Wet Event samples were collected during storms that were forecast to have 0.25” of rain or more. Dry Event samples were collected following 7 days of dry weather (<0.1" rainfall).
Each monitoring station is given a code according to the type and location of the station. The letters before the dash indicate whether a site is a mass emission station (ME), major outfall station (MO), or alternate site used for dry weather monitoring when the major outfall station is dry (DRY). The remaining letters indicate location. Mass Emission stations are located on the mainstem of the receiving water in each of the three major watersheds: Santa Clara River (ME-SCR), Calleguas Creek (ME-CC), and Ventura River (ME-VR2). Major Outfall stations are located on representative outfalls for each city: Camarillo (MO-CAM), Fillmore (MO-FIL), Moorpark (MO-MPK), Ojai (MO-OJA), Oxnard (MO-OXN), Port Hueneme (MO-HUE), Santa Paula (MO-SPA), Simi Valley (MO-SIM), Thousand Oaks (MO-THO), Ventura (MO-VEN) and unincorporated county (MO-MEI in Meiners Oaks and UNI# for dry weather).
Indicates when the sample was taken, e.g. “2010/11-2” means the second monitored storm in the 2010-2011 wet season (October 1 – April 15). “….-DRY” events occur during the dry season (April 16 – September 30) of the year referenced.
The general category to which a constituent belongs.
The chemical or substance of interest.
“Total” and “n/a” refer to samples that were analyzed without filtration or are insoluble. Dissolved samples were filtered prior to analysis. For example, the fraction for metals can be total or dissolved; however the dissolved component of metals is considered more bioavailable and thus more likely to affect aquatic life than the total quantity of the metal present.
The start date can not be sooner than the end date.
