The current status of small but important water bodies such as creeks in Contra Costa County is unclear. A variety of impacts can cumulatively stress our urban creeks and other aquatic systems and impair their beneficial functions. Nonpoint source pollution from the land that can flow into creeks include sediment, synthetic compounds from our roads and automobiles and nutrients from fertilizers, sewage leaks, and animal waste. Creek monitoring helps to identify potential problems and can provide information useful for addressing these problems. Underserved student populations can train as interns to acquire valuable surveying/monitoring and other green-job related skills.
