Linking BMPs to

Pollutant Sources

After impairments are understood, pollutant causes and sources known, pollutant loads estimated, critical areas identified…. it’s time to select the treatment measures – BMPs – that will achieve your goals.

Linking BMPs to Sources

• Match BMP to pollutant(s)• Match BMP to source(s)• Consider pollutant transport/delivery• Evaluate load reduction capability• Cost• Acceptability/practicality

Consider pollutant transport/delivery

BMP interventions in NPS pathways:• Availability/pollutant prevention (e.g., NMP)• Detachment (e.g., conservation tillage)• Transport (e.g., WASCOB)• Delivery (e.g., filter strip, riparian buffer)

Evaluate load reduction capability• Stormwater/Urban (BMP Effectiveness database; Menu

of BMPs)• Agriculture (Ag Management Measure document)• Forestry (Forestry Management Measures document)• Mining (Development document for proposed Effluent

Acceptability/practicality

• Look at what’s worked and what hasn’t• Consider costs/benefits• Property ownership/site access • Look for added benefits• Use a combination of techniques
