SUMMARY:IAH - June Tech Talk
DESCRIPTION:Title: Unmasking Groundwater Signals in an Urban Estuary\n\n\n\nPresented by: David Harris \nProduced by: IAH NSW \nDate: Tuesday 10 June 2025\nTime: 17:30 for an 18:00 start\nWhere: WSP Office – Level 27\nOnline: Teams link \nAbstract: \nUrban estuaries represent highly dynamic and intricate environmental systems\, characterized by the confluence and mixing of freshwater from riverine and groundwater sources with saline tidal inflows. This complexity is further amplified by episodic\, and often contaminant-laden\, stormwater runoff\, a hallmark of urban landscapes. Each of these contributing water sources possesses distinct chemical signatures; however\, these signatures frequently overlap\, particularly in environments subjected to extensive anthropogenic pressures. The task of isolating and quantifying the groundwater component\, often referred to as Submarine Groundwater Discharge (SGD) when it enters estuaries\, is of paramount importance to quantifying catchment dynamics. Understanding SGD is critical for accurately assessing nutrient budgets\, delineating contaminant transport pathways\, and evaluating the overall ecological health and resilience of estuarine ecosystems. The process of urbanization introduces a wide array of anthropogenic contaminants into the hydrological cycle\, profoundly altering natural geochemical baselines and making the differentiation of water sources a formidable challenge. The very nature of urban development\, with its impervious surfaces and modified drainage networks\, often leads to what can be termed an “urban geochemical signature”. This talk will explore the potential for using standard water quality parameters (trace metals\, major ions\, nutrients\, and physico-chemical parameters) to differentiate groundwater from tidal inflows\, freshwater (riverine) inflows\, and stormwater runoff within the context of an urban estuary. \n  \nBio: \nDavid is a hydrogeologist and water management specialist with fifteen years’ experience in environmental consulting. David graduated from the University of Plymouth (UK) in 2009 with a Masters in Geology and subsequently went on to complete a Masters in Hydrogeology from Newcastle University (UK). During his career David has worked throughout Australia and the UK supporting groundwater\, surface water and contaminated land projects; providing advice on contaminant fate and transport\, groundwater-surface water interactions\, dewatering-discharge assessments\, environmental licensing\, remediation\, and integrated water management. David has spent the past 9 years based in Sydney\, NSW\, where he has contributed technical advice to delivery of major construction projects including the M6\, M8\, Sydney Metro Tunnelling Packages\, WestConnex\, and Western Sydney Airport. David is Certified Environmental Practitioner and Director of Hydroview Consulting\, a specialist water advisory consultancy based in Sydney\, NSW. In his spare time David enjoys the trials of gardening\, and home hydroponics.

SUMMARY:IAH NSW - November Tech Talk
DESCRIPTION:The role of evidence and groundwater expertise to support decisions of the Land and Environment Court of NSW\nPresented by: Sarah Bish \nProduced by: IAH NSW \nDate: Tuesday 11 November 2025\nTime: 17:30 for an 18:00 start\nWhere: WSP Office – Level 27\nOnline: To be provided closer to the date \nAbstract \nAppeals before the Land and Environment Court of NSW can range from development applications\, noise complaints\, building defects\, tree disputes\, valuation for compensation\, and Aboriginal land claims. As a Commissioner\, you are required to be able to determine in a hearing all these matters. Having technical specialists as Commissioners is a unique quality of the Court that is written into its legislation. Appearing before a Commissioner or Judge of the Court can be daunting\, and if unprepared\, the expert and their evidence will be challenged. Understanding what the Commissioner and the Court is expecting from an expert will help in preparing the appeal and evidence for the Court to consider\, and also appearing confidently before the Court in a hearing. \nBio \nSarah Bish is a qualified geologist and hydrogeologist with over 35 years working in the NSW public service\, private sector and United Nations. Currently\, she is the Principal Hydrogeologist with the NSW Department of Climate Change\, Energy\, the Environment and Water\, and more recently she was a Commissioner of the Land and Environment Court of NSW. Sarah Graduated with a Bachelor of Applied Science (Geology) and a Master of Applied Science (Groundwater Management). She has an Advanced Diploma in Business Management\, and has been accredited as mediator and in project management. Her expertise is in hydrogeology\, water resource management\, water/sanitation engineering\, disaster and emergency response\, and compliance. Internationally\, Sarah as worked in the USA\, Lebanon\, Papua New Guinea\, Uzbekistan\, Turkmenistan\, Western Sahara\, Algeria\, Macedonia\, Malaysia and Iran\, primarily on emergency response.
