'Verseuchen' (to contaminate) is an inseparable verb. It is derived from the noun 'die Seuche' (an infectious disease). The prefix 'ver-' describes here a process that changes something negatively—so, to cover something 'with a plague.'
Die Fabrik hat den Fluss mit Chemikalien verseucht.
The factory contaminated the river with chemicals.
The verb is often used in the passive to describe the state, e.g. 'Das Wasser ist verseucht' (the water is contaminated). If the substance causing the contamination is named, you use the preposition 'mit' (+ dative).
Der Acker wurde mit Pestiziden verseucht.
The field was contaminated with pesticides.
You can recognize the meaning from the object: if it is something physical like 'Wasser' (water), 'Boden' (soil), or 'Lebensmittel' (food), the literal meaning is intended. With abstract nouns like 'Atmosphäre' (atmosphere), 'Vertrauen' (trust), or 'Gesellschaft' (society), the figurative meaning is intended.
Ein Tankerunglück verseuchte die Küste mit Öl.
A tanker accident contaminated the coast with oil.
In the figurative meaning, 'verseuchen' (to poison) is often combined with abstract concepts. Typical phrases are 'die Atmosphäre verseuchen' (to poison the atmosphere), 'das politische Klima verseuchen' (to poison the political climate), or 'das Denken verseuchen' (to poison people's thinking).
