Water Quality Services Ltd - Sampling, monitoring and analysis
Water Quality Services Ltd (WQS) provides a bespoke service sampling, monitoring, and analyzing water for process, environmental, recreational, and domestic applications. Broad areas of the business are as follows:-
Concrete mixing water analysis for BS EN 1008 compliance
Analysis of trade effluent discharged to sewers and controlled waters
Other services, including monitoring ground water, surface water, private water supplies, and swimming pools or spa pools.
Water assimilates materials as suspensions, emulsions, and solutions resulting in a diverse range of determinands that can be tested for. Water has many different applications requiring different methods of analysis for the same determinand. Details are included in the Environment Agency "Technical Guidance Note M18".
Sampling, monitoring, and analysis often have to follow specific requirements. Some samples have to be tested quickly, or have a sample preservative added. Test methods have to be fit for purpose, giving sufficient precision and accuracy over the relevant range of concentrations. Many methods of analysis respond to other materials in the water as well as the determinand being tested for - the matrix effect. Correct documentation and presentation of samples is very important to ensure meaningful test results.
How we work
Quotations are provided describing sampling and test methods to be employed
