Texas Railroad Commission says there’s enough water for Eagle Ford fracking

According to http://www.rigzone.com/news/article.asp?a_id=114624&hmpn=1

But check the math. The figures below come from the article.

— 540,000 acre feet in the aquifer when the fracking began.

— 30,000 acre feet per year used by fracking at peak demand.

— fracking supposedly accounts for only 6% of total aquifer usage. Agriculture takes 65%.

This implies that the entire aquifer would be consumed within a few years.

Even if the frack water amounted to 25% of water usage, the aquifer would be gone in under five years. I have seen claims of up to 40% frack water usage in S. Texas — if that’s true, and the other figures are true, the aquifer would be gone in seven or eight years.

In any case, something’s not adding up here.
