Bottles

Detailed Description

For each storm event, automated samplers collect 24 water samples at defined time intervals throughout the runoff period. The first samples usually have less sediment (shown on the left) because this runoff comes directly from impervious surfaces such as streets and parking lots. Samples near the peak flow (center bottles) usually have the highest sediment and bacteria concentrations.
