Stormwater Monitoring Program
Very little is understood about the composition of stormwater in our watershed. The population size of cities around Lake Pend Oreille and the Pend Oreille River are not large enough to trigger regulation of stormwater through the National Pollutant Discharge Elimination System (NPDES) permitting process.
Permitting of stormwater discharges is triggered when a municipal population size reaches 10,000 which requires cities to take certain actions to protect local waterways from stormwater pollution.
Stormwater monitoring can be a helpful tool in determining what exactly is in our stormwater and what types of best management practices should be put into place.
Since stormwater regulation around our watershed is not yet required, there are no robust monitoring efforts taking place to help shed light on the types of pollutants that are common in our stormwater.
LPOW believes that proactive monitoring of stormwater is needed and will produce meaningful information that can be used to mitigate polluted runoff now and into the future.
Laboratory analysis of stormwater samples are very expensive, as much as $300 per test
for pollutants like metals.
