I became a Chartered Scientist in 2013 when the Institute of Water first introduced professional registration for scientists. I studied Marine and Freshwater Biology as a first degree but was first introduced to the water industry when my father started working at a local Water Treatment Works and I assisted in the laboratory at the works every summer holiday whilst doing that degree carrying out chemical and microbiological testing of treated water samples.
