(4) Ongoing monitoring for lead.

• (a) School officials shall repeat lead monitoring every five years, beginning within:
• (i) Seven years after the effective date of this section for elementary schools;
• (ii) Eight years after the effective date of this section for middle and junior high schools; and
• (iii) Nine years after the effective date of this section for high schools.
• (b) School officials shall use sampling protocols in subsection (2) of this section to collect samples in all schools from:
• (i) No less than twenty-five percent of each type and age of plumbing fixture which is not a "very low lead" plumbing fixture; and
• (ii) No less than ten percent of each type of plumbing fixture which is a "very low lead" plumbing fixture.
• (c) Schools that are Group A public water systems are not required to do ongoing lead monitoring required by (a) of this subsection if the schools meet the lead monitoring requirements in chapter 246-290 WAC.

(1) School officials shall collect water samples and have them tested for copper following the requirements of WAC 246-366A-130 (1) and (2)(b). The same water samples used for lead testing may be used for copper testing. (2) School officials shall test water samples for copper from no less than twenty-five percent of each type and age of plumbing fixture regularly used for drinking or cooking.

• (a) For type of fixture, use at least the three types: Drinking fountains, water coolers and faucets.
• (b) For age of fixture, use at least two groupings: Those manufactured prior to 1999 and those manufactured since January 1, 1999. (3) School officials shall complete water sampling of plumbing fixtures for copper in:
• (a) Elementary schools within two years after the effective date of this section;
• (b) Middle and junior high schools within three years after the effective date of this section; and
• (c) High schools within four years after the effective date of this section. (4) If school officials, with local health officer approval, include lead samples collected after September 1, 2003, toward meeting the initial monitoring requirement for lead, as specified in WAC 246-366A-130, they may wait to monitor those plumbing fixtures for copper until they conduct the next ongoing lead monitoring per WAC 246-366A-130(4). (5) School officials, with local health officer approval, may include samples collected after September 1, 2003, toward meeting monitoring requirements if all plumbing fixtures with copper results above 1.30 milligrams per liter or 1300 parts per billion have been or are being addressed according to subsection (6) of this section, and the samples were:
• (a) From plumbing fixtures regularly used for drinking and cooking; and
• (b) Collected using the sampling protocol specified in WAC 246-366A-130 (2)(b). (6) Corrective actions. For all plumbing fixtures with first draw sample results of copper above 1.30 milligrams per liter or 1300 parts per billion, school officials shall:
• (a) Within five business days of getting sample results, consult with the department to develop a corrective action plan; and
• (b) Implement the corrective action plan. (7) Notification requirements. School officials shall:
• (a) Notify staff, students and parents, and the local health officer within five business days of the school officials receiving copper sampling results above 1.30 milligrams per liter or 1300 parts per billion; and
• (b) Make all results available for review upon request.

The local health officer may require:

• (1) Sampling of drinking water when public health concerns exist about drinking water contaminants other than lead or copper;
• (2) Corrective actions in response to sampling results for other contaminants; and
• (3) School officials to notify school facility staff, students and parents, and the local health officer about test results.
