Start with the records’ purpose

Pollution archives can show how a city’s industrial growth, wastewater systems and regulatory decisions intersected. A parliamentary answer on Budha Nullah discusses monitoring by central and state pollution control authorities. The description tells us what the report’s authors observed or recorded, but it does not identify the contribution of each factory. Ask when a document was created, which organisation produced it and what question it was meant to answer. A planning study, a factory inspection and a resident’s testimony each see different parts of the problem; reading one alone can give an incomplete picture.[1]

Compare measurements carefully

A research study of Budha Nullah sampled water at sites from upstream to downstream through Ludhiana. Such measurements can help compare places and identify changes along a watercourse, provided the sampling dates and methods are recorded. Different pollutants and seasons may produce different results, and a laboratory result at one location cannot establish exposure for every resident. When comparing reports, check whether they use the same sampling point, units and standard, and distinguish a non-compliant measurement from a general claim about an entire river. Recording the source and date lets later readers revisit the comparison as further evidence becomes available.[2]

Follow decisions as well as water

An audit by India’s Comptroller and Auditor General reported shortcomings in treatment and pollution-control arrangements connected with Budha Nullah. Audit findings can be compared with project budgets, inspection reports, tribunal submissions and later water-quality data to see whether identified problems were addressed. Be precise about dates: an old audit is evidence of its period, not proof that a particular facility remains unchanged today. Local interviews can add information about livelihoods and the effects people perceived. Together these sources can connect industrial activity to infrastructure and public decisions without attributing all pollution to a single cause.[3]
