New River Water Quality Data
The California Regional Water Quality Control Board is committed to providing water quality data to the public. Although this data has been reviewed, it is still subject to change.
This data was collected by Regional Board staff pursuant to an agreement between the United States Environmental Protection Agency (USEPA) and the State Water Resources Control Board.
The primary objectives for the sampling program are:
- Monitor and record water quality changes in the New River, as indicated by key indicator parameters;
- Help determine the effects (on the water quality at the International Boundary) of the infrastructure improvement projects in Mexicali, B.C.;
- Help determine the extent of New River pollution and conformance with water quality standards and treaty agreements;
- Obtain information that may be used in the development of more detailed studies, including Total Maximum Daily Loads for the New River.
