2. Introduction
 Pit lakes may be rarely (or never) sampled.
 Unmanned aerial vehicle (UAV).
 New approaches involving the use of
unmanned aerial vehicles (UAVs, or
drones) for pit-lake monitoring have been
explored.
 Sampling campaign conducted in 2017 in
Nevada.
 use of additional multiparameter probes:
pH, oxygen concentration, turbidity, or
chlorophyll.

4. Methodology
 New approaches involving the use of unmanned aerial
vehicles (UAVs, or drones) for pit-lake monitoring have
been explored.
 Niskin sample bottles or HydraSleeves.
 UAV Niskin water-sampling-> emergency release mechanism
 HydraSleeve approach-> No emergency release mechanism.

5. Procedure Steps
 Multi-parameter sonde deployment
 Micro diver procedure
 Water-quality sample collection
 Quality assurance evaluation

8. Results
 Water-sampling flight times varied from 5 to 8 min
each.
 Rapid identification of distinct hydrogeochemical
layers.

9. Implications and Future works
 acceptable for regulatory procedures
 identification of airspace restrictions
