Groundwater age dating
With over 20 years of remediation projects under our belt we know that a one size remediation technique does not work on every site.On any given property requiring remediation, a variety of approaches should be considered so that both the cost and effectiveness of each approach can be weighed against the project objectives.
Rosales/Journal)Copyright © 2017 Albuquerque Journal SANTA TERESA – Deep underground, beneath the 18-foot steel wall that divides parts of the U. and Mexico border, the aquifer upon which both sides depend pays the barrier no mind.
The century-old international agreement that governs every drop of Rio Grande surface water doesn’t apply to the water that courses underground.
The binational aquifer – called the Mesilla Bolson on the U. side and Conejos Medanos on the Mexican side – is the freshwater source upon which southern New Mexico has anchored its hopes for its own economic future.
The older a sample is, the less (the period of time after which half of a given sample will have decayed) is about 5,730 years, the oldest dates that can be reliably measured by this process date to around 50,000 years ago, although special preparation methods occasionally permit accurate analysis of older samples.
The idea behind radiocarbon dating is straightforward, but years of work were required to develop the technique to the point where accurate dates could be obtained.
