Current through August 26, 2024

The owner or operator shall submit a sampling plan for all monitoring devices at the facility for approval as part of the feasibility report. The sampling plan shall be implemented as approved in writing by the department. The sampling plan shall follow procedures and methodologies specified by the department and shall comply with the requirements in s. NR 140.16.

Note: The department developed the Groundwater Sampling Desk Reference, PUBL-DG-037 96, document sales stock no. 1728D, September 1996, and Groundwater Sampling Field Manual, PUBL-DG-038 96, document sales stock no. 1729D, September 1996. These publications are available at http://dnr.wi.gov/org/water/dwg/gw/pubdnld.htm. They may also be obtained from the department of administration, document sales & distribution, 4622 University Avenue, Madison, WI 53705-2156, (800) 362-7253, http://docsales.wi.gov. The reference and manual are available for inspection at the offices of the department of natural resources, the legislative reference bureau and the secretary of state.

(1) CONTENTS OF SAMPLING PLAN. At a minimum, the following information shall be included in the sampling plan:

(a) An 8 1/2 by 11 inch site map showing locations of all sample points and devices. An 11 by 17 inch site map may be included if clarity is compromised using the 8 1/2 by 11 inch size. Different symbols shall be used to differentiate types of monitoring devices such as groundwater monitoring wells, collection lysimeters and gas monitoring wells. Each sample point shall be labeled.

(b) A sample schedule, including all of the following:
1. The months that each sample point is to be sampled.

2. The sampling period, as designated by the department.

3. The list of parameters that are to be analyzed for in the sample from each monitoring device during each month that sampling occurs.

(c) Procedures for field measurements, including all of the following:
1. The order in which wells should be sampled if the groundwater has been impacted by regulated or other activities.

2. The procedures and type of equipment used to measure water level elevations.

3. The procedures and type of equipment used to measure temperature, pH, conductivity and procedures to determine turbidity, odor and color.

(d) Procedures for purging wells, including all of the following:
1. Procedures to purge wells prior to collecting samples.

2. Procedures for determining the volume of water to be removed from each well.

3. The type of equipment used to purge wells.

4. The rate of flow while purging, when applicable.

5. Procedures to clean purging equipment between wells.

6. The amount of time required between purging and sampling.

(e) Procedures for obtaining samples from wells, including all of the following:
1. Procedures and type of equipment used to retrieve samples.

2. Volume of sample required for analysis.

3. Procedures and type of equipment to filter samples, including when to filter and when not to filter samples, if applicable.

4. The rate of flow when sampling, when applicable.

5. Procedures and type of equipment to physically and chemically preserve samples.

6. Procedures to clean sampling equipment following sampling of one well and prior to sampling the next well.

(f) Procedures for establishing field quality assurance and quality control, including all of the following:
1. Field blank, duplicate sample and trip blank procedures.

2. The frequency at which the field blanks, duplicate samples and trip blanks will be collected or processed.

(g) Special procedures to sample water supply wells.

(h) Special procedures to sample leachate headwells and other devices.

(i) Chain of custody procedures, including persons responsible for sampling and methods for transporting samples to the laboratory.

(2) AVAILABILITY OF SAMPLING PLAN . A copy of the approved sampling plan shall be kept at the facility or at the office of the facility owner and a copy shall be provided to the sampling personnel for use during sampling. The approved sampling plan shall be followed unless the department is notified of and concurs with modifications. The owner or operator shall submit documentation of the approved changes to the department within 90 days. The owner or operator shall retain field records of all monitoring activities throughout the long-term care period.
