Correspondence analysis of water quality data: Implications for fauna deaths at Stillwater Lakes, Nevada
- 52 Downloads
Over the last 2 years, more than seven million fish and 16,000 birds have died from drought-induced disease and suspected poisoning at Stillwater Lakes, Nevada. Correspondence analysis of water samples taken in June and September 1986, from lakes and reservoirs near Stillwater Lakes and four background lakes/reservoirs (not associated with fauna disease and death), is attempted to investigate the correlation among sites associated with fauna deaths. This analysis identifies high correlation between some Stillwater Lakes sites and boron. A correlation between boron and arsenic is also identified. Leaching and transport of toxins to the Stillwater Lakes system is one hypothesis to explain the wildlife deaths. Other hypotheses include the direct introduction of toxins by groundwater associated with geothermal activity. A natural cause for the wildlife deaths is also suggested, a cause not associated with the introduction of toxins.
