Field Procedure
Step 1.
Go to store and gather materials for sampling. Go to ALS Laboratories on Lougheed Hwy in Burnaby, BC and obtain a manual water pump and filters that are heat resistant (they will have to go in the oven later on)
Step 2.
Review map and select representative rivers. Make sure that the rivers or creeks cross a large urban area. The following 3 rivers were selected that cross urban developments:
Step 3.
Select sampling point locations for each river. Two sampling point locations were selected for each river, one upstream of the urban area, and one downstream form the urban area, close to Burrard Inlet. The locations were as follows:
Step 4.
Go to each sampling point. Label each plastic container using the painters tape and a permanent marker, and mark river, sample number and if they are upstream or downstream. In addition we noted the time of the day and date of sampling.
Step 5.
Take water sample either by hand or by using the sampling pole and duct tape around the container. The plastic container was held with the opening against the water and without disturbing the sediment at the bottom of the river.
Step 6.
Cover the container with the lid to avoid rain water to get into the container. Place sample in thermos bag to stay at the same temperature as it was when it was sampled.
Step 7.
Store samples for at least 24 hours to let suspended solids settle. This allowed us to see if any suspended solids accumulated at the bottom of the plastic container. Containers were kept with lids locked on them.

Step 2.
Review map and select representative rivers. Make sure that the rivers or creeks cross a large urban area. The following 3 rivers were selected that cross urban developments:
- Mosquito Creek, in North Vancouver, BC.
- Capilano River, in West Vancouver,BC
- Brothers Creek, in West Vancouver, BC
Step 3.
Select sampling point locations for each river. Two sampling point locations were selected for each river, one upstream of the urban area, and one downstream form the urban area, close to Burrard Inlet. The locations were as follows:
- For Mosquito Creek: the upstream point was located at the bridge crossing at Montroyal Boulevard, and the downstream point at 2nd Street West and Bewike avenue.
- For Capilano River: the upstream point was located at the Capilano River Salmon Hatcery, and the downstream point at Taylor way and Bridge Road.
- For Brothers Creek: the upstream point was located before British Properties at Millstream Road, and the downstream point close to Keith Road and Keith Place.
