Data of the risk of Potential Acid Sulfate Soil (PASS) materials being disturbed by land development activities based on the likelihood of PASS materials occurring within 3m of the ground surface for Geraldton. This data is designed for use by planners to assess whether development applications for specific sites require additional conditions on the basis of whether normal land development activities carry a risk of disturbing PASS materials. Disturbance risk is rated on the basis of the likelihood of PASS materials being encountered within 3m of the ground surface should this depth of soil be disturbed in any way. The depth of 3m is considered since this was regarded as the depth that most soil disturbance activities would extend during in most land development processes. Disturbance activities in this context include drainage, excavations and dewatering. For further information phone the Contaminated Sites hotline 1300 762 982. This dataset was formerly known as Acid Sulfate Soil Risk Map, Geraldton (DER-009). This dataset is no longer actively maintained by DWER.

Predicted risk of Acid Sulfate Soil (ASS) materials occurring within shallow soil layers in WA Estuaries (not covered by other Department of Environment ASS risk datasets) that could be disturbed by normal land development activities (drainage, excavations, dewatering). This map was developed to assist planners in assessing whether development applications require additional conditions for developments of sites where there is a risk disturbing or draining ASS/PASS. No distinction is made between potential and actual sites since the risk for further environmental degradation from disturbance or drainage is similar.

This dataset is no longer actively maintained by DWER.

Site classifications and expert profile summary assessment based on ASS soil coring information obtained during the 2003-2005 acid sulfate soil mapping program covering low lying landscapes from the Peel-Harvey to Dunsborough, Scott Coastal Plain and Albany-Denmark region. Includes associated site data collected during mapping program and data derived from ASS evaluation. Content Purpose: Brief summary of the variables contained within the ASS evaluation dataset. For further information phone the Contaminated Sites hotline 1300 762 982. This dataset was formerly known as 2003-2005 ASS Site Evaluation (DER-007).

This project has mapped the occurrence of Acid Sulfate Soils (ASS) along the coast of NSW and provides information that will assist land management and rehabilitation. In their natural state, these soils are submerged but when exposed or drained, they become oxidised and sulphuric acid is produced. This reduces soil fertility, kills vegetation and reduces fish populations. The identification of the location and extent of potential acid sulfate soils (PASS) is the essential first step in managing this problem. 128 map sheets were mapped for risk of occurrence of ASS at a scale of 1:25,000. This project was co-funded by the Natural Resources Audit Council (NRAC), and was revised in 1997. In this version, (v2.5.1), ASS risk maps have not been remapped, however minor attribution changes to the GIS linework have occurred to fix errors and some additional original information has been incorporated into the attribute tables. This data provides maps of elevation, landform process groups and landform elements for the mapped area. The symbology for the ASS probability risk map classes can also now be simplified to reflect only probability, potential depth from the surface and presence of areas with Pleistocene sediments or ASS scalding. Related Datasets: The dataset area is also covered by the mapping of the Soil and Land Resources of Central and Eastern NSW and Soil Landscapes of Central and Eastern NSW and Hydrogeological landscapes of NSW. Online Maps: This and related datasets can be viewed using eSPADE (NSW’s soil spatial viewer), which contains a suite of soil and landscape information including soil profile data. Many of these datasets have hot-linked soil reports. An alternative viewer is the SEED Map; an ideal way to see what other natural resources datasets (e.g. vegetation) are available for this map area.
