So to extrapolate from the tables, Giardia would behave like Entameba histolytica (ref. Basic Clinical Parasitology, Brown & Neva), and Hep A would behave as an enteric virus (Essentials of Microbiology, Cano & Colome).

According to the CDC, Giardia cysts can be infective "several months" in the soil. So if you let the compost age, it should be fine. Now that there is a vaccine for hepatitis A, the outbreaks are few and far between. The virus is quite durable in water and sewage, but a thermophilic compost pile should do most of them in. Sorry I don't have hard data.

Hello Folks,
I am living in a progressive intentional community. We are beginning construction of a new neighborhood of eight households. We are pursuing a central humanure composting facility for the eight households. Some members of the larger community have questions about the lifespan of hepatitis A and giardia. These diseases were a problem in our community decades ago during the outhouse days. Does anyone know of specific data regarding the survivability of hepatitis A and Giardia in a well managed humanure compost pile?
