Pathogen means an organism that is capable of producing an infection or disease in a susceptible host.
Disinfection means a process which inactivates pathogenic organisms in water by chemical oxidants or equivalent agents.
Diatomaceous earth filtration means a process resulting in substantial particulate removal in which a precoat cake of diatomaceous earth filter media is deposited on a support membrane (septum), and while the water is filtered by passing through the cake on the septum, additional filter media known as body feed is continuously added to the feed water to maintain the permeability of the filter cake.

Invasive plant species means species of plants not historically found in California that spread outside cultivated areas and can damage environmental or economic resources. Invasive species may be regulated by county agricultural agencies as noxious species. Lists of invasive plants are maintained at the California Invasive Plant Inventory and USDA invasive and noxious weeds database.
COVID-19 symptoms means fever of 100.4 degrees Fahrenheit or higher, chills, cough, shortness of breath or difficulty breathing, fatigue, muscle or body aches, headache, new loss of taste or smell, sore throat, congestion or runny nose, nausea or vomiting, or diarrhea, unless a licensed health care professional determines the person’s symptoms were caused by a known condition other than COVID-19.
Acute toxicity means concurrent and delayed adverse effects that result from an acute exposure and occur within any short observation period, which begins when the exposure begins, may extend beyond the exposure period, and usually does not constitute a substantial portion of the life span of the organism.
Autism spectrum disorders means any of the pervasive developmental disorders as defined by the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, published by the American Psychiatric Association, including autistic disorder, Asperger's disorder and pervasive developmental disorder not otherwise specified.[PL 2011, c. 420, Pt.

Fluoroscopic imaging assembly means a subsystem in which X-ray photons produce a visual image. It includes the image receptor(s) such as the image intensifier and spot-film device, electrical interlocks, if any, and structural material providing linkage between the image receptor and diagnostic source assembly.
Corrosion inhibitor means a substance capable of reducing the corrosivity of water toward metal plumbing materials, especially lead and copper, by forming a protective film on the interior surface of those materials.
Opioid means a drug that produces an agonist effect on opioid receptors and is indicated or used for the treatment of pain.
Biological agent shall mean any pathogenic (disease producing) micro-organism(s) and/or biologically produced toxin(s) (including genetically modified organisms and chemically synthesized toxins) which cause illness and/or death in humans, animals or plants.
