Pajaro River Nutrients TMDLs

Information

Problem Statement - This TMDL project will address surface water quality impairments in the Pajaro River Basin which are caused by exceedances of water quality criteria for nitrate, unionized ammonia, and associated nutrient-related problems such as excessive orthophosphate, dissolved oxygen imbalances, toxicity, and excess algal biomass.  At this time, these impairments are presumed to impact a range of current or potential designated beneficial uses of surface waters – including aquatic habitat, drinking water supply, groundwater recharge, recreation,  and agricultural supply. This project will identify the water quality impairments and develop a plan for the attainment of water quality objectives and the restoration of designated beneficial uses of surface waters.
