NPDES Effluent Guidelines: A Guide to pH
In the United States, before wastewater can be discharged into a lake or river, it is mandatory to meet the National Pollutant Discharge Elimination System (NPDES) effluent guidelines. These parameters – pH (potential hydrogen), TSS (total suspended solids) and BOD (biological oxygen demand) – can be lowered by controlling algal growth. This blog is the first is a three-part series to ...

What is Ocean Acidification and what Risks does it Pose to Marine Life?
On land, we’re familiar with acid rain — precipitation with acidic components, such as sulfuric or nitric acid. Acid rain can be produced by volcanic events — such as the recent natural disaster in Tonga — as well as by the burning of fossil fuels, manufacturing, and emissions from vehicles and heavy equipment. What many people don’t realize, however, is that these ...
