How Think Blue is Improving water quality
Think Blue San Diego takes action year-round to help stop pollution before it starts and keep the City of San Diego in compliance with state and federal water-quality regulations. Those actions include street sweeping, business and residential inspections, storm drain cleanings and water-quality monitoring, among other things.
The performance of those activities results in the collection of data that the City uses to make data-driven decisions to improve water quality and prevent pollution. Check out our interactive map below to Analyze the data for the 2024 Fiscal Year and past years to see what’s happening in your neighborhood.
