When residents of Watts, one of Los Angeles's most historically marginalized neighborhoods, learned that samples of their drinking water contained elevated levels of lead, it triggered a unanimous 10-0 vote by the Los Angeles City Council demanding an immediate investigation by the Department of Water and Power (LADWP) and the city's Housing Authority. A study had found alarming lead concentrations across 21 water samples in the area. Councilman Tim McOsker, who represents the 15th District covering Watts, introduced the motion. City officials expressed shock. Residents were told they would be communicated with about progress.
What did not follow — swiftly enough — was the kind of urgent, comprehensive remediation that the severity of lead contamination demands. Lead is a neurotoxin with no known safe level of exposure. In children under six, even low-level lead exposure causes irreversible cognitive damage: lower IQ, learning disabilities, behavioral disorders, and reduced academic achievement. The damage is permanent. There is no antidote. Prevention is the only cure. And in Los Angeles — the second-largest city in the United States — the infrastructure delivering that water to millions of residents is, in many neighborhoods, decades old and chemically compromised.
