Our method
The analyses we perform on soils as part of surveys to assess contaminated sites – be them intended for residential, public, or private green use (table 1, column A) or commercial/industrial use (table 1, column B) – assume a primary role as they affect upcoming reclamation works and the potential disposal of soil if it is found to be contaminated.
Marino deploys technicians during sampling and measurement processes to ensure the samples to be analysed are well represented and that the quality, accuracy, and timeliness of analytical processes are guaranteed at our lab. The contaminants ascertained are those provided for by Legislative Decree No. 152/06 and subsequent amendments, as shown below:
- Arsenic
- Mercury
- Zinc
- Cadmium
- Cobalt
- Nickel
- Lead
- Copper
- Tin
- Manganese
- Vanadium
- Selenium

- Aluminium
- Boron
- Hydrocarbons C>12
- PAHs
- Aromatic Sulfonic Acids
- Phosphorus Phytopharmaceuticals
- Total Organic Carbon
- Total Chromium
- Hexavalent chromium
- Soil oxidising power for Hexavalent Chromium

Sewage sludge analysis
Marino performs the chemical and microbiological analyses required to assess and verify compliance with Legislative Decree No. 99 of 27 January 1992 as amended, and specific regional regulations such as DGRC No.170 of 3 June 14 (for the Campania Region) concerning the use of sewage sludge in agriculture to make use of its fertilising and soil improving properties.
The characteristics of sludge as an index of the efficiency of the water purification process.
The characteristics of sludge to be used in biogas production processes, pursuant to Ministerial Decree of 5 February 1998.
