Thanks, EdithX. From the article you listed by link, I would like to focus on one quote:
"Mr. Bartell’s biggest fear is that the mine will consume the water that keeps his cattle alive. The company has said the mine will consume 3,224 gallons per minute. That could cause the water table to drop on land Mr. Bartell owns by an estimated 12 feet, according to a Lithium Americas consultant."
Addressing only the question of a fall in the water table, treating water quality as a separate issue, I don't see any merit to Mr, Bartell's professed concern over a 12 foot drop in the water table. The more important, by far, question is whether or not the mining activities proposed at Thacker Pass would, indeed, have a significant adverse effect on the quality of the water supplies in that area of Humboldt County, Nevada. That is the important issue that LAC will have to address if it is concerned about asuaging the political and economic concerns of government regulators and of local ranchers and farmers.
Some examples of ground water table situations can be quickly gleaned from data provided at the following web site:
USGS.gov | Science for a changing world
A monitored site not far from Thacker Pass and in Humbold County Nevada, for instance ( Site Station # 413300117494001 ) had a ground to water table depth of 100 feet in 1976 and in March of this year, 2021, that same ground to water table depth was 132 feet.
Taking just two other USGS measurement sites from dry areas of the United States as examples:
Lamb County, Texas, Hydrological Unit code 12050002 reported a ground to water table depth of 149 feet in 2019.
Texas County, Oklahoma, USGS Site Station # 363033101440701, had a ground to water table depth of 203 feet in 1981 as opposed to a ground to water table depth of 236 feet in 2017, the last year reported in the data from the USGS.
The importance of ranching and farming in Lamb County, Texas is documented in the following link:
TSHA | Lamb County (tshaonline.org)
The importance of ranching and farming in Texas County, Oklahoma is documented in the following link:
Texas County, Oklahoma was the #1 producer for livestock and crops for the entire state of Oklahoma, even though its ground to water table depth was 104 feet deeper than the present ground to water table depth in Humboldt County, Nevada.
The point being that with modern irrigation well technology there is no reason to suspect that an additional 12 feet depth of ground to water table distance in Humboldt County, Nevada should doom ranchers and farmers to an unsuprotable lifestyle as speculated by only a 12 foot drop in water table.
The key argument for both Nevada Lithium/LAC and for the farmers and ranchers of Hubmoldt County, Nevada has nothing to do with a possible 12 foot drop in water table. The focus has to be on water quality. That is the overiding issue, not a drop in water table. JMO Okiedo
