Water Resource Monitoring Programs
Figure 5-1: Wells Used to Monitor Groundwater Levels
For wells within OCWD’s boundaries, groundwater production must be reported at a minimum frequency of every 6 months. Groundwater production volumes from the County of Orange’s wells that supply the Green River Golf Course are now being collected monthly. OCWD also monitors groundwater quality in selected wells in the Santa Ana Canyon Management Area. Table 5-1 lists the wells monitored and the groundwater quality monitoring program each well is part of, which is based on its use (e.g., irrigation, potable). Wells used for irrigation are sampled every year for volatile organic compounds (VOCs) and every three years for general minerals (major cations and anions), 1,4-dioxane, and perchlorate (ClO 4 ). The two wells in Featherly Park used for potable supplies are monitored in accordance with drinking water regulations.
