Whether it is domestic water, well water, or wastewater, all can pose potential risks of contamination if quality control is not conducted periodically. Water testing is not only a legal requirement in many cases, but also a crucial measure to protect the health of families, businesses, and the public.
So where can you get water testing done reliably? How much does it cost? What is the process? VNTEST will help you understand clearly and choose the right testing agency through the article below.
Why is periodic water testing necessary?
Water testing helps detect non-compliant indicators early, allowing for timely treatment solutions to avoid long-term risks.
Risks of not testing water
- Microbial contamination: E. coli and Coliform cause intestinal diseases
- Heavy metals: Arsenic, lead, and mercury cause chronic poisoning
- Chemical and pesticide residues
- Severe health impacts on children and the elderly
Cases where water testing is mandatory
- Well water used for daily household activities
- Bottled drinking water, RO water, and purified water
- Water used in food, cosmetics, and medical production
- Environmental dossiers and business permit applications
- Periodic inspections required by regulatory authorities
