 Students from the University of New Mexico, in collaboration with the students from New Mexico Tech, are studying the water chemistry in the same area. With Dr. Crossie as their mentor, they have installed an additional 50 groundwater wells to measure the changes that occur between the surface water and groundwater in 30-minute intervals. Researchers are sampling for phosphorus and nitrogen as nutrients in the system and comparing pH and dissolved oxygen levels in the hypereic zone of the stream. The hypereic zone, as we can see in this diagram, is the interface or border between the surface water and the groundwater. This area has the greatest diversity of organisms that will be utilizing nutrients as they weave their way in and out of the surface water and the groundwater. Preliminary results are showing a very tight connection between precipitation events and spikes in both nitrogen and phosphorus in both the groundwater and surface water.
