FAQs

Question: Why not simply look out the window to see when it is raining?
Answer: All rainstorms are not created equal. The definition of a qualifying storm varies significantly from State to State regarding the necessary intensity of the storm, as well as the precipitation history of the preceding days. The email alert you will get has been tailored to the requirements of your State, and the precipitation history for your specific location.
Question: Who Should Use StormWaterSamplingAlert.com?
Answer: Anyone who is responsible for complying with the monitoring requirements of an NPDES or State Industrial Stormwater General Permit, for one or multiple locations, either as the permittee or as a contracted sampling technician.
Question: What if there is no qualifying storm in a monitoring period?
Answer: StormWaterSamplingAlert.com will help you document that no storms during the period met the requirements, either in terms of intensity, or time since the last significant rainfall. This could be of benefit in the event of a dispute between the regulatory agency and permittee, or between the permittee and a contracted sampling technician.
