This paper briefly describes the growth of awareness of cryptosporidiosis in the United Kingdom during the 1980s, up to the outbreak in Swindon and Oxford in 1989.

The paper describes the immediate effect of the Swindon outbreak on North Surrey water quality. It describes the monitoring strategy for cryptosporidium which has been developed in North Surrey, and in associated companies in the same group ownership, and ends by describing the administrative arrangements for the regulation of prices and water quality for England and Wales, with particular reference to cryptosporidium.
