Types of Water Testing

A complete guide to water testing categories in India — drinking water, groundwater, packaged water, pharmaceutical water, wastewater, and FSSAI compliance testing. NABL-accredited analysis covering all parameters.

Water Testing — Overview

Water quality testing is a broad field that encompasses many different types of analysis, each serving a specific purpose — from verifying that drinking water is safe for human consumption, to ensuring industrial process water does not corrode equipment, to confirming that pharmaceutical water meets pharmacopoeial purity standards.

Choosing the right type of water test depends on three factors: the source of the water (municipal supply, bore well, river, treated effluent), the intended use (drinking, food processing, industrial, pharmaceutical), and the regulatory requirement (IS 10500, IS 14543, FSSAI, CPCB/SPCB, USP/IP). Auriga Research's NABL-accredited water testing laboratory offers all major water testing categories under one roof.

Frequently Asked Questions

What are the main types of water testing?
Water testing is broadly categorised into: (1) Microbiological testing — detects bacteria, coliforms, E. coli, fungi, and viruses; (2) Physical testing — measures turbidity, colour, taste, odour, and TDS; (3) Chemical testing — determines pH, hardness, alkalinity, chloride, fluoride, nitrate, sulphate, and dissolved minerals; (4) Heavy metals analysis — quantifies lead, arsenic, cadmium, chromium, mercury, and other toxic metals using ICP-MS; and (5) Organic contaminants — pesticides, herbicides, and disinfection byproducts. The appropriate combination depends on the water source and intended use.
What standard is used for drinking water testing in India?
IS 10500:2012 (Indian Standard Specification for Drinking Water) is the primary standard for potable water quality in India. It specifies acceptable and permissible limits for over 40 parameters including physical, chemical, and microbiological quality. IS 3025 (Methods of Sampling and Test for Water and Wastewater) governs the analytical methods. For packaged drinking water, IS 14543 applies. FSSAI regulations govern water used in food processing and manufacture.
What is the difference between drinking water testing and groundwater testing?
Drinking water testing (IS 10500) focuses on potability — whether water is safe and acceptable for human consumption. It includes aesthetics (taste, colour, odour) and health parameters (coliforms, nitrate, fluoride, heavy metals). Groundwater testing covers a broader geochemical profile: major ions (calcium, magnesium, sodium, potassium, bicarbonate, sulphate, chloride), trace elements, pH, TDS, hardness, and potential contamination from agricultural or industrial sources. Groundwater testing also includes parameters relevant to irrigation (SAR — Sodium Adsorption Ratio, RSC — Residual Sodium Carbonate) and bore well suitability.
How often should water be tested?
Testing frequency depends on the source and use: municipal drinking water — at least twice a year (before and after monsoon); bore wells and tanker water — quarterly, more frequently if water quality is variable; food processing water (FSSAI requirement) — annually for licence renewal, and whenever the water source changes; industrial process water — monthly to quarterly depending on the process; pharmaceutical water (purified water, WFI) — daily/weekly in-process monitoring with full USP/IP testing quarterly. New water sources should always be fully tested before use.
What is potability testing of water?
Potability testing determines whether water is safe and acceptable to drink. It covers the full range of IS 10500:2012 parameters — physical (turbidity, colour, TDS), chemical (pH, hardness, alkalinity, chloride, fluoride, nitrate, sulphate, iron, manganese, residual chlorine), heavy metals (lead, arsenic, cadmium, chromium, mercury, selenium), and microbiological (Total Coliform, E. coli, Total Plate Count). A NABL-accredited potability report from Auriga Research is accepted for FSSAI licence applications, bore well commissioning, and regulatory compliance.
What is the difference between physical and chemical water testing?
Physical testing evaluates properties detectable by the human senses or simple instruments: turbidity (cloudiness), colour, odour, taste, total dissolved solids (TDS), and temperature. These parameters give an immediate indication of aesthetic quality. Chemical testing quantifies the dissolved ionic and molecular species in the water: pH, hardness, alkalinity, major anions (chloride, fluoride, nitrate, sulphate, phosphate), major cations (sodium, calcium, magnesium, potassium), and trace elements. Chemical testing determines whether water meets safety thresholds and is suitable for the intended use — drinking, industrial processes, or food manufacturing.
