Sampling, analysis, and laboratory requirements

Sampling, analysis, and laboratory requirements. Sampling, analysis, and laboratory requirements. This section applies to all sampling required under chs. NR 507 and 508 . The owner or operator shall obtain and analyze samples according to the approved sampling plan and the following requirements: (1) Field measurements. The owner or operator shall observe and record physical measurements in the field at the time of sampling each groundwater monitoring well or leachate well, including all of the following: (a) Water level elevation. Water level elevations shall be measured prior to purging the well for sampling and recorded to the nearest 0.01 foot. The elevation shall be corrected to national geodetic survey datum. The measuring point shall be the top of the well casing and shall be identified on the well itself if the top of the casing is not level. (b) Physical appearance. The physical appearance of the sample, including color, odor and turbidity, shall be recorded at the time of sampling. (c) Chemical measurements. Field specific conductance at 25 ° C and field pH shall be measured immediately following purging of each well. If the well can be purged dry, these measurements shall be taken when the sample is collected. Field specific conductance readings shall be corrected to 25 ° C if the meter used does not automatically correct for temperature. (2) Sample collection. Samples shall be collected in accordance with the approved sampling plan under s. NR 507.16 . (3) Analytical parameters. The analytical parameters which shall be used for environmental monitoring under this chapter are listed in ch. NR 507 Appendices I through IV. The department may require analysis of additional parameters depending on the characteristics of the waste, the raw process materials used, or the provisions of ch. NR 140 . (4) Analytical methods. Groundwater, lysimeter, and leachate samples shall be handled and analyzed in accordance with ch. NR 149 or other suitable analytical method identified by the department in writing. Screening methods may not be used unless approved in writing by the department. Water supply samples shall be handled in accordance with s. NR 507.20 . (5) Laboratory requirements. All chemical analyses shall be conducted by a laboratory certified under s. 299.11 , Stats., and ch. NR 149 . The limit of detection and the limit of quantitation shall be determined according to s. NR 149.48 (2) and (3) . The analytical laboratory shall meet the requirements of the analytical method and ch. NR 149 . Section NR 140.16 (4) applies to analytical results that do not meet the requirements of this subsection. (6) Data reporting requirements. The owner or operator shall report laboratory quality control indicators in accordance with s. NR 507.26 (3) (b) . (7) Other/test requirements. The following tests shall be performed using department guidance, or if no guidance is available, current industry standards or procedures: (a) Physical tests of soil. (b) Physical tests of waste. (c) Chemical tests of waste. (d) Air quality tests. (e) Gas tests. (f) Field pH tests. (g) Field conductivity tests. (h) Product quality testing. (i) Nutrient testing of soils and waste. (j) Turbidity tests. (k) Water elevation. (L) Temperature. (m) Leachate liner compatibility testing.
