Water. Many factors must be considered to obtain representative samples of water. The most important are the pollutant and the point at which it entered the aquatic environment. Pollutants can be contributed by agricultural, industrial, municipal, or other sources, such as spills from wrecks or train derailments. The prevailing wind direction and speed, the velocity of stream or river flow, temperature, thermal and salinity stratification, and sediment content are other important factors. 

The natural degradation of wooden shipwrecks in-situ can be slowed down, or even eliminated, by covering the site with a physical barrier such as polyethylene or polypropylene textile (Figure 15). This method is very effective because it uses the wrecked environment to create an overlying mound of sediment, which becomes part of the site. It also physically prevents colonisation of any subsequently exposed wreck timbers by wood-boring animals, like shipworm. 

Reburial of waterlogged wood in the marine environment is now becoming increasingly common practice in managing wooden historic wrecks in situ, predominantly due to the prohibitive conservation costs. Remedial strategies that are appropriate and cost-effective are fundamental pre-requisites for the successful long-term management of underwater wreck sites. 

Continual safety improvement Continuoussafety improvement means constantly reviewing, revising, and evaluating your work processes and established safety procedures. It means establishing a corporate environment that is committed to, and focused on, safety for all employees — which will translate into less people getting hurt, and vehicles getting wrecked. ...

Single-unit tank cars are protected from excessive internal pressure by a spring-loaded pressure relief valve located on the manway cover plate. Excess flow-check valves are installed on the liquid eduction and vapor lines of many tank cars in compressed gas service. These excess flow valves are intended to contain the tank contents in transit, in a wreck environment if the valve is sheared off, or during other incidents when uncontrolled release of product may occur.

In 1989, the ship Perenits was wrecked during a storm on the French coast. The cargo included 5.8 tons of lindane, 1 ton of permethrin, and 0.6 tons cypermethrin. If these had been discharged into the marine environment, which would have been the most damaging, and why Fortunately, only 1 container of lindane was lost. What would be likely its effect on the marine environment ...
