[ARCHIVED] Recommendation is to discontinue the “Nova Scotia Groundwater Observation Well Temperature Data”. This is for scientific / technical reasons. The data was never designed to be collected as a dataset on its own, but is used by sensors to create a correction facter for other data (groundwater levels). Developments in academic research show that the type of water wells we monitor for groundwater levels do not have the correct design for measuring temperature, with issues that include the potential within wells for thermal convection cells that cause groundwater temperature readings to fluctuate inconsistently.

Groundwater temperatures have been recorded from the NS Groundwater Observation Well monitoring network since 2003. This temperature data is presented as daily averages and may be influenced by a number of variable factors including air temperature, well construction, depth, geology and groundwater conditions.

The Department of Natural Resources and Renewables (NRR) (formerly the Department of Energy and Mines) and Nova Scotia Environment and Climate Change (ECC) maintains an electronic Well Log Database which contains water well construction and location information for water wells in the Province of Nova Scotia. Information in the database is entered from original paper copies of well logs that are submitted by certified well drillers and well diggers to ECC. This version of the database was extracted on January 5, 2022 and contains 125,517 well logs constructed between 1940 and 2021, inclusive.

The Departments of Natural Resources and Renewables and Nova Scotia Environment (NSE) maintains an electronic Well Log Database, which contains water well construction and location information for water wells in the province of Nova Scotia. Information in the database is entered from original paper copies of well logs that are submitted by certified well drillers and well diggers to NSE. The database currently contains approximately 115,500 well logs constructed between 1940 and 2012, inclusive.

A GIS-based approach for broadly evaluating the relative vulnerability of bedrock coastal aquifers to seawater intrusion in unserviced areas of the province was developed. The approach uses available provincial spatial datasets, such as digital elevation models, civic address points and well logs data, to evaluate relative vulnerability based on the following derived criteria: distance to the coast, land slope, development density, non-residential groundwater use and static water level.
