A complete LNAPL monitoring and recovery record combining impacted stratigraphy, graphical recovery-well construction, water and product interfaces, apparent product thickness, product identification, recovery method and volume, observations, disposition, and field QA/QC.
RW-01 LNAPL Monitoring and Recovery Well documents a 30 ft installation at a former bulk fuel terminal in Kitchener, Ontario. The 2 in PVC well has a 10-25 ft screen, a 25-27 ft sump, a silica-sand filter pack, bentonite and grout seals, and a flush-mount completion.
The validation report records Warnings status, 89% completeness, Good quality, an 80% confidence score, one warning, and no errors.
The measured 1.7 ft apparent product thickness is the difference between the 10.6 ft water interface and the 8.9 ft product interface. It is a well measurement and should not be interpreted directly as formation-wide LNAPL saturation or recoverable product volume.
The baseline event identifies amber, weathered gasoline with strong petroleum odour and sheen. A disposable bailer recovered 6.4 L before a passive skimmer was installed. Footer records preserve the reference datum, interface method, equipment check, recovery total, product disposition, and confirmation that no DNAPL was detected in the sump.
WinLoG reports one environmental cross-check warning at 9.75 ft: VOC=0 is inconsistent with the recorded strong petroleum odour. The record has no validation errors, but the reviewer should verify whether VOC screening applies to this recovery event, confirm the instrument result and units, or document why the product observation is valid without a corresponding VOC value.
Download the files individually. The XML template and completed log can be imported into WinLoG Version 6 and customized for LNAPL or DNAPL monitoring, recovery systems, interface gauging, remediation programs, and repeated monitoring rounds.
Documents product occurrence, well construction, interface gauging, recovery activities, field observations, and remediation-system decisions.
Supports bailer, skimmer and pumping programs with recorded recovery volumes, equipment details, product disposition, and secure well completion.
Provides aligned review of lithology, screened interval, water and product depths, thickness calculations, product observations, instrument checks, and recovery records.
WinLoG templates can be adapted for company standards and site-specific monitoring or recovery programs. Headers, construction columns, interface measurements, product types, recovery methods, volumes, observations, disposition fields, and validation rules can all be customized.
