It started, as a lot of pollution stories now do, with a phone video. Someone posted footage of black, foul-smelling water flowing near Parawada JN Pharma City on Instagram last Friday, and within days the Andhra Pradesh Pollution Control Board (APPCB) had served show-cause notices to 95 industries operating in the area, one of the state's largest pharmaceutical manufacturing clusters.
From a Social Media Post to a State-Wide Enforcement Sweep
The chain of events here is worth laying out because it says something about how environmental enforcement actually gets triggered in practice. A video showing discoloured water in drains and stormwater channels near Pharma City went up on Instagram, caught the attention of Andhra Pradesh Deputy Chief Minister Pawan Kalyan, and he directed APPCB officials to inspect the area. That inspection, which involved collecting water samples and asking units to submit reports, escalated quickly into formal show-cause notices across nearly 100 industries.
APPCB has now sought written explanations from all 95 units regarding the suspected discharge and the reported foul odour, and has directed every one of them to undertake corrective measures. Crucially, the pollution control board has also told these industries to strictly comply with the conditions attached to their Consent to Operate (CTO) and hazardous-waste authorisations, which are the core legal documents governing what a pharma unit is actually allowed to discharge and how.
What Hasn't Been Established Yet
Here's the part that matters for anyone following this story closely: the exact source of the black water has not been pinned down. APPCB's notices are part of an ongoing investigation, not a finding of guilt against any specific unit. Officials have submitted a detailed report covering the inspections, the notices and the corrective measures required to the Deputy Chief Minister's office, and the units have been directed to prevent untreated discharge, strengthen waste handling, install monitoring systems and comply with environmental norms going forward, regardless of which specific facility turns out to be responsible for the contamination that was filmed.
Why Pharma City Clusters Are a Recurring Flashpoint
Parawada and the broader Anakapalli pharmaceutical belt aren't new to scrutiny. Pharmaceutical manufacturing generates wastewater that's genuinely harder to treat than typical municipal sewage, loaded with active pharmaceutical ingredients, solvents and process chemicals that standard biological treatment struggles to fully break down. When dozens of such units operate in close proximity, as they do in a dedicated pharma city, tracing a specific pollution event back to its source becomes a real forensic challenge, even for a well-resourced regulator, which is partly why this investigation has started with notices to all 95 units rather than a single targeted action.
This is a pattern that's shown up elsewhere in India's pharma manufacturing belts too, from Himachal Pradesh's Baddi cluster to similar industrial zones, where effluent from multiple units ends up sharing common drains and a Central Effluent Treatment Plant (CETP) that isn't always equipped to handle every unit's actual discharge load. Properly functioning effluent treatment infrastructure at the individual unit level, not just at a shared CETP, is generally what prevents this kind of cluster-wide blame game in the first place.
Key Highlights

- Deputy CM Pawan Kalyan directed the inspection after the video showing black, foul-smelling water was posted on Instagram.
- The exact source of the pollution has not yet been established; the notices are part of an ongoing investigation.
- Units have been directed to comply strictly with their Consent to Operate and hazardous-waste authorisation conditions.
- APPCB has asked all 95 units to prevent untreated discharge, strengthen waste handling and install monitoring systems.
