	===What does groundwater development involve?===		===What does groundwater development involve?===

	Developing groundwater for water supply can involve ~~various~~ different activities~~, depending on the hydrogeological environment, how much groundwater is needed and what it will be used for~~. ~~It is usually also important~~ to ~~develop groundwater sources '''sustainably''', so that the groundwater resource is protected and maintained for future supplies.~~		Developing groundwater for water supply can involve many different activities. What needs to be done depends heavily on:

	~~At its simplest~~, groundwater ~~flowing naturally from a spring can be directly tapped with very little effort, although protecting that spring, so that the water doesn~~'~~t become polluted, can be more difficult. In another simple example, where groundwater levels are shallow~~ and ~~the aquifer is easy to dig through (e.g. sand or gravel), hand dug wells can be quite easily constructed to allow groundwater to be abstracted~~ - ~~but again, protecting~~ the ~~groundwater in the well from pollution can~~ be ~~more difficult~~.		:- the hydrogeological environment,
			:- how much groundwater is needed' and
			:- what the water it will be used for.

	~~Where the aquifer and/or~~ groundwater ~~levels are deeper~~, or the ~~aquifer can't be easily dug through by hand, developing~~ groundwater ~~resources~~ is ~~more complicated. It is likely to need some kind of mechanical drilling - either manual drilling, or using a drilling rig~~.		It is usually also important to develop groundwater sources '''sustainably''', so that the groundwater resource is protected and maintained for the future.

	~~In areas where the aquifers are all permeable and productive, water boreholes~~ can ~~often~~ be ~~drilled just about anywhere~~. ~~But in areas with low permeability and/or complex aquifers~~, ~~or where there are groundwater quality issues~~, ~~new boreholes and wells must be sited and designed carefully if they are to be successful. To do this~~, ~~it's~~ important ~~to understand how groundwater exists~~ and ~~behaves in the area~~.		The simplest kind of hydrogeological environment to develop is groundwater flowing naturally from a spring. This can be directly tapped with very little effort. However, protecting the spring, so that the water doesn't become polluted, is important and is not always as easy.

			Another quite simple hydrogeological environment is where groundwater levels (the water table) are shallow and the aquifer is easy to dig through (e.g. sand or gravel). Here, hand dug wells can be quite easily constructed to allow groundwater to be abstracted - but again, protecting the groundwater in the well from pollution is important and has to be done carefully.

	~~===Resource pages on~~ groundwater ~~development techniques===~~		More complicated hydrogeological environments are where the aquifer and/or groundwater levels are deeper, or the aquifer can't be easily dug through by hand. Here, developing groundwater resources is more complicated. It is likely to need some kind of mechanical drilling - either manual drilling, or using a drilling rig. In areas where the aquifers are all permeable and productive, water boreholes can often be drilled just about anywhere. But in areas with low permeability and/or complex aquifers, or where there are groundwater quality issues, new boreholes and wells must be sited and designed carefully if they are to be successful. To do this, it's important to understand how groundwater exists and behaves in the area.
