Most of Morton's (and Edgar Morton and Partner's) hydrogeological work was concerned with public water supply but he also acted as a consultant for private cases, from the supply of drinking water to individual farms to the industrial scale water requirements of major companies such as Imperial Chemical Industries and Whitbread Breweries.
The bulk of the material relates to Morton's support in applications to bore for water under Section 14 of the Water Act, or opposition thereto, and to general advice on augmentation of local water supply. Most of the projects relate to sites in the north-west of England, though there are also cases in the Midlands and southern England. Little of the material post-dates Morton's death in 1973, although there is material 1978-1991 relating to water supply to British Nuclear Fuels' Chapelcross Power Station.
The material was found in Morton's envelopes and folders, labelled by client or, occasionally, by project. It is presented in alphabetical order following the outline listing.
The material may include correspondence, plans and maps, draft and final reports, borehole logs, drilling logs, rainfall records, rock test data, calculations, tender documents, photographs, etc. Correspondence and key documents relating to any given project were generally kept in reverse chronological order and this arrangement has been retained.
Where there is significant material relating to a collaborating engineering, surveying or similar company, this is indicated in parentheses.
