Is testing required for my new well?

NCEHD only requires testing to be done when the well will be hooked up to a new residence. In those cases, a well yield test and a raw water certification are required. A well yield test is a four-hour pump test to determine if the well can produce at least 3.0 gallons per minute sustained production rate. The well ordinance will grant approval for the Certificate of Occupancy for well production as low as 1.5 gallons per minute with a required minimum 1000 gallon holding tank. A raw water certification is a bacteriological test performed by a California State laboratory that determines if there are any coliform bacteria present in the water. The sample is taken by an NCEHD Specialist and requires an application and fee.
