His best opportunity was to work as a junior assistant chemist at a large sewage treatment works where his employers expected and encouraged him to study part time. As a qualified professional, he subsequently made his career in water pollution control, largely in the field of wastewater management, working in UK plus seven foreign countries where he encountered many different attitudes to water pollution control.lihat lebih sedikit
