Usage tips
Technical term
'Fäkalien' (feces) is a technical term from biology, medicine, and environmental engineering. This word is hardly used in everyday language because it sounds very formal and scientific.
EXAMPLE
Bei der Wasseranalyse wurde eine hohe Konzentration von Fäkalien festgestellt.
During the water analysis, a high concentration of feces was detected.
Use in the plural
The word 'Fäkalien' (feces) is almost always used in the plural, even when only one type of excretion is meant. The singular form 'die Fäkalie' (a fecal matter item/excretion) is very rare and unusual.
EXAMPLE
Das Abwasser muss von Fäkalien gereinigt werden, bevor es in den Fluss geleitet wird.
The wastewater must be cleaned of feces before it is discharged into the river.
Typical context
The word 'Fäkalien' (feces) often appears in connection with 'Abwasser' (wastewater), 'Kläranlagen' (sewage treatment plants), 'Hygiene' (hygiene), and the 'Verschmutzung' (pollution) or 'Kontamination' (contamination) of water and soil.
EXAMPLE
Durch die Überschwemmung wurden Fäkalien in die Trinkwasserquellen gespült.
Due to the flooding, feces were washed into the drinking water sources.

Fäkalie vs Stuhl
chair / stool
'der Stuhl' and 'die Fäkalie' can both refer to human or animal excretions. 'Stuhl' is mainly a medical word for human feces, for example at the doctor’s office or during an examination. 'Fäkalien' is a more technical word and is almost always used in the plural. It is especially appropriate in texts about hygiene, biology, wastewater, or pollution. The words can be confusing because both sound factual and clinical. In a normal conversation with a doctor, 'Stuhl' is more natural; in technical or scientific contexts, people are more likely to say 'Fäkalien'.
