In addition to these areas the division will offer a full range of other services, including weed cutting; emergency aeration;

aquatic planting and management;

soft revetment installation;

dredging works and the removal of flotsam and jetsam.

Land & Water Special Projects are the UK agents for an American bacterial product called LLMO (liquid, live micro-organisms), a 'bio-manipulation' product consisting of a range of natural bacteria which, when introduced to eutrophic waters, 'out-compete' the undesirable algae for the nutrients they require, thus restoring the water's quality.

Land & Water says these services are available as one-off contracts or tailor made maintenance packages; they can also be combined for complete or partial restoration projects.

Land & Water Services Ltd has also launched a new division expanding its remediation technologies following the successful completion of recent contracts throughout the UK.

The new division commenced trading on 1 January and will specialise in stabilisation and solidification techniques, particularly with respect to contaminated dredgings, sludges and settlement lagoon arisings.

Other technologies include blending and dilution of low-grade contamination for secondary uses.

Land & Water says its process plants all carry Mobile Waste Management Licence issued by the EA or SEPA and are supervised by personnel holding Certificates of Technical Competence issued by WAMITAB.

As a further means to develop and expand their technologies and markets, Land & Water Remediation has entered into a two-year research programme with the Centre of Contaminated Land Remediation at the University of Greenwich. An Associate has been specially employed by the partnership and a postgraduate research programme agreed between the two parties which will expand their knowledge of 'Stabilisation & Solidification' with particular regard to salt-water as well as fresh-water contamination.

Bill Gush is managing the new division and says that one of Land & Water Remediation's aims is to reduce the amount of contaminated material being sent to landfill sites and to increase the secondary use of contaminated silts and sludges by using stabilisation and solidification technology.

Recent successes have included the reuse of stabilised contaminated silts from the Forth & Clyde Canal as engineering backfill and revetment material, the blending of contaminated dredgings from the River Yare as a bank raising material and the blending of contaminated dredgings from the Coventry Canal with a quarry waste to form a restoration material.
