In May, San Antonians will have the opportunity to vote on whether to continue an aquifer protection program that collects one-eighth of a cent sales tax. After meeting on Wednesday for an initial discussion on the matter, on Thursday, the San Antonio City Council unanimously approved what will be propositions 1 & 2 in the upcoming municipal election.

  On Thursday, the San Antonio City Council will decide whether to ask voters to renew a sales tax for aquifer protection and park maintenance. This one-eighth of a cent sales tax could potentially have a host of uses.  

At the moment, the City of San Antonio uses most of the money collected from the sales tax to buy property in the Edwards Aquifer Recharge zone, which replenishes the area’s water supply. The tax was first approved in 2000, and 133,000 acres have been purchased so far through this money. 

State lawmakers are considering a nearly $2.5 million plan to help answer a pressing question in some Texas communities: Why does the ground keep shaking?  

Experts Looking At Whether Fracking A Factor In Texas Quakes

Jan 9, 2015

Geophysicists are looking at whether hydraulic fracturing, generally known as fracking, might be one of the factors responsible for a number of quakes to hit Texas earlier this week. Fracking is a process through which liquid — generally chemicals and sand suspended in water — at very high pressure is blasted into wellbores to fracture the shale rock layers and release natural gas. Also this week, a study from the Bulletin of the Seismological Society of America linked dozens of earthquakes in Ohio in March 2014 to fracking in the area. A previous study in Oklahoma had linked the wastewater shot into deep disposal wells to a surge in quakes there.

People felt two small but noticeable earthquakes in the Dallas area Tuesday, with reports of shaking buildings and flickering lights. Some residents said they felt nothing; some worried about fracking; others joked about it all.

The first quake was measured at 3.5 magnitude, according to the U.S. Geological Survey, and the second was measured at 3.6. Both of them were centered about 3.5 miles east-northeast of Irving, just outside of Dallas.
