When industrial units or commercial facilities face water issues such as contaminated worker coolers, rejected export shipments, or notices from environmental protection agencies, an independent laboratory test provides clear evidence of the water quality.
Working with an accredited lab gives factories verified test data that auditors, environmental inspectors, and international buyers accept without raising doubts. Manufacturers and plant operators use these testing services to:
A fully equipped testing facility runs four practical benches: a physical and chemical testing section, an instrumental metals analysis lab, a sterile microbiology room, and a sample log desk that secures chain of custody. SAB Labs runs permanent laboratories in Karachi and Lahore, handling water analysis requirements for manufacturing facilities across Sindh, Punjab, and broader Pakistan.
Industrial plants and commercial properties need clear lab numbers to avoid EPA challans, protect expensive utility machinery, and keep factory workers safe from waterborne sickness. SAB Labs tests water across Pakistan according to the specific framework your facility has to answer to.
Potable water testing tells you straight away whether water is safe to drink or contaminated. SAB Labs screens drinking water against National Environmental Quality Standards (NEQS), Punjab Environmental Quality Standards (PEQS), and World Health Organisation (WHO) benchmarks. We routinely test municipal lines, private tube-well bores, commercial dispenser supplies, factory coolers, and residential colony tanks.
Routine testing covers the basic physical and chemical parameters that show taste, mineral, or salt problems:
For toxic mineral risks, we use atomic absorption spectrometry to detect trace metals. This screens for arsenic, lead, iron, cadmium, chromium, and copper down to parts-per-billion levels. If your bore has high arsenic or old distribution pipes are leaching lead, our test reports state the exact readings next to the legal limits.
Every manufacturing facility that releases wastewater into public sewers, open land, or coastal waters must comply with provincial pollution control laws. SAB Labs provides industrial wastewater characterization lab services, testing factory discharge against:
Discharging wastewater that exceeds legal limits leads to heavy fines, litigation, or factory sealing orders from Sindh EPA or Punjab EPA. Our wastewater panel tests for the exact discharge parameters regulators look for during unannounced factory visits:
Every lab report lays out your raw or treated discharge numbers alongside the provincial limits, giving you the documentation you need for quarterly EPA filings.
Textile processing mills and export denim laundries face strict chemical guidelines from retail brands like Nike, H&M, Inditex, and PVH. SAB Labs tests factory wastewater and process lines against Zero Discharge of Hazardous Chemicals (ZDHC) Wastewater Guidelines and Zero Liquid Discharge (ZLD) plant operational targets.
Our lab checks wastewater against the ZDHC MRSL (Manufacturing Restricted Substances List) across conventional parameters, heavy metals, and priority hazardous organics. For mills operating ZLD systems, we test RO feed, permeate, and reject streams. These tests verify recovery rates, measure silica build-up, and confirm that recycled water won’t alter shade consistency or ruin dyeing batches when reused on the production floor.
In food, dairy, and beverage plants, water touches everything from raw ingredient washing to batch mixing and CIP (clean-in-place) plant sanitation. Poor incoming water ruins taste, fizzes carbonation off-balance, or triggers immediate food authority crackdowns.
SAB Labs analyzes process water against food-grade standards and regional food authority requirements. We screen for taste-altering organics, mineral hardness, total alkalinity, and trace iron that can oxidize and discolor finished products. We also benchmark reverse osmosis units, checking whether membranes are stripping out excess salts or leaking minerals into mixing tanks.
Using bad groundwater for irrigation ruins soil fertility, locks up fertilizers, and kills crop yields over time. SAB Labs runs agricultural water testing for commercial farms, seed companies, and corporate agribusinesses across the agricultural belts of Sindh and Punjab.
We focus on four key agricultural metrics:
These lab values give farm managers the exact numbers needed to adjust gypsum applications, change leaching schedules, or alter fertilizer formulas.
Bacterial contamination spreads fast through drinking lines, storage sumps, and worker water coolers, causing sudden absenteeism on production floors. Our microbiology team screens water samples using standard membrane filtration and multiple tube fermentation techniques.
A standard bacterial water testing service tests for:
Our testing verifies whether your chlorination pumps, UV lamps, or ozone systems are actually killing bugs or running idle.
Overseas export buyers do not accept goods or factory discharges containing banned industrial chemistry. When European and US brands audit suppliers, they require targeted tests run on advanced gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS) instruments.
Certain azo dyes break down into banned aromatic amines that cause cancer, which is why EU REACH regulations strictly ban them from export apparel and leather goods.
