Boudreau Pump Station

Site:

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) has monitored this site under the Great Lakes Agricultural Stewardship Initiative (GLASI) since 2016. 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.

Site:

A 100-acre farm situated east of Chatham. Crops are seed corn, soybeans, specialty beans and winter wheat. There is a pig barn on the farm, and crops receive manure from it annually, using a 4R (right time, right place, right source, right rate) nutrient stewardship plan.

 

The 100-acre field is tiled, with a 12-inch outlet on each 25-acre lot that empties into the municipal McKinley drain, and then to the Thames. The soil is a very fine clay loam with phosphorus (P) readings of 50 to 65 ppm. It has a very slow infiltration rate (hydrologic soil group D).

 

Partners:

The Ontario Ministry of Agriculture, Food and Rural Affair is responsible for the model to calculate P recovery, and water flow.

Muddy River

Site:

The City of London has granted access to a test site fully serviced with access to the Medway Creek to test this technology from Muddy River Inc. The site location is unique as it is not influenced by urban runoff. The system is designed to operate year-round.

 

Partners:

Muddy River Inc. is working with researchers at Western University and GAPS to operate and monitor the technology.

 

Research description:

A 20 foot container houses a silt pre-filtration system, a reactor filled with lava rock (source of magnesium) and a post treatment filtration assisted with use of flocculant to capture dissolved phosphorus. The system, equipped to recover the phosphorus and effluent water, can be treated for pH if adjustment is required. Operating parameters will be adjusted to optimize performance.

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.
