Where the roster is filed, and where the work happens
These records are organised by the address on the licence, and that address is not a service area. A Delaware licence is granted by Delaware DNREC and is valid across the state — the county tells you where the business is, not the limit of where they will go.
In practice a rural county showing two licensed systems inspectors is rarely the real choice set. Every county page here lists its neighbours for exactly that reason.
