Site-specific guideline values — without spreadsheets
Calculate guideline values per report 5976, import lab data from ALS and Eurofins, and compare measured concentrations against calculated guidelines — in a web-based platform.
Calculate
Site-specific guideline values across all exposure pathways — health, soil ecosystem, groundwater and surface water. Based on Swedish EPA report 5976.
Import
Lab reports from ALS and Eurofins are imported automatically from Excel. LOQ handling and sum parameters included.
Compare
Measured concentrations against calculated guideline values, per sample point and substance. Color-coded overview showing exceedances at a glance.
How it works
Create a project
For your site or property. Invite colleagues as needed.
Set scenario parameters
Land use, soil properties, building type and hydrogeology.
Import lab report
Directly from Excel (ALS/Eurofins), or enter concentrations manually.
Get guideline values and comparisons
With full traceability. Export as PDF for regulatory submissions.
Technical documentation
Methodology & Calculation Model
Naturvårdsverket Rapport 5976
The application strictly follows the Swedish EPA report 5976. Calculations are performed in real-time based on your scenario parameters.
Exposure Pathways
Calculations cover ingestion, dermal contact, inhalation (dust/vapor), and protection of groundwater/surface water/soil eco-systems.
- Soil ingestion, dermal contact, dust inhalation
- Inhalation of vapors (indoor & outdoor)
- Drinking water intake
- Protection of soil ecosystem
- Protection of groundwater
- Protection of surface water
The Limiting Value
The final guideline value is the lowest of Health risks, Environmental risks, and Physical constraints.
Lab Data Handling
Import & Analys
The engine parses raw data (ALS, Eurofins) and normalizes it.
LOQ Handling
Values below LOQ are typically treated as 50% of the limit during aggregation, ensuring consistent statistical treatment.
Sum Parameters
Aggregates (e.g., PAH-L/M/H) are calculated from individual components if not provided explicitly by the lab.
Workflow & Structure
Projekt & Rapporter
Scenarios vs Projects
A Project represents a Site. Scenarios represent different parameter sets (e.g., "Sensitive Land Use" vs "Commercial").
Traceability
Reports are timestamped and snapshot the input parameters used, ensuring full auditability.
