of water is far beyond
the annual rate of replenishment, exceeding the safe yield.
Annual renewable amount to about 1,400 m3
per person per year - less than 20% of the global average.
Closing the Gap between Water Availability (Supply) and Demand .
3. All major water resources
in the region are
transboundary –

Resources
4. The Goal: Bridging Over Water Shortage
Securing Sufficient & Adequate Water Supply by
implementing novel
water innovations and technologies
1. Improving Water utilization efficiency:
irrigation & water application; water reuse;
water management: supply and quality
2. New Water: Reclaimed treated sewage

38. The Main Challenge:
Safe Discharge of Surplus Flow back/Produced Water Generated During
Production
Large volumes
Improper configuration
of sewage treatment
plants (STP’s)
Only a small fraction of
the flow back can be cut
into a new frac without
significant treatment to
remove TDS
On-site capacity
limitations frequently
require producers to
truck excess water to
alternative commercial
disposal facilities which
can be a major expense
and risk (Hazmat spills)
39. Water Reuse Practices and Brine Management Alternatives
Why Reuse?
• Potential to reduce discharges
• Minimize underground injection
of wastewater
• Conserve water resources
Byproduct Brine
• For now, evaporation or
discharge into drainage systems
are still the most common
methods in North America
(reuse of treated water is
growing in Australia). Hence,
brine minimization solution is of
critical need!

41. Real time monitoring of the heap hydraulic and chemical properties
Colombia 2013
42. The tailing dumps, the piles of waste material, and the superficial channels of effluents
increase the rate of contamination of the aquifers, affecting all the downstream rivers
and groundwater reservoirs with negative impact on agricultural activities that take
place downstream.
Objectives
Increasing water use efficiency for saving on water application by the mining industry.
Eliminating deep percolation of polluted water to protect local aquifers and eliminating further
contamination of downstream groundwater reservoirs.
The goals are:
Introducing an efficient water application method that decreases losses by evaporation and
eliminates un-necessary deep percolation;
Improving leaching efficiency in the heap-leaching production processes;
Containing the already polluted groundwater to avoid further contamination of the
downstream aquifers;
Assessing the hydro-chemical evolution of the percolating water along the vadose zone;
Assessing the hydro-chemical evolution within the sub-aquifer unites along the groundwater
flow trajectories.
Colombia 2013
43. Methodology
In order to face the aforementioned objectives one has to determine the following
parameters:
• Developing of combined under-cover high-low pressure sprinkling-dripping water
application system;
• Identifying the precise subsurface flow paths within the unsaturated (vadose) zone
from the on-surface treatment heap leaching piles and floatation and tailing lagoons
down to the local aquifers;
• Identifying the groundwater flow trajectories within and in-between sub-aquifer units;
• Identifying the hydraulic connectivity among the water bearing formations and the
neighboring aquifers;
• Quantify the water fluxes across the vadose (unsaturated) zone;
• Quantify the groundwater fluxes within and in-between sub-aquifer units.

72. The groundwater flow pattern and connectivity among sub-
aquifer units in the Mulde groundwater basin
Colombia 2013
73. Basic Assumptions for the Transient Mixing Cell Model (MCMtr)
The spatial structure, geometry, size and volume of the cells remain constant along the
entire duration of the model;
The isotopes and the dissolved minerals are inert and do not compose any chemical
reactions within the aquifer;
The dissolved ions are in pseudo-equilibrium with the rocks and soil minerals;
All potential unknown fluxes (groundwater fluxes between compartments of the system
and discharge of external contributors to the compartments) have been identified in terms
of its hydrochemical and isotopic composition.
Spatial and temporal variations in chemical and isotopic composition within the aquifer is
exclusively due to 1) variable mixing ratios among the recharge components, and 2)
dilution and mixing along the groundwater flow-paths.
Complete mixing of all dissolved constituents within the designated cells;
No gradients of hydraulic heads, isotopic and chemical compositions are allowed within
the cells, only across the cell's boundaries.
74. Groundwater and surface water resources combined with the
anthropogenic impact (industry and agriculture), create a complex
hydrological and hydro-chemical flow system.
The spatial distribution of various sources of pollutants along rivers
and within lakes is closely related to the relative contribution of each of
the active sources.
complex hydrological and hydrochemical flow system
Diffused sources.
Colombia 2013
75. Objectives
Identifying active sources of recharge: fresh water &
pollutants;
Quantifying the amount of deep percolation into each sub-
aquifer unit along every segment of the aquifer;
Quantifying the groundwater fluxes within and along
every water bearing sub-aquifer unit;

79. Sources of Groundwater Recharge and Possible Pollutants

80. Surface reclamation does not eliminate subsurface
downstream leachate and leakage!
Colombia 2013
81. Summary
The MCM is aimed for complex hydro-geological basins with lack of hydrological
information that eliminate the possibility to solve hydrological model based on the
continuity equation.
The MCM model identifies and provides a quantitative assessment of deep
percolation into groundwater from different sources such as mining and agriculture.
