If you've been reading this blog for a while, you've been hearing (maybe more than you want) about our water issues here in Central Texas.
You know that we've been updating our water systems for several years. We installed this 1500-gallon emergency tank last spring (the photo was taken in April, when the grass was still green):
If it ever starts to rain again, we'll hook the tank up to the gutters. In the meantime, we've filled it from our well. It's mostly meant for emergency use: Bill has rigged a pump that will enable us to use it for firefighting, if that's ever necessary. But we have several producing pecan trees within easy hose distance of this tank, and we can use it for irrigating them. Previously, Bill irrigated the pecans from the creek, but that's been dry for nearly a year.
We've known for a couple of years that our current wells (there are three of them at Meadow Knoll, all drilled in the early-mid 1980s) are in trouble. The Trinity Aquifer that serves our area is depleting, which means that the older wells are too shallow to reach the new lower levels. Well drillers in our county have a long queue of replacement wells to drill--and they're all going to be between 50-100 feet deeper. We've been on the list for months, and finally TODAY! it's our turn.
The team got to work early this morning, expecting to drill to depth (not sure yet just what that will be) by the end of the day, then case the well tomorrow.
The county hydrologist is on the site, too. He's logging the well: that is, using an electronic sensor dropped down through the pipe string to make a record of the strata through which it's been drilled.These well logs (which weren't systematically kept for the earlier wells) add to the understanding of the geology and water resources of the area.
The images are read on a computer in the trailer the hydrologist towed onto the site. Please bear in mind that all this is happening in Texas while I'm sitting at my computer in New Mexico, posting the photos that Bill is emailing me. (I'm old enough to remember pasting a 3-cent stamp on my high school graduation announcement. I may never stop being thrilled by this instant communication.)
And here is the first water strike. Bill titled this photo "Looks Like We're Getting Somewhere." Of course, we're not there yet--that is, "there," at the right point in the aquifer, where we can count on good-tasting water, produced at a sustainable rate of over 10 gallons a minute. Well-drilling is still an art as well as a science, although probably less of an art than it used to be in the days of the dowsers.
Our current wells produce very slowly, just a few gallons a mnute. We're hoping this new, deeper well will give us more water for the vegetable garden and our trees. But that doesn't mean we'll waste it: we do conserve and recycle as much as possible. My main use: the vegetable garden. The only decorative plants I have left are herbs and natives that tolerate heat and drought--although even they struggled last summer, with months of 100+ temperatures.
Our situation is only one small example of the problems in this region. The drought may be only beginning, and there are no quick fixes or silver bullets. Rural folks who manage their own water supplies and live surrounded by the drought's visible impacts (dying trees, ranchers and farmers going out of business, recreational supplies drying up) are far more conscious of the issue. Urban residents will only catch on when they discover that their grassy lawns and swimming pools are no longer sustainable. Water availability will limit how much fracking can be done in some areas, such as the Eagle Ford Shale, where residents, farmers, and ranchers compete with the oil companies for what little water there is. And policy planners will have to stop playing political games and start making long-term plans for this endangered resource.
Meanwhile, we're happy that our well finally got to the top of the list, and that the drillers are finding water at the bottom. Believe me, we will treasure every drop of water it produces.
UPDATE: Sat Jan 7. Looks like we may get 8 gal/min tops from this well--a little hard to say yet, because the pump hasn't been installed. It's not going to be a gusher, but it will certainly be better than the current well, and good enough for the irrigation we need to do.
If you'd like to read more about the importance of our water resources, here are two very good books: When the Rivers Run Dry: Water: The Defining Crisis of the Twenty-First Century, by Fred Pearce (2007); and Cadillac Desert: The American West and Its Disappearing Water, by Mark Reisner (1993).
