"Thermoplastic Piping Systems for Demanding Services". Lecture given at the International Meeting on Chemical Engineering and Biotechnology, ACHEMA Frankfurt/Main, Germany, June 6, 1988.
I called on Dr. Constantin Gehriger because one of the soil analysis samples contained Arsenic at 0.41 parts per million, which exceeded the level of 0.38 ppm as recommended by the Environmental Protection Agency I was advised to consult a toxicologist and have him perform a toxicological risk assessment in order to address the potential risk associated with the planned site use. So, I hired a professional toxicologist. But because of the importance of the project and the sensitivity of the population to environmental issues near the Pacific Coast I wanted a second opinion. This is why I talked to Dr. Constantin Gehriger He reviewed the soils reports, repeated the analytical measurements, and negotiated with the responsible government agencies. He looked at the theoretical models of the EPA recommendations and backed up his conclusions with actual case studies. He concluded that: "The traces of Arsenic found on the School site constitute no health risk". He arrived at the same final conclusion as the professional toxicologist that I had hired earlier. I found Dr. Gehriger to be extremely thorough and methodical in his processes and analysis and would recommend his services highly. From David L. Robison, Strategic Construction Management, Santa Cruz CA, July 2000"
