- Groundwater may become contaminated without our knowledge.
- WHATEVER its origin, groundwater spends a long time in an aquifer.
- Nitrogen deposition from air pollution (which starts out as NOx or ammonia) is now also sufficient in parts of East Anglia to put groundwater over the EC limit.
- Researchers are now looking at what happens to pesticides and industrial organic solvents, which will probably be the next threat to groundwater quality.
- ENDS noted that around 6 per cent of Severn Trent's abstracted groundwater supplies exceeded 50 mg/litre of nitrate but "with a continuation of present land use practices the figure will rise to 20-;25 per cent by 2011".
- For example, groundwater containing high quantities of iron can produce large amounts of iron precipitates when biological nutrients, such as peroxide or phosphate, are added.
- In most countries, groundwater flows from aquifers throughout the year but rainfall replenishes them for only part of the time.
- In the past 50 years, relative sea levels in Venice have increased by 23cm, largely because of sub-surface layer compaction and sinking as a result of groundwater pumping.
- The product adopted for this task was a laminated bitumen and polyethylene sheet material which demands very careful attention to the formation of joints between sheets if groundwater penetration is to be entirely excluded.
- Sometimes conventional biological reactors are used to clean-up groundwater and/or contaminated soils.
- Groundwater pollution will take place in London on 25-;26 February 1992.
- Other factors, such as pH and temperature, cannot be changed easily in groundwater, but may be adjustable in any above-ground reactors.
- Apart from environmental auditing and impact assessments the company offers other environmental services - air, water and groundwater monitoring; analytical laboratory services; hazards and risk analysis; quality assurance/quality control plans; as well as arranging public meetings and press conference for clients.
