Arvin interim solutions POU program

Safe Water Sign
If you see this sign next to a water source in the community, it has a POU filter and is safe.


The California State Water Resource Control Board (SWRCB) awarded funds to RCAC to procure, install and monitor point-of-use (POU) arsenic filtration systems throughout the city of Arvin. The POU filters will remove arsenic from the drinking water using carbon block media adsorption technology. The filtered water will then meet safe drinking water standards.

Read this bilingual fact sheet to learn more about the filters and other community water projects. The filtration systems will be located in Arvin where RCAC is installing water bottle filling stations as a part of the Agua4All program as well as additional water access points throughout the Arvin Union School District. A site map is available here. The first filtration systems were installed in May and installation will continue throughout the summer. A rigorous monitoring program to ensure the filters produce safe water will be in place through March 2017. As of August 1, 2017, RCAC and our partners completed installation of  173 POU filters in six schools in three separate school districts including Arvin Union School District, Kern High School District-Arvin High and Grimmway Academy. We have recently supplied more than 200,000 gallons of arsenic free drinking water to 6,000 students in Arvin. Follow the links below to view the filter installation sites for the schools:

This POU pilot program is the first of its kind. Once the pilot is complete RCAC and SWRCB will use the experience to administer similar programs in the future throughout the state. The POU program is part of a larger interim solutions effort going on in Arvin to bring residents safe drinking water now. In addition to the POUs, there will be three safe water vending machines built outside of the Arvin Community Services District (CSD) offices where residents can fill up large water jugs for home use. These interim solutions will provide residents the human right to water while the CSD continues to work toward a long term solution.

Sampling will happen on a rotating monthly basis at sites throughout the community, and as filters come online. As water quality results come in they will be posted here. Note that 10ppb is the legal limit for arsenic in drinking water, which means anything under this amount by state and national safe drinking water standards is considered safe. An ND (non-detect) reading means there is either no arsenic in the water or the amount is so little it is not detected by water testing. The code at the top of each column identifies which fountain was tested. Here is a site acronym key, which outlines site locations and the associated administrative entity.
