Water analysis

We are committed to providing accurate, reliable and rapid services from our purpose built laboratories in London.

Some of our work concerns complaints about taste, discolouration or smell of drinking water. These problems generally stem from the deterioration of the internal plumbing system, due to poor maintenance or faulty design. Inadequate storage conditions, warming, stagnation and incorrect use of building materials which provide an ideal environment for microorganisms to breed, such as legionella and pseudomonas.

• We offer a fast, affordable service to examine and identify bacteria, algae, fungi, yeasts, and moulds present. These tests range from simple bacteria colony count, coliform and E.coli and pseudomonas analysis to more specialist techniques for the isolation of organisms such a legionella bacteria.
• Analysis can assist in providing a clear picture of the quality, maintenance and operation of water treatment and air conditioning systems.
• Our tests allow us to evaluate the efficiency of specific biocides and disinfectants, so that we can advise you on dosage, and the effectiveness of water systems and hygiene practises in place.
• We test samples for physicochemical components, enabling us to ensure relevant standards are met, the condition of systems including rates of corrosion is monitored and causes of blockages are determined.
• We can assess water quality on an ongoing basis so that you are confident the swimming pool, spa or interactive water feature treatment regime is operating properly and avoiding any risk to employees or customers as indicated by HSG 282, the Health and Safety at Work Act and COSHH.
• Should any air or water quality problems arise – through, say, failing treatment plant, corrosion or microbiological contaminants – we can investigate the cause and advise on the most appropriate solution.
• We conduct regular swimming pool operator and swimming pool supervisor training or refresher programmes. These can be City&Guilds accredited or tailored to match your individual needs and the specific treatment regimes you have in place.
• We safely carry out Cryptosporidium investigations to ensure your facility is safe when a local outbreak occurs.
