The STL business has a turnover of over £15m and operates from two main laboratories in the UK – in Wakefield and Coventry – as well as a satellite laboratory in Runcorn and a logistics centre in Ireland.  STL employs over 300 staff and has a leading market position in providing analytical services to water authorities in the UK.
