摘要：
Groundwater monitoring well is crucial to observe aquifer status. Well cluster and nested well are usually employed to measure the multi-depth discrete aquifer status (e.g. groundwater level). These two types of wells work well in the field, but the construction of these wells is usually costly, time-consuming, and environmentally unfriendly. To address these issues, the multilevel well system (MLMS) based on the packer and electronic sensors has developed. However, these electronic MLMS are costly and take the disadvantage of waterproof, signal loss, power supply, etc. To overcome these issues, this study employs FBG technology to develop a new MLMS to observe the discrete aquifer status. To examine the capability of the developed MLMS, we have installed the MLMS in several selected fully-penetrated wells in a contaminated site to measure the head variations caused by several sequential remediation-agent injection events during 2018-2019. The collected head observations are employed to delineate the spatial distribution of the aquifer parameter fields based on the successive linear estimator. The results show that the MLMS successfully measures the multi-depth discrete head variations from the existing fully-penetrated wells. The comparison between the 2018 and 2019 aquifer parameter fields indicates that the aquifer parameter structure varies with time due to the precipitation from remediation-agent injection and dissolution caused by some possible biochemical reactions, which need to be further studied.
