We need your help !! 

It is our responsibility as good neighbors and friends to be sure that we take an active interest/concern in our water Aquifers.  Seth Feinstein, your Homeowners Association President, has represented  BTRHOA in our community concerns in this area.

He attended a public hearing in Castle Rock to voice the BTRHOA concerns over the Timber Pointe Development that is working through the approval process in Douglas County. We have sent in a referral response to the planning and  community development department and at our last BTRHOA board meeting, the board requested that Seth pursue our concerns over the water wells in this project. 

We as citizens and homeowners need to be concerned on the impact of this Timber Pointe project utilizing the Upper Dawson Aquifer..... we need your assistance....your information and most of all your support.  We need any aquifer water level data or information that any of you might have to assist our quest to keep developers out of Upper Dawson.  We are looking for any volunteers to assist and participate in our water research committee. We have a very limited number of members in this committee and we need your help now before it's to late !!! 

If you would to participate or have information to assist us please e-mail Seth Feinstein at:  president@btrhoa.com

Thank you !!

 

Here's some useful information about Aquifers.......

What Is an Aquifer?
 

One of our most valuable resources is the water beneath our feet. Most of the time you can't even see it, and you may not even know it is there. Water (not groundwater) is held by molecular attraction and surrounds the surfaces of rock particles.

Different kinds of rocks have different porosity and permeability characteristics. Because of this, water does not move around the same way in all rocks. When water-bearing rocks readily transmit water to wells and springs, they are called aquifers. Wells can be drilled into the aquifers and water can be pumped out. Precipitation eventually adds water into the porous rock of the aquifer, which is known as recharging. The rate of recharge is not the same for all aquifers, though, and that must be considered when pumping water from a well. Pumping too much water too fast can draw down the water in an aquifer and may eventually cause a well to yield less and less water or even run dry. In fact, pumping your well too fast can even cause your neighbor's well to run dry if you both are pumping from the same aquifer.

Sometimes the porous rock layers become tilted in the Earth. There might be a confining layer of less porous rock both above and below the porous layer. This is an example of a confined aquifer. In this case, the rocks surrounding the aquifer confine the pressure in the porous rock and its water. If a well is drilled into the "pressurized" aquifer, the internal pressure might (depending on the ability of the rock to transport water) be enough to push the water up the well and up to the surface without the aid of a pump. Water can even flow completely out of the well. This type is called an artesian well. The pressure of water from an artesian well can be quite dramatic!

Some water trivia facts are available at http://www.epa.gov/ogwdw/kids/trivia.pdf.

An information sheet entitled "Water Facts of Life" can be found at http://www.epa.gov/ogwdw/kids/facts.pdf.

A fact sheet, called "Be Hydro-Logical," that gives suggestions for how to save water is available at http://www.epa.gov/ogwdw/kids/logical.pdf.



Aquifer Vocabulary
(From Perdue University)

 

Artesian Aquifer -- an aquifer that has pressure built up inside. This pressure is the result of the recharge area of the aquifer being at a higher level than the rest of the aquifer region. The force of gravity pulls the higher water down, which creates extra pressure inside the aquifer. This is why artesian wells flow by themselves; the pressure forces the water out of the well.

Confining Bed -- a layer of ground that resists water penetration. This layer is typically finer textured and denser than the above layers of soil. Confining beds can keep water from seeping to unreachable depths but can also prevent water from reaching aquifers.

Consolidated Rock -- rock that contains very few holes or cracks for water to get through. An example of unconsolidated rock is gravel. Consolidated rock can serve as a confining bed.

Flowing Artesian Well -- a well that has penetrated into an artesian aquifer. Artesian aquifers have pressure built up within themselves. This pressure results from a portion of the aquifer being at a higher elevation as shown in the figure. The pressure is released when a well is bored into it. This causes the well to flow spontaneously.

Nonflowing Artesian Well -- a nonflowing artesian well occurs when the pressure is not great enough to force the water out of the well. In this diagram, this is apparent because the flowing artesian well is at a lower elevation than the non-flowing artesian well

Recharge Area -- an area that allows water to enter the aquifer. It is particularly vulnerable to any pollutants that could be in the water. Also, if pavement is constructed over the recharge area, less water can enter the aquifer. This could mean a water shortage to those people using the groundwater from the aquifer.

Spring -- occurs when the water table is higher than the ground surface. Pressure forces the water out of the land at a weak point that creates the spring.

Surface Water Stream or Pond -- caused by a high water table. Also, a high water table can result from a stream and pond in that area.

Water Table -- the level at which the water stays. It is the very top of the zone of saturation. A few centimeters above this level water can also be found due to capillary action. In the presence of a pumping well, the water table will drop around the well. This is called drawdown. Under some conditions, a perched water table may exist. This occurs when the water percolation is interrupted by another confining layer above the "main" one.

Water Table Aquifer -- an aquifer that supports the water table. The top limit to this aquifer is the water table itself.

Water Table Well -- a water table well is a well that only extends down into the water table aquifer.
