A novel biological oxidation filtration treatment process was evaluated for removal of ammonia from a California groundwater source. In addition to ammonia, this groundwater had other contaminants such as iron, manganese, methane, hydrogen sulfide odor, color, high organic carbon, etc. As such, more conventional treatment processes such as breakpoint chlorination were deemed infeasible, and biological treatment was the preferred treatment alternative.
Turbidity, a measure of the cloudiness or haziness of a fluid, was originally intended as a qualitative measure of the aesthetics of drinking water. It is not a measure of actual particles in the water; it measures how much those particles affect light being transmitted through the water, or how that light reflects off particles in the water. Today’s turbidity designs and methods have been regimented in an attempt to bring quantitative consistency to the measurement for both aesthetic and pathogenic qualities of drinking water.
Ratepayers are debating the merits of a proposal for a new desalination plant in Orange County, CA.
September of 2017 was the busiest month of hurricane activity on record, according to the Weather Channel.
Turbidity measurement is both a nebulous, oft-misunderstood concept and the master link in a chain of events affecting U.S. EPA drinking water compliance. It can influence, or be influenced by, almost every other link in a water treatment process. Here is a quick overview of turbidity’s relationship to drinking water compliance standards and some tips for keeping a water treatment process in balance.

California is home to some of the world’s most creative minds, top universities, productive farmland, groundbreaking industries — and one of the most epic droughts. The state has endured five years of drained reservoirs and groundwater reserves tapped so aggressively that the land subsidence caused by pumping has been literally seen from space. This indicates in no uncertain terms that it’s time to get all hands on deck. Private companies, universities, irrigation and drainage districts, municipalities — it’s time to pull together into public-private partnerships to address water challenges that face California and so many other regions of the world.

Aside from the movie Titanic, I don’t have much knowledge about icebergs. However, you hear the phrase all the time - the majority of every iceberg is under water, out of sight for most people. It’s a common fact that 90% of an iceberg’s mass is below the surface, and this fact can be related to most things in life. Ninety percent of the people you meet and interact with everyday are agreeable/pleasant to be around, and some would argue that 90% of communication is body language and non-verbal.
Data analysis around pipe condition, inflow & infiltration (I&I), and overflows can build a case for the approval of infrastructure funding in budget planning.
The phrase “Necessity is the mother of invention” has been definitively traced back to early 16th century England, and even attributed to Plato in the Latin form, “Mater artium necessitas.” In today’s world of water, necessity is also becoming a major factor in rising interest regarding potable water reuse. This is especially true in areas where changes in climate or usage demands have stressed traditional sources of supply, as evidenced by increasing numbers of applications worldwide. For those who work in a water-stressed environment, this article can provide added perspective on specific points of opportunity — and points of caution.
Economist Harold Pollack's New York Times article suggesting priorities for your philanthropic work was a fun read for those of us who would love to imagine what we would do with $131 billion.
