2017 Groundwater Monitoring

CCGC Groundwater Monitoring Requirements for 2017    

Regional Water Board on April 7, 2017 approved the Central Coast Groundwater Coalition (CCGC) Groundwater Management Plan with well monitoring requirements that give existing and new members more time to complete sampling requirements with fewer constituents to be analyzed.

 

The plan also enables CCGC to continue its fourth year of working with growers to comply with the Irrigated Lands Regulatory Program by providing assistance to members in completing Total Nitrogen Applied (TNA) reports, a requirement recently expanded to include all vegetable crops considered “high risk.”  CCGC also plans to be active in negotiating the next General Order, expected to be adopted in 2020.

 

In brief, here are the CCGC member requirements compared to individuals:

  • Domestic Well Monitoring
    • CCGC Members
      • First sample in 2017; second before 2020
      • If previously sampled by CCGC, nitrate (or nitrate + nitrite) analysis only
      • If not previously sampled, complete set of ILRP constituents for first sample (pH, EC, TDS, Alkalinity, Calcium, Magnesium, Potassium, Sodium, Chloride, Sulfate, and Nitrate); the second sample nitrate (or nitrate + nitrite) analysis only
      • All results posted to GeoTracker
      • If there is an exceedance of the Maximum Contaminant Level (MCL) for nitrate in a domestic well sample, the member will be notified by CCGC and required to alert users of the risk associated with using water with high nitrates. The member will need to notify the CCGC of when and how this notification was done in addition to supplying information about any replacement water actions.  CCGC tracks follow-up with members and well users.  If a domestic well was previously identified by CCGC as having a nitrogen exceedance, and users were notified, you must confirm that occupants’ notification is current.
    • Individual Program
      • Two samples in 2017 (Spring-Fall), nitrate (or nitrate + nitrite) plus pH, EC, TDS, Alkalinity, Calcium, Magnesium, Potassium, Sodium, Chloride, Sulfate for both samples
      • All results posted to GeoTracker
      • Regional Board staff tracks follow-up with well users if there is an exceedance of the MCL for a domestic well sample; grower is  responsible for notifying all users about the high nitrates.
  • Primary Irrigation Wells
    • CCGC Members
      • First sample in 2017; second before 2020
      • If previously sampled by CCGC, nitrate (or nitrate + nitrite) analysis only
      • If not previously sampled, complete set of ILRP constituents for first sample (pH, EC, TDS, Alkalinity, Calcium, Magnesium, Potassium, Sodium, Chloride, Sulfate, and Nitrate); the second sample nitrate (or nitrate + nitrite) analysis only
      • All results posted to GeoTracker
    • Individuals
      • Two samples in 2017 (Spring-Fall), nitrate (or nitrate + nitrite) plus pH, EC, TDS, Alkalinity, Calcium, Magnesium, Potassium, Sodium, Chloride, Sulfate for both samples
      • All results posted to GeoTracker
