The Importance of Professional Water Testing

While municipal water supplies in London are generally safe, a variety of factors can still impact the quality and safety of the water coming out of your taps:
– Contaminants can enter the water through breaks or leaks in pipes, especially in older buildings
– Plumbing materials like lead, copper, or iron can leach into water as pipes corrode over time
– Water that stagnates in pipes can foster bacteria growth
– Groundwater may become contaminated from industrial runoff, pesticides, or sewage
– Some emerging contaminants are not yet regulated or routinely tested for by public utilities
Any of these issues can potentially expose you to hazardous chemicals, heavy metals, microbes, or other pollutants that pose health risks. And some contaminants, while not necessarily dangerous, can still cause unpleasant odors, tastes, or staining. That’s why it’s so important to have your water professionally tested, especially if:
– You have an older home or building with original plumbing
– You notice any change in the color, cloudiness, taste, or smell of your water
– You experience frequent plumbing leaks, clogs, or other issues
– There is construction or excavation work occurring near your property
– You use well water or another private water supply
As your local water quality expert, I provide the advanced testing and knowledgeable analysis you need to identify any problems and keep your water clean, clear, and contaminant-free. I am certified by the United Kingdom Accreditation Services (UKAS) to ISO/IEC 17025:2017 standards for the competence of testing laboratories. With my help, you can have complete confidence in the safety and quality of your home or business’s water.
Comprehensive Testing for Contaminants and Quality


Using cutting-edge equipment and methods, I am able to accurately test water for a complete range of potential contaminants and quality issues:
Microbiological – I test for the presence of bacteria, viruses, and other microorganisms that can cause serious gastrointestinal illness and infections. This includes coliforms, E. coli, hepatitis A, giardia, cryptosporidium, and more.
Chemical – From industrial pollutants to pesticides to disinfection byproducts, I analyze water samples for over 100 different chemical contaminants, many of which are toxic and carcinogenic. I test for benzene, chloroform, trichloroethylene, PCBs, chlorine, nitrates/nitrites, and numerous others.
Heavy Metals – Even at low levels, heavy metals like lead, mercury, arsenic, and cadmium can be hazardous to your health if consumed over time. I use atomic absorption spectroscopy and other advanced techniques to detect even trace amounts of these dangerous metals.
Radiological – While not common, radiological contaminants like uranium, thorium, and plutonium can sometimes occur in water. I use radiochemistry analysis to test for radioactive isotopes and ensure the radiological safety of your water.
Hardness and Mineral Content – I measure the levels of calcium, magnesium, iron, manganese and other minerals in your water. Imbalanced or excessive mineral content can cause problems like pipe corrosion, limescale buildup, staining, or unpleasant odors and tastes.
pH and Corrosivity – Water that is too acidic or alkaline can corrode pipes and fixtures, leaching metals and contaminants into the water supply. I conduct pH testing to assess the acid-base balance and corrosivity of your water.
Turbidity and Particulates – Turbidity is the measure of suspended particles in water that can make it cloudy or murky. High turbidity can indicate contamination issues and also interfere with disinfection treatments. I test for turbidity and analyze the composition of any particulate matter.
Regardless of where your water comes from, how old your building is, or what problems you suspect, I will conduct a thorough battery of tests to precisely analyze the contents and quality of your water. I strictly follow all official standard methods, including those from the UK Environment Agency’s Monitoring Certification Scheme (MCERTS) and The Microbiology of Drinking Water (2002). My state-of-the-art laboratory equipment includes:
– Inductively coupled plasma mass spectrometry (ICP-MS) and optical emission spectrometry (ICP-OES) for heavy metal analysis
– Gas chromatography-mass spectrometry (GC-MS) for volatile organic compound (VOC) detection
– High performance liquid chromatography (HPLC) for chemical analysis
– UV-VIS spectrophotometry for nitrates, phosphates, chlorine and more
– Membrane filtration and enzyme substrate methods for microbiological testing
– Turbidimeters and laser diffraction particle size analyzers for turbidity and particulates
With these powerful analytical tools and my extensive water chemistry expertise, no well or tap water contaminant will go undetected. You can trust my testing to deliver the most accurate and reliable results regarding the safety and quality of your water.
Detailed Reports and Recommendations

