San Diego County leaders announced Thursday they have a plan to help reduce toxic sewage pollution in the Tijuana River Valley and measure its impact on residents’ health. At a news conference from the river valley, Supervisors Paloma Aguirre and Terra Lawson-Remer said they want the county to use reserves typically set aside for emergencies for two initiatives they estimate would cost $4.75 million. The proposal to use rainy-day funds for Tijuana River sewage efforts is the latest Aguirre has made this week. On Tuesday, she suggested using $19.25 million to buy more air purifiers for residents and air monitors for the county to record real-time data of hydrogen sulfide levels and to run a treatment pilot program that would improve the river water’s conditions.
