Final answer:
A possible negative effect of building the pumping station according to the Mattaponi Indians is the disruption of the natural water habitat and ecology.
Step-by-step explanation:
Building a pumping station can have various effects according to different contexts, but in the case of the Mattaponi Indians, a possible negative effect of building the pumping station could be the disruption of the natural water habitat and ecology.
For example, the construction of a pumping station may involve altering the flow characteristics, water temperatures, chemistry, and silt loads of the river. These changes can have significant impacts on the local ecosystem and the physical characteristics of the river both upstream and downstream.
Therefore, the pumping station could potentially lead to the loss of natural wildlife habitat, changes in aquatic species population, and other disruptions to the Mattaponi Indians' way of life that is closely connected to the rivers and lakes in their region.
