Below is a detailed write up from our ozone expert, John H. highlighting the latest service trip to northern California. Follow along to broaden your knowledge ozone’s impact on groundwater pollutants and the sacred redwood trees of California.
When the winter rains in Northern California fall on the redwood logs and lumber at Schmidtbauer Lumber, tannins from the wood leach out and make the water collection pond look like coffee! The company faces hefty fines for discharging this water back into the environment.


Our rental trailer #10 was being used to remove the tannins and making the water clear again and suitable for discharge. The pond is so good now, a family of ducks lives in it and it has some fish. When the rain stops in the summer, they don’t need it.
Below I am standing in front of a 1800-year-old redwood slab. It started growing only 190 years after Jesus was born, and was cut down in 1943 (see historical timeline)
