A Few Thoughts on the E-Tunnel Discharge at Rainier Mesa, Nevada National Security Site
In reviewing the Quarterly Monitoring Reports assembled by Navarro for the Rainier Mesa E-Tunnel discharge for the past year (the “Navarro” data), Greg Raab of the Nevada Department of Environmental Proctection (NDEP) noticed a decreasing trend in the pH and was curious as to what was causing it. He noticed an upswing in the March 2016 data and speculated as to whether the trend would go up. Irene Farnham (Navarro) sent along the Navarro chemical and flow data from ETunnel, going back for some of the variables to 1997. Previously I was curious as to whether there was a trend in the discharge flow rates from E-Tunnel that corresponded to Greg Raab’s observations and comments about the decreasing trend in pH observed between 2015 and 2016. So, I plotted the two time series from the Navarro data over roughly the same time period that Greg looked at. There does not appear to be much of a correlation. (NB: The value of 7.1 for January 2016 differs from the value of ~6.55 in Greg’s data).
