Water Pollution 101
Our Future Depends on Clean Water
Access to clean water is important for our safety and vitality. Stormwater management is critical to prevent water pollution and ensure the health of our ecosystems.
There are two main types of pollution:
Non-Point source water pollution refers to pollution for which the source is difficult to identify. It occurs when precipitation collects pollutants on the ground as it makes its way to our local waterways.
Point source water pollution occurs when the contaminant comes from a single obvious source, like an industrial factory or municipal wastewater treatment plant.
How Does Stormwater Pollution Occur?
A watershed is all the land area that drains into a stream, river, lake or other body of water. Stormwater runoff – rainfall that does not soak into the ground, but instead flows over the land into these surface waters – is important to replenish our water supply, but can also harm our watersheds if pollutants are collected along the way.
The Metro Water District's Plan to Manage Stormwater
The Metro Water District considers many strategies to develop a comprehensive regional program that protects our water quality and promotes watershed health.
The Watershed Management Plan includes five model ordinances required of all local jurisdictions as well as regional and state policy recommendations. Additional measures to be implemented by cities and counties within the Metro Water District cover:
- watershed planning and conditions assessment
- land development
- stormwater asset management
- pollution prevention
- public awareness
Metro Water District partners have worked aggressively over the past five years implementing these management measures. All local governments within the 15 counties have passed a version of their required ordinances at the local level. During 2014, more than 50 percent of local governments within the Metro Water District took steps to improve watershed health such as carrying out stormwater projects, applying for grants or prioritizing watersheds to receive projects.Learn more
