  • Total Residual Chlorine
  • Dissolved Oxygen
  • pH
  • Specific Conductance
  • Temperature
  • Settleable Residue 

Initial Application Process

To begin the process, you may request an application form by calling (919) 733-3908 or you may download the application here in either WORD or PDF format.

The following must be returned to this office as part of the application package.

After a complete review of the application package, the auditor assigned to the applicant lab may arrange for the initial on-site inspection of the laboratory's analytical capabilities. The auditor may require evidence of remedial action for any findings cited during the on-site visit prior to proceeding with the application process.

Fees

Once the auditor is satisfied that all requirements have been met, the auditor will send the lab an invoice for the appropriate fee. The fee schedule established in 15A NCAC 2H .0806 is as follows for Field Laboratories.

Maintenance of Certification

During subsequent years, laboratories must obtain acceptable results on PT samples for each parameter on their certificate. The graded results must be received in this office on or before September 30. Each laboratory is also subject to announced or unannounced inspections and must send a written corrective action response to inspection reports within the time allotted.

Renewal of Existing Field Lab Certification

Renewal notification letters and renewal invoices are sent to all laboratories on July 1 for the following year's certification fees. Annual fees must be paid within 60 days of receipt of the invoice. Approximately 30 days before a lab's certification expires, the NC WW/GW LC program will send the lab a renewal letter and new certificate with a certified parameters listing for the following year.
