From the borehole to the report, with each depth recorded
Investigation and monitoring of contaminated sites with depth sampling, custody records, and soil and groundwater results compared with the guideline values the laboratory registers.
Who it is for
For laboratories and consultancies that work with soil and groundwater. Besides analyzing the sample, you need to record where it came from, from which depth and which value it was compared with.
Fuel stations.
BTEX and TPH in soil and groundwater, with each sample linked to the boring point and the depth.
Industries with historical contamination.
Metals, PAHs and other compounds evaluated by matrix, with the profile recorded in the field.
Consultancies with periodic monitoring.
Monitoring wells with recurring sampling linked to the contract. The next campaign is generated on the plan's date.
Remediation follow-up.
Each campaign records the same point over time, which helps follow how concentrations change.
Each sample comes in with its depth recorded, even with no signal.
The sampler heads out with the route and records point, depth and profile in the app without a connection. The sample stays linked to the custody records, from the borehole to the report.
- Depth recorded at the point
- App with offline mode and GPS, sending on reconnect
- Custody records from field to report
Guideline values: the laboratory registers, the system compares
Gerencialab does not include preloaded guideline values. The laboratory registers the values it uses, such as the CONAMA 420/2009 soil quality guideline values and the applicable state guideline values, by matrix and by land-use scenario. On entry, the system compares each result with the value registered for the service.
CONAMA 420/2009 as a registered criterion.
CONAMA Resolution 420/2009 covers soil quality guideline values and the management of contaminated sites. The laboratory registers the values it adopts and keeps the registry up to date.
State guideline values.
When the state has its own list, such as CETESB's in São Paulo, the laboratory registers the list it uses and checks the updates published by the agency.
One reference per land-use scenario.
Agricultural, residential and industrial scenarios may have different values for the same compound. The laboratory can register one reference per scenario and link it to the point's service.
Soil and groundwater kept apart.
Each matrix has its own set of values. The sample uses the reference linked to the service, which helps reduce table mix-ups.
Limits and their updates are maintained by the laboratory.
Site investigation and management, classification and the remediation decision are the technical responsibility of the laboratory or consultancy. The system does not replace environmental licensing or the contaminated-site management process with the agency.
Technical decisions, such as acceptance criteria, decision rules, method validation and release of results, belong to the laboratory. The system records and organizes these decisions.
The points that weigh most in an investigation
The system was designed around these points of the investigation routine.
Depth recorded with the sample.
The sampler records depth, point condition and profile in a configurable form, and the data stays linked to the sample up to the report.
Documented chain of custody.
Each sample records who collected, who received, who analyzed and when, from proposal to report.
Land-use scenario in the registry.
The same compound may have different values depending on the scenario. Registering by scenario helps reduce the risk of comparing against the wrong table.
Wells far from signal.
The sampler records point, water level, photos and data in the app without a connection. Sending happens when the connection returns.
How Gerencialab supports the work
From the borehole to the report, with less rework between steps.
Results above the registered value highlighted.
On entry, each compound is compared with the value registered for the service, and anything above it is highlighted for technical review.
Each depth recorded.
Registered points and forms with depth, profile, point condition and notes, with a history of what was entered.
Sampling with no internet at the point.
The app records the point with GPS, depth, photos and data and sends them later. Route notices via WhatsApp work when that integration is configured.
Labels and container history.
Each container comes in with a barcode or QR and has a history from intake to disposal.
The laboratory's signed report.
Configurable template with header and footer, variables filled in by the system, signature and PDF. Each template version is controlled.
Each sample has a history from proposal to report. During an audit or when the agency questions a point, the team looks up the result's history, including the depth and the reference used.
Each result compared with the value the laboratory registered.
Soil and groundwater come in with method and parameters by matrix. Each compound is compared with the guideline value registered for the service, and anything above it is highlighted.
- CONAMA 420/2009 values and state lists registered by the laboratory
- Comparison on entry, using the reference linked to the service
- Report signed by the technical manager

What exists today and where the limits are
Status of each feature mentioned on this page, for the current version of the system.
| Topic | Status | What exists today | Limit / laboratory responsibility |
|---|---|---|---|
| Regulations and limits | Depends on configuration | The laboratory registers regulations, matrices and maximum allowed values, and the system compares each result with the limits registered for the service. | Regulations are not preloaded. Registering, checking and updating limits are the laboratory's responsibility. |
| Sampling app with offline mode | Available | The app downloads sampling jobs, including PDFs, for work without internet. It records photos, the client's signature, GPS and checklist, and sends them in batches, with retries, when the connection returns. | Offline mode covers the operations confirmed in on-device testing. Validate your sampling flow in airplane mode during implementation. |
| Receipt and handling of samples | Available | Pre-receipt and technical inspection of samples with barcode scanning, unique identification and a history of the stages up to disposal. | Acceptance criteria, storage conditions and handling of deviations at receipt are defined by the laboratory. |
| Instrument result import | Via file import | Imports results from CSV, TXT, XLS and XLSX files and from ASTM E1394, HL7 v2, XML, JSON and fixed-width text formats. Files arrive through an agent installed at the laboratory that watches a folder, by manual upload or by webhook. | The system does not connect to the serial port or directly to the instrument. The ready-made import profiles are generic, with no reader specific to a manufacturer or model, and each instrument is configured and tested with the laboratory. |

Frequently asked questions
Are the CONAMA 420/2009 values and the state lists included in the system?
No. The system has a registry for values and regulations, and the laboratory enters the compounds and values by matrix and land-use scenario. Checking and updating them is up to the laboratory. During onboarding, our team helps build the registry.
How does the system handle the same result in different land-use scenarios?
The laboratory registers one reference per scenario (agricultural, residential, industrial) and links it to the point's service. The result is compared with the linked reference. Choosing the scenario is a technical decision of the laboratory or consultancy.
Can I record the depth of each sample?
Yes. Sampling uses configurable forms where the sampler records depth, profile, point condition and notes. The data stays linked to the sample up to the report.
How does the chain of custody work?
Each sample records who collected, who received, who analyzed and when, with a barcode or QR label and an audit trail. The team looks up that history when the agency or the audit asks.
Does the system decide whether the site needs remediation?
No. The system compares the result with the registered values and organizes the data by point and depth. Site investigation and management and the remediation decision are the technical responsibility of the laboratory or consultancy. The system does not replace environmental licensing.
Does it import instrument results?
Instrument results come in by file (CSV, TXT, XLS, XLSX, ASTM, HL7, XML, JSON or fixed-width text), through a local agent that watches a folder, by manual upload or by webhook. Each instrument is configured and tested with the laboratory. Continuous serial capture is not available in the current version.
