Once Activities have been commenced and gas readings taken, water level information can be entered into the Water Levels tab or the Water Level Form. Select the tab.
For each filtered location create a dip reading as follows:
1)Select the location at which the measurement is being made then:
a.Select the date to ‘create’ a dip entry. This will also enter the time (so do this at the time the dip is measured) and Must Fill fields will be highlighted in red. Then for each field enter as follows:
b.Select the dip meter code from the drop down
c.Enter the measured depth to water below the datum (or elevation to water if above the datum). This is a MUST FILL field where a measurement is made but is not highlighted in red. All measurements MUST be in metres. If there should be observations about the reliability of the depth to water measurement enter a comment into the Remark field. Note: The Dip field may contain measurements of water level both above and below datum, the direction is recorded in the Dip or Elevation field described below
d.In the Dip or Elevation select either Dip where the measurement is below the datum (e.g. in a borehole) or Elevation if the measurement is above the datum (e.g. on a gauge board)
e.Note that the column headed Historical Range will be populated once the date is entered. This is a statistical range of acceptable values based on previous readings. If you enter a dip value outside of this range, the Dip column header will change colour to a red/orange, and floating tool tip stating “Warning: The result is outside the baseline range”. If you enter a reading giving rise to this warning, please repeat the dip, check that the first entry was correct or amend if not. If the warning persists after the checks, please add a Remark stating that the dip and entry have been double checked and are confirmed as correct. NOTE: While the warning remains the record will be shown as incomplete until it is saved and then reopened. This is required to ensure that warnings are not missed. Be aware that warnings that were shown during the original population of the EDGE EDD will no longer be visible after the file is closed and then reopened.
f.If the borehole is dry check the box in the Dry Y/N column, then leave Dip empty and put the plumb depth into the Plumb (m) column.
g.Enter the measured depth of the well below the datum into the Plumb (m) column. This is a MUST FILL field where a measurement is made although it is not highlighted in red. If there should be observations about the reliability of the depth of the well measurement enter a comment into the Remark field.
h.For surface water levels where there is no plumb reading to record, for example where a lake level is recorded as a dip below top of stake, or where a gauge board reading is entered, the plumb value should be set to 0 (zero).
i.GAUGE BOARD NOTE: If the water level is BELOW the zero point on the gauge board no value should be entered in the dip column. It should be entered as DRY – with a tick in the Dry column. If the water level is ABOVE the top of the gauge board, no value should be entered in the dip column and it should have a Qualifier of UW for underwater and Qualifer Note of underwater.
j.Select from the drop down list the type of instrument being used. Standard dip tapes would be those plastic coated tapes most commonly used. If a different type is being used please record it here. Where artesian conditions are being measured, i.e. water levels above the top of a sealed cover, a pressure gauge should be used to measure the head above the cover. In this case the instrument type should be recorded as Pressure Gauge. ARTESIAN CONDITION NOTE: This is an elevation above the datum so the DIP/ELEVATION field should be set to ELEVATION
k.NOTE: In boreholes where the water level can be artesian but is not always so, it is important to check whether it is artesian by opening the dipping port/sampling tube slowly to see if the water level comes up into it, if it doesn’t then the water level reading should be a DIP. If the pressure gauge is used but it gives a negative number, this is incorrect and a DIP should be measured.
l.Select your name from the drop down list in the Technician column
m.Use the Remark field to enter any comment about the measurement made or attempted that will help someone interpreting the information submitted.
n.Where a dip cannot be made (e.g. where the borehole cannot be found or accessed), leave the Dip and plumb blank and the Dry Y/N column unchecked, then select a Qualifier from the drop down list. Enter a description of the reason a dip could not be obtained into the Qualifier Note field. This should ONLY be used where a Qualifier has been entered in the Qualifier field.
o.In boreholes where hydrocarbon contamination is present an interface meter is used to measure the depth to the water level and to the interface with the hydrocarbon. LNAPL is a Light Non Aqueous Phase Liquid, and being light will float on water. The LNAPL field is used to record to depth to top of the hydrocarbon floating on the water. The depth the water interface below the LNAPL must be recorded as usual in the Dip field. Note: measurement depths must be in metres
p.Where the hydrocarbon is denser that water it will be found at the base of the water column. These liquids are Dense Non Aqueous Phase Liquids (DNAPL). Where a DNAPL exists in a borehole, the interface meter is used to measure the depth to water in the usual way, and entered in the Dip field, and the depth to the water/DNAPL interface in the Depth to DNAPL field. Again, all measurements must be in metres.
q.The Task Code is provided in the last column for information
r.When all the required data have been entered the Alerts column will be empty. If there are remaining must fill fields to be filled there will be a red number in this column. BUT please do not forget that MUST FILL fields such as Dip and Plumb must be populated where a reading has been made,, and Qualifier and Qualifier Note where a reading cannot be made.
