Casa Nova's air quality reflects the Bahia semi-arid São Francisco River valley at the Pernambuco border, with vehicle emissions from the BR-235 and the surrounding irrigated fruit farming and hydroelectric operations on the Sobradinho reservoir contributing local sources. The São Francisco valley's winds provide reasonable ventilation, while drought conditions and Caatinga burning contribute seasonal PM10 and the Sobradinho reservoir's large water body provides humidity that moderates the extreme dust events typical of drier Sertão regions.
