1. A method of mitigating corrosion and erosion in an aircraft engine, comprising:
receiving a concentration of contaminants contained within a sample of an environmental medium ingested by the aircraft engine, including receiving the concentration of the contaminants contained within a container containing the sample, the container fluidly connectable to a drain port of the aircraft engine;
determining a frequency of corrosion and erosion mitigation actions based on the concentration of the contaminants; and
instructing a performance of the corrosion and erosion mitigation actions at the frequency.
