Water Quality Parameters

What We Test – Physical, Chemical & Biological

Lake Pend Oreille | Pend Oreille River

The goal of LPOW’s citizen-based Water Quality Monitoring Program (WQMP) is to produce reliable, scientifically-credible data that lends insight into the water quality of Lake Pend Oreille and its affiliated waterways. The high quality data collected by Lake Pend Oreille WATERKEEPER® can be referenced by regulatory agencies, such as the Idaho Department of Environmental Quality (IDEQ), when making decisions about the “health status” and management of Lake Pend Oreille and the Pend Oreille River. To learn more about IDEQ’s water quality standards for the nearshore waters of Lake Pend Oreille, check out the link attached to this page.

Regular monitoring will establish baseline levels for a range of parameters that are indicators of water quality. Continued sampling on a seasonal basis will allow LPOW to detect changes and potential threats to water quality in our lake and river.

Citizen-based Water Quality Monitoring

Due to the extensive nature of LPOW’s jurisdiction and the need to monitor multiple locations, LPOW relies on the generosity of volunteers to assist in monitoring efforts. Volunteers collaborate with LPOW staff to collect water samples on a monthly basis. Volunteers are provided with the necessary equipment and supplies and are trained to properly collect water samples, perform certain analyses in the field, and store other samples for subsequent laboratory analyses. Volunteers agree to arrange for the delivery of samples to LPOW or to SVL Analytical, the full-service environmental laboratory in Coeur d’Alene.

Laboratory analysis of water samples are very expensive totalling about $1,000 per station per field season. Your donation helps cover the costs of collecting & analyzing water samples.
