2021 Update - January

Boudreau Pump Station

The Boudreau pump station is located west of the city of Chatham-Kent. It services approximately 340 acres of land in row crop production. Two fields are systematically tiled and drain via two channels. These deliver mostly tile water to the pump station, where it is pumped from the municipal Deary drain to Jeanette’s Creek which discharges into the Thames River.


The soils vary from a Brookston clay to a silt clay loam. Soil P readings are moderate to high (20 to 47 ppm) and the soils have high organic matter (4.7 to 7.6 per cent).

The Lower Thames Valley Conservation Authority (LTVCA) monitored the area under the Great Lakes Agricultural Stewardship Initiative (GLASI) from 2016 to 2019. Water quantity and quality data is available.

Medway Creek

December 2019 Update

Site:

A 100-acre farm in row crops with a tiled field. It has a small barn that is used for wintering 20 head of beef cattle. The test site is at the northeast corner of the property where a single tile delivers water through the small pasture to Medway Creek.

 

Partners:

Upper Thames River Conservation Authority (UTRCA) will be responsible for the site and the Thames River PRC will provide research and weather data support.

 

Research description:

A capsule containing a combination of crushed stone and slag (leftover material from smelting metal) will be inserted into the tile to capture phosphorus (P) from the water that flows out.

 

Water will be sampled before insertion, and the UTRCA will take samples at regular intervals, and especially after major rain events.

Muddy River

Amprey: A New Way to Remove Phosphorus from Agricultural Water Sources

The Ontario Federation of Agriculture (OFA), through the Thames River PRC, is working with the University of Western Ontario (Western) and Muddy River Technologies Inc. to determine how a new technology can remove dissolved phosphorus from a number of water sources.

Muddy River’s  technology is called “Amprey”. 

 

It uses electricity to dissolve particles to form hyper-reactive charged metal ions that attach onto phosphorus and remove it from water. The solid that is formed contains phosphorus and magnesium and can be used as a fertilizer for agriculture rather than being sent to the landfill as waste. The Amprey technology is being tested at a London site with access to Medway Creek.

December 2019 Update

Woodstock

Site:

A 70-acre farm with vegetable, row crops and alfalfa. Crops are rotated based on strips used for strawberries and other green vegetables. In areas other than the vegetable growing area (e.g. hay, corn, soybeans), manure is applied annually. The farm has a municipal drain on the property with three blind inlets.

 

Partners:

GAPS is responsible for installation, sampling and monitoring through Honeyland Ag Services.  The Thames River PRC will provide sample result compilation under the supervision of the Ontario Ministry of Agriculture, Food and Rural Affairs.

 

Research description:

One of the municipal blind inlets drains about 50 acres in an alfalfa field. In this test, an inlet cover is equipped with five Hickenbottom intakes which contain MetaMateria, a sponge that absorbs phosphorus (P), through which water infiltrates.
