Soil, groundwater and seawater testing

We sample soil, groundwater and seawater, have them analysed by licensed laboratories and explain what the results mean for your project.

Overview

Soil and water results decide a lot on a project: whether dewatering water can be discharged, whether soil counts as polluted, and what remediation a site needs. Soil counts as polluted when it exceeds the standards for its grain size and land use.

We plan the sampling, collect the samples to recognised methods and compare the results with the standards that apply.

In brief, from our library

You must inform NCEC as soon as soil pollution is detected, and failing to do so carries 10,000 to 1,000,000 riyals. Soil counts as polluted when it exceeds the Appendix 1 standards for its grain size and land use. A remediation plan prepared by an NCEC licensed service provider must be submitted within 10 working days, and NCEC decides within 10 working days. Starting the clean-up before NCEC approves the plan is itself a violation.Executive Regulation for the Prevention and Remediation of Soil Pollution

When you need it

  • You need to discharge dewatering water and must show its quality.Aqueous reg.
  • You suspect or have found contaminated soil. NCEC must be told as soon as soil pollution is detected.Soil reg.
  • You are buying, selling or closing a site and need its condition on record.

What we deliver

  • Soil samplingSurface and borehole samples.
  • Groundwater samplingFrom wells and dewatering systems.
  • Seawater and sedimentFor coastal and marine works.
  • Laboratory analysisThrough licensed laboratories.
  • Interpretation reportResults set against the applicable standards, with next steps.

How we work

  1. Plan

    Sampling locations and parameters from the site history and the question to answer.

  2. Sample

    Collected and preserved to recognised methods.

  3. Analyse

    Licensed laboratory analysis.

  4. Explain

    What the results mean, and what you need to do next.
