Clean, safe drinking water is essential in every workplace—not just for hydration, but also for employee health, productivity, and compliance. That’s why the Department of Health (DOH) requires that water for public and private use meets the Philippine National Standards for Drinking Water (PNSDW).
For companies, this means scheduling annual water testing through DOH-accredited laboratories. But what exactly happens in these tests, and why does it matter?
What Annual Water Testing Covers
When you send water samples for analysis, laboratories typically check three groups of standards:
1. Bacteriological Tests (Safety First)
- Total Coliform
- Fecal Coliform / E. coli
👉 If coliform bacteria are detected, the water fails automatically. This ensures no contamination from human or animal waste enters your supply.
2. Physical Tests (Look, Smell, Taste)
- Color & Odor
- Turbidity (clarity)
- Taste
- pH (6.5–8.5)
- Total Dissolved Solids (TDS ≤ 500 mg/L)
👉 These determine if the water is not just safe, but also pleasant to drink—crystal clear, odor-free, and great-tasting.
3. Chemical Tests (Long-Term Health)
- Chloride (≤250 mg/L)
- Sulfate (≤250 mg/L)
- Nitrate (≤50 mg/L)
- Iron (≤1.0 mg/L)
- Manganese (≤0.4 mg/L)
- Fluoride (≤1.5 mg/L)
- Hardness (≤300 mg/L)
👉 These parameters ensure water won’t cause health problems when consumed daily over months or years.
Why It Matters for Offices
Many companies assume water from refilling stations or delivered jugs always passes these standards. But in reality:
- Jugs are reused up to 30–50 times, making scratches and dents that harbor bacteria.
- Poor handling during refilling and delivery can reintroduce contamination.
- Inconsistent monitoring means some offices are unknowingly serving water that would fail DOH testing.