SAB Labs screens process wash water, raw dye mixes, and effluent for the 24 restricted aromatic amines listed under REACH Regulation (EC) No 1907/2006. Our bench team uses GC-MS to catch trace residues down to parts-per-million and parts-per-billion levels. These tests provide exporters with third-party proof that their dye baths and wash discharges meet international textile regulations.
Alkylphenol ethoxylates (APEOs), particularly nonylphenol ethoxylates (NPEOs) and octylphenol ethoxylates (OPEOs), were standard ingredients in cheap scouring detergents, wetting agents, and spinning lubricants. These chemicals break down into toxic alkylphenols that disrupt hormones and pass straight through regular biological wastewater plants without degrading.
SAB Labs runs liquid chromatography-tandem mass spectrometry (LC-MS/MS) to detect:
Running routine tests on wash baths and wastewater confirms your chemical store is not inadvertently using raw materials with banned NPEO surfactants.
International brand supply chain protocols require broad chemical clearance beyond basic dyes and detergents. SAB Labs screens discharge water and raw chemical inputs for trace industrial contaminants:
Testing these parameters early isolates chemical issues on the factory floor before an export shipment is flagged at European customs.
A lab test report is only as credible as the analytical methods and bench standards behind it. SAB Labs follows standardized wet-chemistry and instrumental protocols backed by third-party accreditation.
SAB Labs tests water according to the Standard Methods for the Examination of Water and Wastewater, published jointly by the American Public Health Association (APHA), the American Water Works Association (AWWA), and the Water Environment Federation (WEF).
Our primary testing references include:
Accreditation proves that a laboratory’s instruments are calibrated, its test methods are validated, and its staff knows how to run the chemistry. SAB Labs operates permanent facilities under ISO/IEC 17025 accreditation under reference LAB-185.
This accreditation means:
A test result is only as accurate as the sample pulled from the pipe. If a sample sits in a warm truck or an unwashed bottle for two days, the chemical and bacterial readings will not reflect the actual water source.
SAB Labs maintains field sampling technicians across Karachi who handle direct sample collection from factory premises in SITE Area, Korangi Industrial Area, Landhi, North Karachi, Federal B Area, and Port Qasim. Our technicians carry calibrated field meters to record on-the-spot pH, temperature, and dissolved oxygen before filling sample bottles.
For factories and projects in Punjab, KPK, Balochistan, and interior Sindh, we accept samples via overnight courier dispatch:
To keep your water sample stable from the drain to the testing bench, follow these handling rules:
A test report must give your factory legal, verifiable proof that satisfies regulators, auditors, and technical directors. SAB Labs issues tamper-evident, audit-ready certificates for every test run.
SAB Labs test certificates present data clearly without vague summaries:
Plant managers can immediately see which parameters passed, which failed, and the exact margin of compliance.
When our field technicians collect samples directly from your plant, your final audit file includes photographic proof of the outfall, sampling valve, and on-site meter readings taken during collection.
Every official report includes:
Water testing costs in Pakistan range from PKR 5,000 for basic drinking tests to PKR 45,000 or more for comprehensive industrial wastewater panels. Total testing cost depends on the specific parameter list and the instruments required:
Standard water testing takes between 3 and 7 working days from sample intake to final report issuance. Turnaround depends on the test methods required:
Express testing options are available when you need urgent results for customs clearance or time-sensitive buyer audits.
SAB Labs tests water against Pakistani environmental laws, provincial rules, and international brand standards. We regularly test against:
Yes, water samples can be submitted from any industrial zone or city across Pakistan. While SAB Labs provides dedicated on-site sampling teams in Karachi and Lahore for direct factory pickups, clients in Faisalabad, Sialkot, Gujranwala, Rawalpindi, Multan, Hub, and Hattar routinely send samples via overnight courier. Our technical team guides you on sample preservation, bottle selection, and ice packing before you dispatch to ensure the samples arrive in test-ready condition.
Yes, SAB Labs tests industrial effluent against ZDHC Gateway requirements and Zero Liquid Discharge (ZLD) plant performance criteria. We test wet-processing discharge for all ZDHC MRSL chemical categories, including APEOs, banned azo dyes, phthalates, chlorobenzenes, and heavy metals. For mills running ZLD setups, we test RO feed, permeate, and concentrated reject streams to measure recovery efficiency, COD reduction, and salt separation.
Water samples must be preserved by keeping them cold at 4°C in appropriate bottles and adding specific chemical preservatives where required. Follow these four basic rules:
