(1) SAMPLES FROM WATER SUPPLY WELLS. Responsible parties shall report all water supply well sampling results to the department and to the well owner, and occupant as applicable, within 10 business days after receiving the sampling results. The report to the department shall include the Wisconsin unique well number for drinking water wells, a preliminary analysis of the cause and significance of any contaminant concentrations observed in the samples and an identification of any substances that attain or exceed ch. NR 140 preventive action limits, as well as any other substances observed in the samples for which there are no ch. NR 140 groundwater quality standards. The responsible party shall notify both the remediation and redevelopment project manager and the regional drinking and groundwater specialist or water supply engineer of all water supply well sample results.

Note: The appropriate remediation and redevelopment project manager can be determined for the site in question at http://dnr.wi.gov/topic/Brownfields/documents/rr/county.pdf The appropriate regional drinking and groundwater specialist or water supply engineer can be determined by viewing the staff listing at http://dnr.wi.gov/topic/DrinkingWater/contact.html.

Note: The department will provide information to well owners of the results of sampling in accordance with manual code 4822.1.

(2)SAMPLES FROM OTHER MEDIA. Responsible parties shall report all sampling results other than those for water supply wells, to the department and to the property owner, and occupants as appropriate, of the property from which the samples were collected, including the source property owner if the person conducting the investigation is not the property owner, within 10 business days of receiving the sample results.

(a) The report to the department shall include a preliminary analysis of the cause and significance of any contaminant concentrations observed in the sample, a list of names and addresses of those receiving a sampling notification, and the date of the sampling event and mailing.

(b) The written notification to an affected property owner, and occupant as appropriate, shall include information about how additional information may be obtained, in accordance with s. NR 714.05(5). The department may waive the notification of occupants in limited situations, upon request.

(c) In addition, the notification to the property owners, and occupants as appropriate, shall include all the following information, in a letter or using a form provided by the department:
1. Responsible party name, address, and phone number.

2. Site name and source property address.

3. Department BRRTS number.

4. Department contact person name and phone number.

5. Reason for sampling, which may include routine sampling, and sampling to determine an immediate health concern, including the ingestion, inhalation, and dermal contact pathways.

6. Contaminant type.

7. Sample type, which may include groundwater, soil, sediment, soil vapor, outdoor or ambient air, and indoor air.

8. A map showing the sampling locations, which meets the requirements of s. NR 716.15(4).

9. Collection date, specific contaminant levels per location, and whether the sample results attain or exceed state standards. A data table shall be used when multiple sample results are included.

10. A copy of the results from the laboratory attached to the notification.

Note: Notification of sampling results is intended for those samples taken from a property including results from both routine and long-term monitoring and those of a more immediate health or welfare concern to a property owner, or occupant as appropriate. Examples of sampling to determine the presence of an immediate public health or welfare concern are from potable wells, indoor air, surface soil, and soil vapor beneath an occupied structure. "All sampling results" means the results that show detections of contaminants as well as those that do not show detections.

Note: Assistance in evaluating the impact and meaning of the sample results may be requested of the department project manager or drinking water staff, or from staff with the Division of Public Health, with the Department of Health Services.

Note: The notification to occupants is not intended for situations where there are multiple units or a frequent change in occupancy.

Note: The form on which to provide sample results, "Sample Results Notification," Form 4400-249, can be found at http://dnr.wi.gov/topic/Brownfields/Pubs.html.

(3)The department may approve of a different notification schedule on a case-by-case basis.

Note: In cases where routine monitoring is conducted, and where results are not expected to be of immediate health or welfare concern, the department may consider other schedules, such as quarterly or with the semi-annual status reports to be sufficient.

(4)The responsible party shall take the actions necessary to ensure any new occupants are also informed of the pertinent information required under s. NR 716.14(2) (c).
