Stormwater Monitoring - Considerations for Selecting Sampling Technique

Selecting the optimum stormwater sampling approach is a key element to managing costs for stormwater compliance monitoring.

[read more about three basic approaches to collecting stormwater samples]

Selecting the appropriate option for a given discharger requires consideration of all the outfalls that need to be sampled. For example, some outfalls may not be conducive for installing automated sampling equipment, and might require a different technique. Therefore, if a facility has four outfalls to sample and one can not be effectively sampled with automated equipment, staff may need to be trained to collect samples at that outfall anyway, and therefore it may not make much sense to install automated equipment at the other outfalls, unless other factors prevail.

The bottom line is that selecting a reliable and cost effective sampling method is dependant on a number of factors, including:

  • Frequency of monitoring
  • Types of parameters to be tested for
  • Physical layout and constraints of the outfalls
  • Safety considerations
  • Availability of on-site staff
  • Availability of contract sampling vendors
  • Availability of equipment
