The phrase "an observation well" is correct and usable in written English.
It can be used in contexts related to environmental science, hydrology, or geology, referring to a well used for monitoring groundwater levels or quality.
Example: "The researchers installed an observation well to collect data on the water table fluctuations over time."
Alternatives: "monitoring well" or "test well".
The water/DNAPL interface elevation at both the pumping well and an observation well was recorded.
Measurements were made of the ¹³CO₂ isotopic signature of gas exhaust from an observation well and two surface fissures.
The wellbore storage must be considered for a pumping test without an observation well (single-well test).
In a cross-well pumping test, measured responses to oscillatory pumping tests consist of the amplitude and phase delay of pressure changes at an observation well.
In order to improve understanding of the local water cycle and contamination dynamics in the aquifer beneath the city, a down gradient spring and an observation well were chosen to identify contaminant occurrence and loads.
The existing theory, which requires single sized horizontal fractures, is accurately calibrated by slug test data from three uncased bedrock boreholes in the Dedham Granite and an observation well screened just below the contact surface with a till drumlin.
Conforming 3-D images from two different algorithms support earlier hydrological investigations, indicating a conduit system where flow velocity variations lead to a circumvention of a close observation well and an onset of increased CO2 saturation downgradient from this well.
According to high-resolution DO time series measured in the Thur River (NE-Switzerland) and an adjacent observation well, the DO consumption rate appears to depend on river temperature and discharge.
This is an interesting observation, well supported by the phylogenetic analysis presented, that leads the authors to hypothesize a key role of this enzyme for the adaptation of plants to land.
As part of the project, an existing wellbore within the study area was used as a dedicated observation well.
Additional pressure measurements from a passive observation well would reduce the uncertainty in the Sgr estimate.
