E. coli in the exterior environment

OK, so the sewage system backs up and you have some severe sewage issues outside your home or apartment... what do you do? Well, I recently looked at an apartment unit where this happened and the interior samples all were negative for E. coli, but I found it in the exterior soil., I have no choice but to recommend removal of at least two (2) inches of soil and then treatment with JYMRSA. This is a potential lawsuit so I have nothing further to say... Eric out!
