With regard to National Pipeline Mapping System drinking water data, all of the sources appear to be the same size – where does the data come from? How was the diameter/buffer from intakes determined?
Most of the drinking water data comes from state drinking water agencies and the Environmental Protection Agency. The drinking water USAs that are surface water intakes have a five mile buffer placed around their location. The ground water USAs have buffers that vary in size. These buffers are designated by the state’s source water protection program or their wellhead protection program and these buffer sizes vary from state to state.
