Efficient & compliant media testing

Data-led insight. Practical application.

 At Newtral, testing is about more than compliance, it’s about understanding the materials, conditions, and variables that directly impact long-term performance.

Alongside soil and media analysis for reed bed systems, we provide a wider range of environmental and agricultural testing services to support land management, material quality, and operational decision-making.

Testing & Analysis Services

Soil & Media Testing

Soil & Media Testing

Soil & Media Testing

We provide detailed analysis of soils and aggregate materials to ensure suitability for reed bed and constructed wetland applications.

Testing includes:

  • Particle size distribution 
  • Hydraulic conductivity 
  • Organic content 
  • Contamination screening 
  • Material grading and suitability 

Our approach helps reduce risk before installation and supports long-term system performance

Water Testing

Soil & Media Testing

Soil & Media Testing

 Water quality is a critical factor in environmental and treatment system performance.

We provide water testing services to support:

  • Reed bed and wetland monitoring 
  • Site investigations 
  • Compliance and performance checks 
  • Agricultural and environmental assessments 

Testing can include:

  • pH and conductivity 
  • Suspended solids 
  • Nutrient analysis 
  • Contamination indicators 
  • General water quality assessment

Agricultural Testing

Soil & Media Testing

Environmental Site Assessments

 We also support agricultural operations with targeted testing services designed to improve land and feed management.


Feed Testing

Analysis to assess feed quality, consistency, and nutritional performance.


Land & Soil Assessment

Testing to support:

  • Nutrient management 
  • Land suitability 
  • Soil health monitoring 
  • Agricultural planning and optimisation

Environmental Site Assessments

Environmental Site Assessments

Environmental Site Assessments

Our environmental experts conduct thorough site assessments to identify potential hazards and risks to the environment, and provide recommendations for remediation and management of contaminated sites.

Sustainability Consulting

Environmental Site Assessments

Sustainability Consulting

We provide sustainability consulting services to help your organization develop and implement sustainable practices and policies that promote environmental responsibility and social equity.

We work with recycling centres and partners across the UK who specialise in dealing with a variety of treatments to cover a wide range of contaminants.


Newtral also offers fast-tracked soil sample testing kits which allows testing for asbestos and other contaminant materials. If the tests are positive for contaminants Newtral can help with prompt removal and disposal. Otherwise, safe recycled soils can remain on site.


Poorly specified or untested media can lead to early clogging, uneven flow, and reduced treatment performance. Our approach ensures that every reed bed is built on a foundation designed for durability and efficiency.


We focus on:

  • Maintaining optimal flow through the system
  • Supporting healthy microbial and plant activity
  • Preventing premature failure and costly maintenance 

What We Test

Particle Size Distribution

We assess grading to ensure correct layering and flow characteristics. Proper sizing prevents blockages and supports consistent hydraulic behaviour..

Hydraulic Conductivity

We evaluate permeability to balance retention time and drainage. This is critical for achieving effective wastewater treatment.

pH and Chemical Stability

We ensure materials fall within optimal pH ranges and do not introduce harmful chemical reactions that could impact treatment processes.

Organic Content

Low organic content is essential to minimise clogging risk and maintain long-term system performance.

Nutrient Profile

We assess nitrogen, phosphorus, and potassium levels to support plant establishment without compromising treatment gradients.

Contaminant Screening

We test for heavy metals, hydrocarbons, and other pollutants to ensure safe and compliant operation.

Accurate testing. Practical insight. Reliable outcomes.
