The utilization of RO to achieve emerging contaminant control for indirect potable reuse is commonly accepted in California. Emerging contaminants, also frequently called constituents of emerging concern (CEC) include a wide and diverse spectrum of potential contaminants. They are “potential” contaminants because they are currently unregulated, but may be considered for regulation in the future. They may or may not have public health concerns. Emerging contaminants include constituents such pharmaceuticals, endocrine disrupting compounds (EDCs), hormones, personal care products (PCPs), iodinated contrast media (such as X-ray technology), fire retardants, nanoparticles, and other constituents. Upstream of treatment, source water control is the first step in addressing emerging contaminants. Advanced treatment processes include both reverse osmosis and advanced oxidation processes (AOP). RO/AOP is considered the Best Available Technology (BAT) by CDPH to control organic chemicals, including “emerging contaminants” for indirect potable reuse. RO and AOP are required for injection, and in some cases, may be useful for spreading projects.
