Request Water Testing QuoteWhat is Packaged Drinking Water Testing?
Definition: Packaged drinking water testing is a comprehensive laboratory procedure that evaluates water sourced from any potable supply, including municipal sources, borewells, or surface water, after it has undergone treatment processes such as filtration, reverse osmosis, and disinfection, to confirm it is safe, hygienic, and fit for direct human consumption.
Difference Between Packaged Drinking Water and Packaged Natural Mineral Water
- Packaged Drinking Water (IS 14543): Can be sourced from any potable water supply, including municipal water. It is subjected to extensive treatment such as Reverse Osmosis (RO), UV sterilization, ozonation, and artificial remineralization to guarantee safety.
- Packaged Natural Mineral Water (IS 13428): Must be sourced directly from a natural or drilled underground reservoir and retains its inherent mineral composition. Extensive treatments that alter the original mineral profile are strictly prohibited.
Importance of Testing Packaged Drinking Water
Because packaged drinking water is consumed daily by millions across households, offices, hospitals, and public spaces, its safety cannot be left to assumption. Laboratory testing provides essential quality assurance by confirming that all treatment processes have effectively removed pathogens, chemical contaminants, and impurities, while ensuring the final product meets every parameter required for safe, legal sale under regulatory compliance.

What is IS 14543?
Overview of IS 14543: IS 14543 is the official Indian Standard established by the Bureau of Indian Standards (BIS) that specifically governs the requirements for "Packaged Drinking Water (Other than Packaged Natural Mineral Water)."
Purpose of the Standard: The primary purpose is to ensure that water sourced from any supply, whether municipal, borewell, or surface source, is treated, purified, and bottled in a manner that guarantees complete safety for human consumption. The standard permits extensive treatment processes including reverse osmosis, ultra-filtration, UV disinfection, ozonation, and remineralization.
Scope & BIS Certification Requirements: The scope covers all packaged drinking water offered for human consumption, excluding natural mineral water. To achieve BIS certification, manufacturers must establish robust in-house quality control and submit regular samples to a recognized packaged drinking water testing lab. The water must pass all mandatory quality parameters, including physical, chemical, microbiological, and toxicological limits.
Difference Between IS 14543 and IS 13428: While IS 14543 allows for the creation of safe drinking water from any source via heavy processing, IS 13428 strictly protects the "natural" status of mineral water sourced from protected underground reservoirs. For manufacturers, an IS 14543 license is the standard route for bottled water brands sold at scale across general retail and hospitality channels.
Water Quality Parameters We Test
Our comprehensive IS 14543 testing protocols cover all mandatory parameters. Below is a detailed matrix of our analytical capabilities:
| Parameter | Purpose | Typical Requirement (IS 14543) | Importance |
|---|---|---|---|
| Physical Parameters | |||
| Appearance / Colour | Assess visual purity. | Clear, Max 1 Hazen Unit | Ensures aesthetic acceptability; even minor colour indicates inadequate filtration. |
| Odour & Taste | Sensory evaluation. | Unobjectionable | Off-tastes or odours indicate residual chemicals or biological activity. |
| Turbidity | Measures water clarity. | Max 1 NTU | High turbidity indicates insufficient filtration and can shield microbes from disinfection. |
| Chemical Parameters | |||
| pH | Determines acidity/alkalinity. | 6.5 to 8.5 | Ensures palatability and system compatibility; extreme pH affects taste and safety. |
| Total Dissolved Solids (TDS) | Total mineral and salt content. | Max 500 mg/L | Must be controlled through treatment to give a consistent, neutral taste profile. |
| Total Hardness | Measures calcium and magnesium salts. | Max 200 mg/L | Excess hardness affects taste and indicates incomplete softening or RO performance. |
| Chlorides & Sulphates | Measures dissolved salts. | Cl: Max 200 mg/L, SO4: Max 200 mg/L | Elevated levels can impart a salty or bitter taste and indicate treatment inefficiency. |
| Fluoride | Detects fluoride content. | Max 1.0 mg/L | Strictly regulated; excess levels are linked to dental and skeletal fluorosis. |
| Residual Free Chlorine | Confirms disinfection status. | As specified, tightly controlled | Must be within safe limits to confirm disinfection without affecting taste. |
| Nitrate & Nitrite | Indicators of source contamination. | Nitrate: Max 45 mg/L, Nitrite: Max 0.02 mg/L | High levels indicate that source water may be contaminated by agricultural runoff or sewage. |
| Toxic Substances & Heavy Metals | |||
| Lead & Arsenic | Toxic elemental contaminants. | Highly restricted (e.g., Arsenic Max 0.01 mg/L) | Must be virtually undetectable; even trace exposure poses serious health risks. |
| Cadmium & Mercury | Bioaccumulative toxins. | Strictly limited | Must be absent to prevent long-term toxic accumulation in consumers. |
| Pesticide Residues | Detects agrochemical contamination. | Individual and total residue limits apply | Critical for sources near agricultural land; must comply with FSSAI thresholds. |
*Note: Because packaged drinking water can originate from varied sources, treatment validation and consistent batch testing are essential to guarantee IS 14543 compliance.
Microbiological Parameters
Since packaged drinking water is treated through disinfection systems, verifying the elimination of all pathogens is the most critical testing component. Testing includes:
