Current through June 24, 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.
