Improving Water Quality: By the Numbers

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. Analyze the data and find out what’s happening in your neighborhood.
