Adsorption
Bioaccumulation
The gradual accumulation of a substance (or substances) in an organism
Biodegradable

A group of compounds that have been recently detected in water and may pose negative effects to public health or the environment. This includes pharmaceuticals, personal care products, industrial chemicals and endocrine disruptors. Part of the water supply network where potable water (finished water treated at drinking water treatment plants) is distributed to the community through a series of residential, commercial, and industrial service pipes. A form of particulate carbon (media) manufactured to adsorb soluble contaminants such as organics and PFAS. This product has high surface area per unit mass and ability to capture a large variety of contaminants. Compared to PAC, GAC uses large carbon particles and is considered a permanent and robust treatment method for long-term contaminant removal. A well drilled into the ground to access underground water supplies referred to as aquifers. Some of these systems may have treatment systems in place (in the well) to remove fine particles like sand that can clog the well pipe. The time required for a quantity to reduce to half of its initial value in the environment or inside plants, animals, or humans. Water entering the treatment plant or process being discussed (a tank, treatment scenario, watershed, etc.). A water treatment process by which one or more contaminants is removed from water by exchanging with another substance embedded in a manufactured resin. A location where a drinking water treatment plant draws water from source water (usually a reservoir). This point is located at the beginning of the drinking water treatment plant, prior to treatment.
