Poorly managed solid waste disposal in the Sagarmatha National Park, Nepal, (SNP) is causing considerable degradation of major rivers and drinking water in the region. This research began as a study to: (1) identify sources of water contamination; (2) better understand the breadth of this problem; and (3) begin to develop technical solutions for resolving these problems. The remoteness of the study site and rugged terrain challenged the equipment used to collect and store samples and caused us to modify our protocols. Further, the complex interactions among natural resource management issues, increasing tourism, a struggling economy, climate change, and the risk of natural disasters (e.g., earthquakes) in the SNP triggered a change in our initial approach to the problem. We decided to broaden our research goals to include community-based resource management efforts designed to inform how resources are protected and governed in the SNP. Understanding communities, residents, and other stakeholder’s attitudes and perceptions of the social, economic, and environmental risks is necessary to help community leaders develop and sustain a useful governing framework to support water quality risk mitigation. This manuscript is an effort to communicate the evolving nature of our methodology over time and make a case for flexible research design, particularly in areas where geography, culture, and resource management potentially pose substantial challenges to traditional research methods. The methodology we eventually adopted is generalizable to similar remote mountainous regions around the globe.

In 2019, after almost a decade of working on water quality in the Himalayas, we submitted a proposal to Geoscientists Without Borders® (GWB) titled “Understanding high mountain aquifers to source drinking water in Sagarmatha National Park.” The project involves a combination of water-quality and quantity measurements, geologic mapping, and an electrical resistivity tomography survey. The goal of the project is to help two communities (Phortse and Lobuche within Sagarmatha National Park in Nepal) minimize their water vulnerability to climate change and earthquakes. The project team includes researchers and students from the United States and Nepal, as well as nongovernmental organizations, government agencies, and community councils. In the proposal, we identified physical health and altitude as the primary risks that could hinder the success of the project. Like everyone else in early 2019, we had no way to foresee the events of 2020, which would almost completely derail our project. Health has turned out to be the major hinderance. The irony of the global pandemic is how much it has impacted the work of the U.S.-based team and how little it has impacted the necessity of the project.

During the 2016 pre-monsoon dry season, we undertook a systematic study of water quality, specifically fecal contamination of drinking water, in the Khumbu Valley, Sagarmatha National Park (SNP, Mt. Everest region) and SNP buffer zone, Nepal. Our goal was to quantify physical parameters (temperature, pH, conductivity and total dissolved solids), and the presence of fecal coliforms (E. coli and total coliforms) in drinking water and drinking water sources (predominately groundwater-fed springs). This data set will function as a baseline for access to potable water and further monitoring. Sample sites were selected based on primary use as a drinking water and/or drinking water source for each community. In general, there is little correlation between and physical parameters however, there are very weak correlations between total coliform data and increasing temperature, and decreasing elevation and pH. There does, however, appear to be a correlation between population (including tourist numbers) and both E. coli and total coliforms. Our study clearly indicates that the presence of bacterial indicators of fecal pollution during the dry season. Samples from the more populated, lower altitude areas had higher levels of E. coli and coliform bacteria. Importantly, drinking water that was stored in tanks or transported long distances had a much higher incidence of E. coli and total coliforms suggesting that a change in water handling practices might have an important impact on drinking water quality and population health.

Downscaling future temperature projections to mountainous regions is vital for many applications, including ecological and water resource management. In this study, we demonstrate a method to downscale maximum temperatures to subkilometer resolutions using the Parameter-elevation Regression on Independent Slopes Model (PRISM). We evaluate the downscaling method with observations from a network of temperature sensors deployed along western and eastern slopes of Virginia’s Shenandoah National Park in the southern Appalachian Mountains. We find that the method overestimates mean July maximum temperatures by about 2°C (4°C) along the western (eastern) slopes. Based on this knowledge, we introduce corrections to generate maps of current and future maximum temperatures in the Shenandoah National Park.
