The samples shall be obtained from the wellhead and properly labeled by the laboratory as such. a. Secondary(Aesthetics): Bicarbonate, carbonate, and hydroxide alkalinity, calcium, iron,magnesium, manganese,p , sodium, and total hardness are due at least once (California Code of Regulations(CCR),Title 22, Section 64449). b. Inorganic Chemicals: Fluoride is due at least once(CCR, Title 22, Section 64432 (m)(1))• C. Nitrate: If the results are over 1/2 of the MCL,then quarterly monitoring for one year will be required.
