HOW CAN YOU HELP?
The Mexican government has continued to stay silent on the issue of sewage contamination along the Tijuana River and Pacific Coast. The United States has acknowledged the problem and dedicated funds to mitigate the effects of cross border pollution in the US. However, both countries are just now learning the extent to which the issue of sea spray aerosols (water molecules driven into the air by breaking waves) has effected their border communities.
In Tijuana, air and water monitoring has become spotty and unreliable for community members who are looking to find out more information about the quality of their beaches and neighborhoods. Without the ability to test air quality, or count on their government to do so, many residents risk unhealthy exposure to sea spray aerosols that contain high levels of fecal matter, pesticides, and pharmaceuticals.
PurpleAir is a network of community science sensors throughout the world that monitor particles in the air. PurpleAir sensors are low-cost, easy to install, they only require a power outlet and WiFi, and they automatically transmit their collected air quality data to a global map (pictured below). By using these devices, community members can ask questions and interpret data to better understand the impact of these small particles on themselves, their community, and their environment.
The NSF Center for Aerosol Impacts on Chemistry of the Environment at Scripps Institution of Oceanography has put together a list of organizations, non-profits, and educational centers throughout Tijuana & Imperial Beach that have expressed interest in attaining a PurpleAir Sensor for monitoring and educational purposes.
All funds donated, will be used to purchase PurpleAir sensors for these community groups.
You can also support these community groups directly though the Climate Kids Mexico initiative, a program of the Climate Science Alliance, that works to educate students in the Northern Mexico and Baja California region on the impacts of climate change through the use of hands on science, storytelling, and art.
