A new study reveals California leads the nation in combined water and air quality challenges that threaten public health.

The research by Nevada-based personal injury lawyers H&P Law analyzed drinking water violations and air pollution levels across all 50 states in 2023. Scores were calculated by combining average drinking water violations and air pollution levels to identify the states where residents face the most significant environmental health risks.

California tops the list with a combined environmental health score of 84.35 out of 100. That’s 52% higher than the national average of 55.40. The Golden State recorded 2.8 average drinking water violations (24.35 score) alongside 12.7 air pollution levels (60.00 score).

Looking at the study, a spokesperson from H&P Law commented, "The findings reveal a troubling reality regarding residents in states like California, who face significant environmental health risks daily.

"Poor water quality and polluted air contribute to respiratory diseases, cardiovascular problems, and other serious health conditions. Strengthening environmental regulations and enforcement can help protect public health and ensure safer communities for all Americans."
