Monitoring the Hydraulic Performance of a Containment System with Significant Barometric Pressure Effects
Under certain circumstances, wells in unconfined aquifers can display significant water level fluctuations in response to changes in barometric pressure. This is illustrated by Hare and Morse (1997) at a site where a portion of the unconfined aquifer is isolated by a soil-bentonite cutoff wall and c...

This is illustrated by Hare and Morse (1997) at a site where a portion of the unconfined aquifer is isolated by a soil-bentonite cutoff wall and clay cap. A relief well located within the containment system displays water level fluctuations that mirror barometric pressure changes. Water levels fluctuated 0.37 m in response to barometric pressure changes of 2.87 centimeters mercury (cm-Hg), representing a barometric efficiency of 93.6%. As described in this paper, the short-term variability in water level elevations inside the containment system had to be considered to develop a reliable post-enhancement performance monitoring program. The approach that was ultimately selected involves correcting the water level elevations obtained in the relief well within the containment system for the effects of barometric pressure changes prior to comparison with the water level elevations in an observation well in the aquifer outside the system. The reliability of the post-enhancement performance monitoring program is improved further by simply requiring that any decision to enhance the containment system be based on the water level measurements obtained during two consecutive months. Using this approach, the probability that the containment system's performance will erroneously be deemed unacceptable is low. The post-enhancement performance monitoring program also requires no extra field work and does not involve any specialized equipment, which helps to keep operation and maintenance costs to a minimum. | ||

Monitoring the Hydraulic Performance of a Containment System with Significant Barometric Pressure Effects |
| abstract |
Under certain circumstances, wells in unconfined aquifers can display significant water level fluctuations in response to changes in barometric pressure. This is illustrated by Hare and Morse (1997) at a site where a portion of the unconfined aquifer is isolated by a soil-bentonite cutoff wall and clay cap. A relief well located within the containment system displays water level fluctuations that mirror barometric pressure changes. Water levels fluctuated 0.37 m in response to barometric pressure changes of 2.87 centimeters mercury (cm-Hg), representing a barometric efficiency of 93.6%. As described in this paper, the short-term variability in water level elevations inside the containment system had to be considered to develop a reliable post-enhancement performance monitoring program. The approach that was ultimately selected involves correcting the water level elevations obtained in the relief well within the containment system for the effects of barometric pressure changes prior to comparison with the water level elevations in an observation well in the aquifer outside the system. The reliability of the post-enhancement performance monitoring program is improved further by simply requiring that any decision to enhance the containment system be based on the water level measurements obtained during two consecutive months. Using this approach, the probability that the containment system's performance will erroneously be deemed unacceptable is low. The post-enhancement performance monitoring program also requires no extra field work and does not involve any specialized equipment, which helps to keep operation and maintenance costs to a minimum. |

Under certain circumstances, wells in unconfined aquifers can display significant water level fluctuations in response to changes in barometric pressure. This is illustrated by Hare and Morse (1997) at a site where a portion of the unconfined aquifer is isolated by a soil-bentonite cutoff wall and clay cap. A relief well located within the containment system displays water level fluctuations that mirror barometric pressure changes. Water levels fluctuated 0.37 m in response to barometric pressure changes of 2.87 centimeters mercury (cm-Hg), representing a barometric efficiency of 93.6%. As described in this paper, the short-term variability in water level elevations inside the containment system had to be considered to develop a reliable post-enhancement performance monitoring program. The approach that was ultimately selected involves correcting the water level elevations obtained in the relief well within the containment system for the effects of barometric pressure changes prior to comparison with the water level elevations in an observation well in the aquifer outside the system. The reliability of the post-enhancement performance monitoring program is improved further by simply requiring that any decision to enhance the containment system be based on the water level measurements obtained during two consecutive months.
