HU Editorial Team

Hydrology University content is researched, written and updated by the HU Editorial Team. Here is how we work.

How We Research and Write

Start with published standards

We check product and treatment claims against EPA drinking water regulations and guidance, NSF/ANSI standards, and CDC public health guidance.

Read the research

For health and contaminant topics, we rely on peer-reviewed research and cite the studies we use so you can check them.

Check manufacturer documents

We compare manufacturer specifications with the certifications and test reports manufacturers publish, and we describe those certifications as manufacturer-listed.

Update and correct

We update pages when standards, prices or product details change, and we correct errors when readers point them out.
