All groundwaters contain dissolved salts, derived either from weathering ofthe host rock, from the minute amounts contained in rainfall or fromevaporite deposits. The latter are salt deposits formed at the same timeas the surrounding sedimentary rocks.

The map depicts groundwater salinities measured from individual waterbores.

It shows generally low salinities in the north. In those areas, high rainfall,higher recharge rates and a faster through-flow of groundwater leads toless opportunity for salts to concentrate by evaporation in the soil beforethey are flushed down to the aquifer.

The reverse is true in the arid zone to the south where salinities are highlyvariable and range up to values almost twice the concentration ofseawater (34,000 mg/L TDS). Low salinities observed in the arid zonereflect localised areas of enhanced recharge such as along rivers andfloodouts.

Groundwater usually discharges at low-lying points in the landscape. Itcan take the form of individual springs or as diffuse seepage into streambeds. Recharge to groundwater is greatest in the higher rainfall zone inthe north, so discharge is correspondingly greater.

Many streams in the north maintain a flow for at least part of the long dryseason because of groundwater discharge. Some streams, particularlythose with major karstic or porous rock aquifers in their catchments, flowthroughout the dry season. Springs with significant discharges (more than100 L/s) only occur in karstic aquifers.

Another mechanism for groundwater discharge is where trees in theriparian zone directly tap the watertable. This occurs throughout theTerritory, but in the arid south it is thought to be the dominant processalong with discharge through salt lakes.

This map shows recorded springs and streams that flow throughout thedry season. The streams have been classified according to their flows atthe end of the dry season. The classification only extends to the tidal limit,so some streams such as the Roper River appear to stop before reachingthe coast.

The map shows the most likely range of bore yields that can be expectedfor a particular area. Note that higher or lower yields can be encountereddepending on local conditions.

The higher yields (more than 5.0 Litres/second) occur in fractured andkarstic aquifers.

Most fractured rock aquifers give intermediate yields (0.5 - 5.0Litres/second), while low yielding aquifers include granite and shale.

A relict drainage system that formed in the Tertiary era between 2 and 65million years ago is preserved in the south western part of the Territory. Itcomprises small sedimentary basins and narrow palaeovalleys.

Aquifers are developed in river sands and gravels that form part of thechannel and basin fills. Shallow calcrete layers can host fractured andkarstic aquifers.

Apart from the Ti-Tree Basin and some palaeovalleys in the Tanami desert,few of these deposits have been investigated for their groundwaterpotential.

This map has been compiled from geological maps, satellite imagery andwater bore data. In many places it is highly speculative due to the sparsedrilling in those areas.

This refers to the distance over which groundwater flows through the aquifers from recharge to discharge areas.

Local - less than 5 kilometres Intermediate - 5 to 50 kilometres Regional - more than 50 kilometres

The majority of aquifers in the Northern Territory are developed in networks of fractures (cracks) in hard rocks. Their extent depends on the intensity of fracturing and thedegree to which fractures are connected with each other. Fractures are more commonly open in weathered rock and so more capable of storing and transmittinggroundwater.

The highest yielding zones are often situated at the base of weathered rock. This typically varies between 30 and 80 metres, depending on the region.

Extensive sedimentary basins containing limestone and dolomite support "Karstic" aquifers formed both by fractures and also by solution cavities ranging up to the size ofcaves.

Aquifers that have primary intergranular porosity are formed in both unconsolidated sediments (e.g. river gravels) and in older sandstones. The extents of the former arepoorly known. The Ti-Tree Basin and an alluvial aquifer in the Keep River area are the only "unconsolidated sediment" aquifers shown on the main map. Others are shownon the "Palaoevalleys" side map.