My water analysis services go beyond just testing. I provide every client with an extensive printed report detailing the findings and results of the water quality tests conducted on their property. Your personalized report will include:
– Testing methods, equipment, and any relevant analytical methods used
– Complete rundown of specific contaminants and parameters tested
– Quantified measurements of any contaminants detected
– Comparison of contaminant levels to UK and EU water quality standards and health guidelines
– Overall assessment of water quality and any areas of concern
– Specific recommendations for any water treatment, plumbing repairs, or other remedial actions needed
I review the results in depth to determine if the levels of any contaminants found exceed the allowable limits set by the UK and EU, including the European Drinking Water Directive and the UK Water Supply (Water Quality) Regulations. I base my water quality standards and health risk assessments on official guidelines from the UK Drinking Water Inspectorate (DWI), WHO, and other scientific authorities.
More importantly, I don’t just hand you lab results and leave you to decipher their meaning. I fully explain what the measurements indicate about the condition of your pipes and water supply. And if any issues are found, I provide customized step-by-step recommendations for how to treat and resolve them.
Whether you need a whole-house filtration system, a reverse osmosis setup, faucet filters, pipe repairs, or anything else, I will recommend the most effective solutions to restore the safety and quality of your water. I can advise you on the best treatment systems and hook you up with qualified plumbers and installers to implement them properly.
With my detailed reports and knowledgeable guidance, you will have all the information and expert advice you need to protect your water and the health of your family or customers. I make it simple to understand the state of your water and take any needed corrective actions to get it back up to standard.

Health Effects of Common Water Contaminants



Lead
Lead is a toxic heavy metal that can leach into water from old lead pipes, solder, and brass fittings. Even low levels of lead exposure can cause serious health effects, especially in children and pregnant women. Lead harms the nervous system, causing developmental delays, learning difficulties, irritability, fatigue, and behavioral problems in kids. In adults, it can cause high blood pressure, decreased kidney function, and reproductive issues.
Bacteria (E. coli, Total Coliforms)
Bacteria like E. coli and other coliforms are microbiological contaminants that come from sewage, animal waste, or decaying organic matter entering the water supply. Consuming water with these bacteria can cause acute gastrointestinal illness, with symptoms like diarrhea, vomiting, cramps, nausea, headaches, and fever. Infants, the elderly, and immunocompromised people are at higher risk for severe symptoms and complications.
Nitrates/Nitrites
Nitrates and nitrites are inorganic compounds that can contaminate water from fertilizer runoff, septic tanks, or sewage. The main health concern with nitrates is infant methemoglobinemia or “blue baby syndrome.” Nitrates reduce the blood’s ability to carry oxygen, which can be fatal for infants. Some studies also link nitrates to increased risk of cancers, thyroid issues, and reproductive problems.
Arsenic
Arsenic is a highly toxic metalloid that can contaminate groundwater from natural rock formations or industrial pollution. Long-term exposure to arsenic, even at low levels, significantly increases the risk of various cancers, including skin, lung, bladder, and kidney cancers. Non-cancer effects include skin lesions, cardiovascular disease, diabetes, cognitive deficits, and harm to fetal development during pregnancy.
Chlorine Byproducts (THMs, HAAs)
Disinfection of water with chlorine can produce harmful byproducts like trihalomethanes (THMs) and haloacetic acids (HAAs) if organic matter in the water isn’t properly filtered out first. Studies link these chemicals to increased risk of bladder, colon, and rectal cancers. They may also be associated with reproductive problems like miscarriage, birth defects, and infertility. Other health effects can include liver, kidney and central nervous system issues.
Pesticides and Herbicides
Chemical pesticides and herbicides used in agriculture and landscaping can infiltrate water sources and pose health risks if consumed, even at trace levels. Different products have various toxic effects, but general health concerns include increased cancer risk, reproductive and endocrine disruption, liver and kidney damage, and neurological effects. Exposure during pregnancy is particularly concerning for fetal development.
These are just some of the more common waterborne contaminants and their potential health consequences. The reality is that there are numerous chemical, biological, and radiological pollutants that can contaminate water and harm human health in both acute and chronic ways. The best way to protect yourself is to have your water regularly tested so you can catch any problems and take steps to treat and decontaminate your water if needed. I’m here to provide the comprehensive testing and expert guidance you need to keep your water safe.
