Mostly because of all the wood-stoves in the San Lorenzo Valley, Santa Cruz county has once again received a grade of “F” for its air quality. The American Lung Association reported 12 days of unhealthy air, based on monitoring particle pollution from 2014 to 2016, down from 37 days four years ago — however, that’s not enough improvement to warrant a better grade. Santa Cruz county began getting a failing grade in 2015 after a new air monitor documented the pollution problem in San Lorenzo Valley. There are 4 seasonal monitors that are at Cal-Fire In Felton, San Lorenzo Valley Middle School In Felton, Zayante Fire Station And Boulder Creek Fire.
