Description

Research has shown that in Alberta, the amount of phosphorus in streams increases with agricultural intensity in watersheds. The goal of the Alberta Phosphorus Watershed Project was to determine if wide-spread adoption of environmental beneficial management practices would improve water quality at the watershed scale, as well as to develop the Alberta Phosphorus Management Tool. This report supplements the previously published 2013–2017 Alberta Phosphorus Watershed Project progress report by summarizing the results and progress of the Alberta Phosphorus Watershed Project from 2018–2020.

Description

Highlights work done by the Alberta Phosphorus Watershed Project between 2013-2017. The purpose of the project was to determine if widespread adoption of agricultural beneficial management practices would improve water quality at the watershed scale, and to develop the Alberta Phosphorus Management Tool as a means to identify highest risks for phosphorous loss. Results are presented in a detailed technical science report and an overview and key findings fact sheet.

Description

Dissolved gases in well water are a common occurrence in Alberta. The major gases found in wells are methane, carbon dioxide, nitrogen and hydrogen sulfide. Information on hydrogen sulfide, a gas with a rotten egg odour, is discussed in Agrifacts 716 (D14) Removing Hydrogen Sulphide from Water, so hydrogen sulfide will not be discussed in this publication. Common problems with methane and carbon dioxide are “spurting” taps and priming problems (gas locking) in pumps. The gas problem varies in severity – from occasional “spurting” from the hot water taps to a constant flow of gas from the well casing.

Description

Nitrogen is an essential nutrient for crop growth. Insufficient nitrogen for growing plants can limit crop production. Soil organic matter, chemical fertilizers and livestock manure are sources of nitrogen for crop production. Excess nitrogen not used by growing crops coverts to nitrate (NO3-), which can be very mobile in soils. Nitrate can leach through the root zone and contaminate shallow groundwater. Areas with coarse or sandy soils are at greater risk for nitrate leaching to groundwater. Nitrogen can also be carried in runoff and can contaminate surface waters. Nitrogen must be managed properly to increase crop yields and protect water quality. Manure is a valuable source of nitrogen on the farm; however, nitrogen from manure and chemical fertilizers can pollute both surface and groundwater.

Description

The former Water Quality Control Branch (WQCB) operated a number of deposition collectors around the province to determine the aeolian deposition rates of various substances to lakes. This deposition program was implemented in 1982 as part of the Wabamun Lake Eutrophication Study. Nine deposition collectors operated between 1982-86. The nine collectors were located at Nakamun East, Nakamun West, Dickson North, Dickson South, Smoke, Iosegun, and three collectors at Lake Wabamun: Wabamun (west of village, Seba (Jackpine Creek) and the Fish and Wildlife compound near Fallis.
