Summary
Under the Clean Water Act (CWA) the Central Coast Ambient Monitoring Program (CCAMP) conducts monthly monitoring in the Lower Salinas Watershed in order to conduct trend analysis and detect emerging water quality problems. Data is available through the Central Coast Regional Water Quality Control Board (CCRWQCB) website. All monitoring is conducted by Central Coast Water Quality Preservation, Inc (Preservation, Inc.) under authority from the Ag Order (Order no. R3-2012-0011).
Status of Nitrate
The overall target TMDL for Nitrate is 10 mg/L for all receiving waterbodies. During the dry season (May 1st - October 31st) Nitrate should not be over 1.4 - 6.4 mg/L in impaired receiving waters for specific streams. During the wet season nitrate should not exceed 8 mg/L for impaired, receiving streams. [1]

Status of Un-ionized Ammonia
The target TMDL for un-ionized ammonia is 0.025 mg/L.[1] The majority of the water bodies in the Lower Salinas Valley have an un-ionized concentration mean bellow 0.025 mg/L. CCAMP has identified a monotonic decreasing trend of Ammonia levels at Tembladero Slough at Haro Road.

Status of Orthophosphate
The target TMDL concentration for orthophosphate is 0.3 mg/L during the wet season (November 1st - April 30th). The dry season target (May 1st - October 31st) depends on the specific waterbody, but target threshold ranges from 0.7 mg/L to 0.13 mg/L. [1] CCAMP has identified a monotonic decreasing trend of Orthophosphate levels at Tembladero Slough at Haro Road.
