The Berkey is a great filter, but its not a purifier. It'll remove cysts, and so forth but cannot treat water for viruses, etc.

For a well I recommend a three step filtration system:

Sediment filtration followed by activated charcoal and then UV light.

If a viral issue is a concern the fourth step would be chlorination.
