Kovvur's Air Quality: What the Numbers Tell Us About a Godavari River Town
Tap a highlighted term — or any word — for a quick explanation.
Kovvur is a small but busy municipality sitting on the banks of the Godavari River in East Godavari district, Andhra Pradesh. It is connected to the larger city of Rajahmundry on the opposite bank by three bridges, including the historic Sir Arthur Cotton bridge. Because of its riverside location and road links, Kovvur has grown into a commercial and industrial hub over the decades.
The town hosts some significant industrial players. Andhra Sugars, one of Andhra Pradesh's oldest companies established just before Independence in 1947, has a unit here. So does Avanti Feeds Ltd., a major producer of feed for the aquaculture — that is, fish and prawn farming — industry, with two units in the town. Nearby, the Dowlaiswaram Industrial Estate adds more factories to the mix. All of this industrial activity contributes to the air pollution picture in and around Kovvur.
So what exactly is the air quality like right now? Two trackers give us a snapshot. IQAir, a Swiss-based air quality technology company that collects sensor data from around the world and publishes live dashboards, currently classifies Kovvur's air as 'Unhealthy for Sensitive Groups.' A parallel tracker called aqi.in recorded an Air Quality Index, or AQI, of 85 for Kovvur as of 1 May 2025, which falls in the 'Moderate' category. The Dowlaiswaram Industrial Estate within Kovvur registered a slightly lower AQI of 69, also 'Moderate.'
To understand these numbers, it helps to know how the AQI scale works. AQI is a standardised score that converts pollutant concentration readings into a simple number. A score of 0–50 is 'Good'; 51–100 is 'Moderate', meaning air quality is acceptable but there may be some concern for unusually sensitive people; 101–150 is 'Unhealthy for Sensitive Groups', meaning children, the elderly, and people with respiratory or heart conditions should limit outdoor activity; and 151–200 is simply 'Unhealthy' for everyone.
The main pollutants being tracked are PM2.5 and PM10. PM2.5 refers to fine particulate matter — tiny particles 2.5 micrometres or smaller in diameter. They are so small they can travel deep into the lungs and even enter the bloodstream, making them especially dangerous. PM10 refers to slightly larger particles, up to 10 micrometres, which can still irritate the nose and throat. Both types come from vehicle exhaust, factory emissions, dust, and burning of waste or crops.
Kovvur's readings do not exist in isolation — they reflect a nationwide problem. According to IQAir's 2024 World Air Quality Report, released in March 2025, India's average PM2.5 concentration in 2025 stood at 48.9 micrograms per cubic metre, equivalent to an AQI of 134. That is nearly ten times the World Health Organization's, or WHO's, annual safe guideline of just 5 micrograms per cubic metre. The same report found that only 17% of cities globally meet the WHO air pollution guideline, and just seven countries in the world met the WHO annual PM2.5 threshold.
The data that feeds platforms like IQAir comes partly from India's official pollution monitoring agencies: the Central Pollution Control Board, or CPCB, at the national level, and the Andhra Pradesh Pollution Control Board, or APPCB, at the state level. These bodies operate monitoring stations and enforce pollution norms for industries and vehicles.
Kovvur's air quality is not constant throughout the year. In winter, a phenomenon called temperature inversion — where a layer of warm air traps cooler, pollutant-laden air close to the ground — makes readings worse. During the monsoon months, rainfall washes particulates out of the air, bringing temporary relief. Residents and industries remain subject to monitoring under APPCB norms year-round.
At the national level, the government runs the National Clean Air Programme, or NCAP, which targets a 20–30% reduction in PM2.5 and PM10 concentrations by 2024–26 in 131 cities officially identified as 'non-attainment cities' — places that consistently fail to meet national air quality standards. Kovvur, being a smaller town, is not on that primary NCAP list, which means it may receive less focused policy attention than larger urban centres, even as its residents breathe the same polluted air.
Why it matters
Air quality is a public health issue that affects every person who breathes — and in Kovvur, a town with multiple industrial units and heavy commercial traffic, the risks are real and daily. Readings in the 'Moderate' to 'Unhealthy for Sensitive Groups' range mean that children, elderly residents, and those with asthma or heart disease are already at elevated risk from simply going about their lives. India as a whole is grappling with PM2.5 levels nearly ten times above the WHO safe limit, and smaller towns like Kovvur — which sit outside the government's flagship NCAP programme — risk being overlooked in national clean-air efforts even as industrial growth continues. Understanding local air quality data empowers residents to protect themselves and hold polluters and regulators accountable.
