The county health officer may, upon reasonable cause to believe that an abandoned well or other well is causing a nuisance by polluting or contaminating groundwater, or constitutes a safety hazard, investigate the situation to determine whether such a nuisance does in fact exist. He shall have the power, when in the performance of his duty and upon first presenting his credentials and identifying himself as an employee of the county health department to the person apparently in control of the premises, if available, to enter upon any such premises between the hours of 8:00 a.m. and 6:00 p.m. to discover or inspect any thing or condition which appears to indicate such a nuisance in accord with right-of-entry provisions set forth in CVMC 1.16.010. He may examine such premises, things or conditions, take such samples and make such tests as needed, and take any other steps reasonably necessary for the proper investigation and determination of whether such a nuisance exists. (Ord. 1547 § 1, 1974; prior code § 35.707).
