The confined sand and gravel layers beneath parts of the southern Sunshine Coast are generally known as the Gibsons and/or Langdale Aquifers. The layers are discontinuous and form individual pockets and lenses of poorly consolidated sedimentary rock and has been identified beneath Chaster Creek, the Town of Gibsons, Gibsons Harbour, Church Road, Granthams Landing, Hopkins Landing, Langdale Creek and the community of Langdale itself.
Where the sand and gravel has been charged with fresh water the layer is artesian in nature. What is an aquifer? Why are some aquifers artesian? How was the aquifer formed and where does the water come from? Are these aquifers the best solution to our now-annual potable water shortages? What are some potential longer-term solutions - more exploratory drilling or more open reservoirs?
These questions and more will be explored in a presentation by Peter Hews on Friday, Jan. 5 at the Sunshine Coast Natural History Society (SCNHS) meeting.
Peter Hews is a semi-retired geologist and member of the SCNHS. He has offered 10 (and counting) annual geology summer field trips for the SCNHS and has presented geology-themed courses for the Sunshine Coast Elder College for the past eight years.
The Sunshine Coast Natural History Society is a local group interested on the natural history of British Columbia and the world. Monthly meetings are held on the first Friday of the month for most of the year. Our society is pleased to present this virtual event.
