NID releases its annual Water Quality Report
The Nevada Irrigation District continues to provide drinking water that meets or exceeds all state and federal public health standards.
The District has released its Annual Water Quality Report, also known as the Consumer Confidence Report, which summarizes water quality monitoring and testing conducted during the 2025 calendar year.
The report focuses on water supplied through the Elizabeth L. George, Loma Rica, Lake Wildwood, Lake of the Pines, and North Auburn water treatment plants.
In 2025, the District treated and distributed more than 2.9 billion gallons of surface water. This water originates as Sierra Nevada snowpack and is delivered through a network of canals and pipelines to NID’s water treatment plants.
In addition to operating and maintaining a safe and reliable drinking water system, NID conducts routine water quality testing throughout its distribution system to ensure drinking water continues to meet all state and federal requirements.
The report includes results for a wide range of constituents, including microbial contaminants (such as viruses and bacteria), inorganic contaminants (such as salts and metals), pesticides and herbicides, organic chemical contaminants (including synthetic and volatile organic chemicals that are by-products of industrial processes and petroleum production), and radioactive contaminants.
NID’s Water Quality Report is an important part of the public’s right-to-know, as established in the 1996 Amendments to the Safe Drinking Water Act (SDWA, Section 1414(c)). Federal regulations (63 FR 44511, August 19, 1998) require community water systems to provide this annual report.
