This is the case, for example, with chlorinated solvents.

Chlorinated solvents, or chlorinated aliphatic hydrocarbons, are used as solvents for the cleaning as well as for the extraction and the separation of certain products, they are also used as refrigerants (chlorofluorocarbon or CFC). They are widespread. Their presence in landfills of all types constitutes a risk of groundwater pollution because they are not retained by the clays. After percolation into the ground, groundwater near urban or industrial areas (industrial discharges) can be contaminated by these highly volatile pollutants. They are not degradable and tend to settle in the lower part of the water table.

If Beowulf represents the way Anglo-Saxons were, or what they wanted to become, then I believe they were fierce people. They were strong and brave (they managed to conquer the entire British isles) and they didn't falter when faced with dangers. They endured any hardships that they encountered and came out of their troubles strong, and created an entire nation of English people.This is similar to what happened in the epic poem - Beowulf was a hero who was strong and brave and managed to defeat the monster Grendel, just like the Anglo-Saxons managed to defeat their own enemies. Beowulf became a king and took care of his people, just like the Anglo-Saxons started a new group of people.
