Water Quality Sampling
Scientific analysis and microbiological testing to ensure your water supply is chemically balanced, contaminant-free, and safe for human consumption.
Service Overview
At Greensurv, we provide expert Water Quality Sampling services that go beyond simple visual checks. While a Legionella assessment identifies structural risks, physical water sampling provides the empirical evidence needed to confirm that your water is chemically safe and free from harmful pathogens. Whether you are managing a commercial office, a healthcare facility, or a private residential supply, regular sampling is the only way to detect "invisible" threats like E. coli, Lead, or chemical imbalances. Our team uses sterile collection techniques and partners with UKAS-accredited laboratories to provide highly accurate results. By choosing Greensurv, you are ensuring that your water meets the stringent requirements of the Private Water Supplies Regulations and the Water Supply (Water Quality) Regulations, protecting the health of everyone who drinks or uses water on your premises.
Microbiological & Pathogen Analysis
This phase focuses on identifying harmful bacteria that can cause immediate illness. We use specialized, sterile equipment to capture samples from across your system—from the point of entry to the furthest tap—to ensure no contamination is occurring within your internal pipework.
Verifying if water is "wholesome" and safe for drinking, cooking, and hygiene.
Testing for indicators of fecal contamination or system breaches.
Measuring the general level of bacteria in the system to assess overall cleanliness and stagnation.
Critical for healthcare and high-risk environments where water comes into contact with vulnerable individuals.
Targeted testing for Legionella pneumophila when systems fail to maintain thermal control.
Chemical, Mineral, and Heavy Metal Testing
Water chemistry can affect not only human health but also the longevity of your plumbing infrastructure. We analyze the mineral content and presence of heavy metals that can leach from old pipes or enter through the main supply.
Testing for Lead, Copper, and Nickel, which are common in older UK building infrastructures.
Monitoring acidity and calcium levels to prevent pipe corrosion or excessive scale buildup.
Ensuring that secondary disinfection levels are adequate to kill bacteria but safe for consumption.
Essential for agricultural or private borehole supplies to identify agricultural runoff.
Detecting traces of pesticides, solvents, or hydrocarbons in high-risk industrial zones.
Key Benefits
Absolute Health Assurance
Provide definitive proof that your water is free from dangerous pathogens and toxins.
Early System Diagnosis
Identify "hidden" issues like corroding pipes or failing filtration units before they become a health crisis.
Regulatory Compliance
Fulfill your "Duty of Care" and meet the specific requirements for landlords, employers, and care providers.
Certified Results
All samples are processed in UKAS-accredited labs, providing you with a legally defensible audit trail.
Our Process
STEP 01
Sampling Strategy
We identify the most representative sampling points across your site at Greensurv, focusing on high-use areas and potential "dead legs."
STEP 02
Aseptic Collection
Our technicians use specialized neutralizers and sterile containers to collect samples without introducing any external contamination.
STEP 03
Laboratory Analysis
Samples are transported in temperature-controlled environments to a UKAS lab for detailed microscopic and chemical analysis.
STEP 04
Technical Interpretation
You receive a clear "Pass/Fail" report. If a sample fails, our experts provide immediate advice on disinfection or system repairs.
Frequently Asked Questions
How often should water be sampled?
For most commercial buildings, an annual potability test is recommended. However, healthcare sites or those with private supplies may require quarterly or even monthly checks.
Is the water safe to drink while you are taking samples?
Yes, our sampling process is non-intrusive. We only require a small amount of water from your taps, and it does not affect the rest of the supply.
What happens if my water sample fails?
If a sample fails, we immediately notify the "Responsible Person." We typically recommend a system flush, chlorination (disinfection), and a follow-up re-test.
Why should I test for Lead?
If your building was built before 1970, there is a high chance of lead pipework. Lead is a cumulative toxin, so testing is vital for the safety of children and long-term occupants.
How long does it take to get the results?
Microbiological results typically take 3–5 working days, while complex chemical analysis can take up to 10 days. We provide a preliminary report as soon as the lab finishes.
