TMDL product: source and loading characterization, description of river and biotransformation processes, development of conceptual model linking land and water sources
Numeric Targets: The Desired Future Condition:

Status:

The desired future condition is restoration of all beneficial uses within the Guadalupe watershed. This involves limiting the amount of mercury entering the system and limiting the amount of mercury subject to transformation and bioaccumulation. This will result in lower fish tissue concentrations and the attainment of water quality objectives. There currently is no numeric target that ensures the desired future condition. The final product of this process may be best management practices (BMPs), numeric targets and load allocations, or a combination of these that apply to all known sources of mercury in the system.
