Why Test Your Water?
Water touches every part of life and business, from what we drink and where we swim, to the medicines we manufacture and the environment we protect.
However, water quality can easily be compromised by:
- Heavy metals, pesticides, and industrial pollutants
- Microbial contamination (E. coli, coliforms, pathogens)
- Excessive mineral content affecting health and equipment performance
- Chemical residues and toxins harmful to people and ecosystems
Regular Water Testing Helps You Ensure:
Regular Water Testing Helps You Ensure:
- Protection of public health and safety
- Compliance with FSSAI, BIS, WHO, CPCB, and ISO standards
- Prevention of penalties, shutdowns, and operational risks
- Stronger trust with customers, regulators, and stakeholders
Types of Water We Test
Drinking Water

FAQs
How common are waterborne diseases in India?
A study estimates that around 37.7 million Indians are affected by waterborne diseases like diarrhoeal every year.
Is Bangalore’s drinking water unsafe?
Recent studies show that between ~30% and ~70% of tested water sources or household samples in different parts of Bengaluru exceed one or more safe-water standards (for microbiological or chemical parameters), depending on the zone and the parameter tested.
What makes Prewel Labs a reliable water testing partner?
Our facility in Bangalore is NABL accredited and follows rigorous standards described in ISO 17025:2017 along with those enforced by BIS and APHA. We are an ISO certified lab in the heart of Bangalore.
What standards does Prewel Labs follow for water testing?
We follow IS 10500 for drinking and borewell water, IS 14543 for packaged drinking water, IS 13428 for natural mineral water, IS 4251 for food processing water, and CPCB guidelines for STP testing.
Can contaminated water cause skin infections?
Yes. Testing helps protect you from skin infections caused by chemical or microbial contaminants.
Can water quality impact hair fall?
Yes. Avoid hair fall by ensuring your water is free from hardness, microbes, and harmful chemicals.
How does poor water quality damage home appliances?
Hard water causes scaling and buildup that can damage appliances such as geysers, washing machines, and RO systems.
Why should businesses test water used in food processing?
Water plays a direct role in food safety. IS 4251 ensures water used in food processing is safe and compliant.
How often should water be tested?
For drinking: every 3 months is recommended.
For industries: monthly, quarterly, or based on regulatory guidelines (IS 10500, WHO, FSSAI, pharma GMP, etc.).
For RO plants: monthly or after any maintenance.
What types of water can be tested?
Drinking water, borewell water, RO water, packaged drinking water, industrial water, cooling tower water, boiler feed water, Construction water, Dialysis water, process water, purified water (PW), WFI, and wastewater.
What testing parameter are included in water testing at Prewel Labs?

Usually 500 ml to 5 litres, depending on test parameters.
How long can a sample be stored before testing?
Ideally within 6 hours for microbiology.
Chemical testing can be done within 24 hours, depending on the parameter.
How long does it take to get results?
3-5 days depending on the complexity of tests.
Microbiology tests may require 24–48 hours for incubation.
Will I receive a soft copy of the report?
Yes. We will send PDF reports via email or dashboard access.
Do you provide NABL-accredited reports?
Yes, we provide NABL accredited reports for the specific parameters.
Is my water safe after testing?
Report interpretation will tell you. If levels exceed limits, we will advise corrective actions (new filters, RO servicing, flushing, chlorination, etc.).
What standards are used for comparison?

Yes. Monthly, quarterly, or custom packages are available.
Why does RO water taste flat?
RO removes minerals, so the water may taste bland. This is normal.
My water has smell/colour. What should I test?
Perform full chemical + microbiological testing to identify the cause (Residual free chlorine, Manganese, iron, sulphur, organic contamination, bacteria, etc.).
