How could Aecon's gravel quarry application in Alberta affect Southern Alberta?
Quarry proposal may risk contaminating Southern Alberta's water sources If the Summit Quarry is approved, the operation could significantly alter the local hydrology and risk contaminating water sources in Southern Alberta. Opponents argue that removing 25 metres of topsoil and gravel would leave only one metre of material atop the creek’s aquifer. This exposure could allow seeping arsenic, chromium, selenium, and hydrocarbons to enter the creek and threaten local water wells. The environmental concerns center on the permanent alteration of the natural equilibrium and the potential disruption of the spring’s year-round flow.

How it reaches Southern Alberta
-
Aecon applied for approval for a gravel quarry operation in Alberta. A hearing was held regarding the pit, known as the Summit Quarry, which opponents argue threatens Big Hill Springs Provincial Park. The provincial government had previously granted Water Act approval for an 81-hectare proposal by Aecon in July 2023.
The full event1independent outlet -
Opponents warn that the quarry activity would remove 25 metres of topsoil and gravel, leaving only one metre of material atop the creek’s aquifer. This change risks exposing the creek to seeping arsenic, chromium, selenium, and hydrocarbons, which could threaten local water wells and the region's water integrity.

Why it matters
The integrity of local water sources is at stake for the region. The proposed quarry operation involves stripping away 25 metres of topsoil and gravel, which opponents argue permanently alters the natural equilibrium of the area. This change could compromise the creek’s aquifer and threaten the water supply for local landowners and the provincial park.
This debate reflects a broader conflict between resource extraction and environmental preservation in Alberta. While proponents argue the project is adequately protective and appropriate, opponents cite scientific concerns regarding the chemistry of the water and the potential for toxins to be released when the gravel is exposed.
What we don't know yet
- Will the Environmental Appeal Board reverse or amend the July 2023 Water Act approval?
- What specific measures will be implemented to prevent the release of toxins into the creek?
