(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
