A new study finds that underground water in the U.S. is being “slaked” by groundwater extraction.
In the study published online in the journal Environmental Science & Technology, researchers at the University of Pennsylvania and the University at Buffalo found that the underground water supplies of the U,S.
have become “frequent, concentrated, and rapid” as of last year.
“The current situation of overproduction of groundwater in the United States, particularly in the West, has created a situation in which groundwater aquifers are becoming increasingly depleted,” the researchers write.
A lack of underground water resources in the Southwest is a major contributor to groundwater depletion, the researchers note.
Water shortages in the state of Arizona, New Mexico, and New York are also contributing to groundwater shortages.
The report is the first to examine the water supply for the U in the continental United States.
While the study found a decline in underground groundwater supply in the last three years, the authors did not specify how much underground water was being tapped.
They did not address whether the water was extracted, whether it was treated or if it was recycled.
As a result, the study did not include groundwater rates or groundwater quality.
But water quality and extraction rates have remained relatively stable in the past decade.
Water quality and extract rates have increased, the report notes.
The authors also found that underground groundwater extraction has become more efficient in the recent years.
For example, in 2010, groundwater extraction accounted for around 5 percent of the total extraction rate.
In 2014, that figure rose to 10 percent.
But the rate of extraction has been falling for decades, from an average of 13.5 percent in 1975 to less than 6 percent in 2015.
The study also found a significant increase in groundwater rates during the last decade.
“In some areas, groundwater rates increased from 4.8 to 12.4 percent per year, and in others, rates increased by over 100 percent in the years 1990 through 2016,” the report states.
It says that the amount of groundwater extraction varies from region to region and that the rate and quantity of extraction varies across the country.
Despite a decrease in extraction rates, the amount and types of groundwater resources that are being used have remained constant in recent years, according to the report.
Dr. Daniel D. Smith, the lead author of the study, said in a statement that the findings are important because “it indicates that a change in groundwater management is taking place in the landscape.”
“The trend in groundwater extraction rates and quality in the region, as well as the fact that groundwater rates are increasing at a faster rate, indicates that water quality in many areas is being used more effectively and that extraction is being more efficient than it was before,” he said.
Smith said the findings “indicate that water extraction is becoming more efficient and that groundwater is being re-used at a higher rate.”
In the future, he said, groundwater management can be based on water-quality monitoring, water quality control and waste management.
The researchers found that groundwater extraction and the amount extracted increased in the areas where the water quality was better.
In some places, they found, extraction rates were increased by more than 200 percent.
In many areas, they reported that groundwater was being reused at a rate of more than 2,000 cubic feet per second.
