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.
We provide detailed analysis of soils and aggregate materials to ensure suitability for reed bed and constructed wetland applications.
Testing includes:
Our approach helps reduce risk before installation and supports long-term system performance
Water quality is a critical factor in environmental and treatment system performance.
We provide water testing services to support:
Testing can include:
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:
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.
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:

We assess grading to ensure correct layering and flow characteristics. Proper sizing prevents blockages and supports consistent hydraulic behaviour..
We evaluate permeability to balance retention time and drainage. This is critical for achieving effective wastewater treatment.
We ensure materials fall within optimal pH ranges and do not introduce harmful chemical reactions that could impact treatment processes.
Low organic content is essential to minimise clogging risk and maintain long-term system performance.
We assess nitrogen, phosphorus, and potassium levels to support plant establishment without compromising treatment gradients.
We test for heavy metals, hydrocarbons, and other pollutants to ensure safe and compliant operation.
