We gradually learned that Delhi’s true menace came from its air, water, food and flies. These perils sicken, disable and kill millions in India annually, making for one of the worst public health disasters in the world. Delhi, we discovered, is quietly suffering from a dire pediatric respiratory crisis, with a recent study showing that nearly half of the city’s 4.4 million schoolchildren have irreversible lung damage from the poisonous air.

And children are by no means the only ones harmed. Many adults suffer near-constant headaches, sore throats, coughs and fatigue. Arvind Kejriwal, Delhi’s chief minister, had to leave the city for 10 days in March to cure a chronic cough.
It’s not just the air that inflicts harm. At least 600 million Indians, half the total population, defecate outdoors, and most of the effluent, even from toilets, is dumped untreated into rivers and streams. Still, I never thought this would come home to my family quite as dramatically as it did.
We live in a four-year-old, five-story apartment building that my wife chose because its relatively new windows could help shut out Delhi’s appalling nighttime air. Its cookie-cutter design — by the same developer who built dozens of others in the neighborhood — gave us confidence that things would function, by no means assured for new construction here.
About six months after we moved in, one of our neighbors reported that her tap water suddenly smelled like sewage. Then the smell hit another neighbor and another. It turned out that the developer had dug open channels for sewage that had gradually seeped into each apartment’s buried water tank. When we pulled up the floor tiles on the ground floor, brown sludge seemed to be everywhere.
I was in the shower when this sewage mixture arrived in our apartment. Sounds horrible, but I shrugged and toweled off because that smell is such a frequent presence here.
For much of the year, the Yamuna River would have almost no flow through Delhi if not for raw sewage. Add in the packs of stray dogs, monkeys and cattle even in urban areas, and fresh excretions are nearly ubiquitous. Insects alight on these excretions and then on people or their food, sickening them.
Most piped water here is contaminated. Poor sanitation may be a crucial reason nearly half of India’s children are stunted.
The list of health threats sounds harrowing when considered together, but life goes on and can be quite nice here. Our apartment building eventually installed aboveground water tanks. My children’s school and travel in the region are terrific, and many expats are far more influential here than they would be in their home countries.
Yet one afternoon this spring, someone in our neighborhood burned something toxic, and an astringent cloud spread around our block. My wife was out walking with a friend, and their eyes became teary and their throats began to close. They bolted back inside our apartment where they found Bram gasping again, for the first time in two years. In some places in Delhi, the levels of fine particles that cause the most lung damage, called PM2.5, routinely exceed 1,000 in winter in part because small trash and other fires are so common, according to scientists. In Beijing, PM2.5 levels that exceed 500 make international headlines; here, levels twice that high are largely ignored.
