Well UTMs estimated from map or site plan showing approximate well location.ĭ1 = Centroid of Property using Nova Scotia Property Registration Database (NSPRD) Well locations have also been identified based on available reporting (e.g. These UTMs were taken directly from the coordinates reported on the original well logs from 2004-2006, whereas the well logs entered after 2006 were subject to QA/QC. Note that the UTM coordinates of wells constructed after 2004 have been recorded by well contractors using handheld GPS units (well drillers only). Well UTMs estimated using GPS or survey equipment. The following ten codes are used in the database: This field indicates the georeferencing method used to assign UTMs to the well logs. The method used is recorded in the Georef M field, the source of the data is recorded in the Georef S field, and the associated accuracy of the UTM is recorded in the Georef A field. UTM coordinates in the database have been approximated based on the various levels of available georeferencing accuracy. Northings and eastings are in NAD83, zone 20 metric units. GLTPC: Glaciolacustrine/Till Plains/Colluvial HC: Undifferentiated Hadrynian-Cambrian rocks G: Unknown (likely Goldenville Formation) Storativity = Aquifer storage coefficientĭC: Undifferentiated Devonian-Carboniferous rocks Q20 (l/min) = Potential long-term pumping well yield, Litres per minute Q20 (m3/d) = Potential long-term pumping well yield, m3/d Tapp (m2/d) = Apparent transmissivity, m2/d ![]() Total Recovery (m) = Total water level recovery, metres Max Draw Down (m) = Maximum drawdown, metres Static (m) = Depth to static water level, metresĪverage Rate (m3/D) = Average pumping rate, m3/dĪvailable Draw Down (m) = Available drawdown, metres Note that the value -9999 in the data table denotes a null value. Information recorded in the database includes details about the well construction and pumping test, and the interpreted hydrogeological properties. The Nova Scotia Pumping Test database is maintained by Nova Scotia Department of Natural Resources and Renewables (NRR)Īnd contains an inventory of pumping tests submitted to the province, typically in support of a water withdrawal approval application.
