Laboratory Analytical Methods .................................................................................................... 7 3 1.0 Purpose This Water Quality Assessment and Monitoring Plan provides methods and procedures for the City of Raleigh’s program for monitoring and assessing the quality of water in streams within the corporate limits of Raleigh. Information gained from this program is used to help identify and eliminate sources of pollution, track short-term and long-term trends, and, where possible, evaluate the effectiveness of stormwater management efforts and programs conducted by the City. 2.0 Water Quality Monitoring 2.1 Sampling Methods Stream water samples are fixed-interval grab samples collected at each of 18 monitoring sites. Samples are collected by City staff accessing the monitoring site by wading into the stream from the bank, selecting a target location upstream of the path of wading, typically near the center of the stream channel, immersing monitoring probes in the stream flow for instrument readings, and dipping laboratory-provide sample bottles in the stream flow to collect the water sample. 2.2 Sampling Frequency and Schedule Stream water samples are collected on a quarterly basis, typically during March, June, September, and December. A specific day of each quarter is assigned for sampling (for example, the first Tuesday of the month representing the quarter). Scheduled sampling days sometimes are rescheduled due to inclement weather or high stream flows that create safety concerns. 2.3 Monitoring Parameters Stream water samples are analyzed for the following parameters by a North Carolina-certified laboratory: ammonia nitrogen, calcium, copper, E. coli, magnesium, nitrate + nitrite, total hardness, total Kjeldahl nitrogen, total phosphorous, total suspended solids, turbidity, and zinc. The following additional parameters are measured at each monitoring site using calibrated field instruments: conductivity, dissolved oxygen, pH, and temperature. 4 3.0 Monitoring Sites 3.1 Basis for Locating Monitoring Sites One monitoring site is located within each of 17 major subwatersheds within the corporate limits of Raleigh, and two monitoring sites are located within the Crabtree Creek subwatershed. Monitoring sites typically are located at the downstream-most accessible point of the subwatershed’s stream, intended to represent water quality conditions of that stream and to detect pollutants originating from within that subwatershed. Eighteen monitoring sites are monitored under this plan. 3.2 Subwatersheds and Locations of Monitoring Sites The 18 monitoring sites have been assigned identification numbers. Their locations are described in Table 3-1 and are shown on Figure 3-1. Table 3-1.

This manual details procedures for sample collection, handling, and in situ parameter measurements. The SOPs outlined in this document are intended to serve as technical guidance for field personnel and to ensure consistent, accurate water quality data are collected. All new and existing personnel who collect water quality samples should familiarize themselves with the SOPs prior to sampling. 2.0 PRE-FIELD PREPARATION AND CONSIDERATIONS 2.1 Personnel The Environmental Specialist coordinates quarterly NPDES sampling. For safety, field work is conducted in teams of two or more Stormwater personnel. Quarterly sampling is conducted by two teams of Water Quality Section staff. 2.2 Health and Safety The following items should be discussed with staff before field work to minimize the risk of injury:  Pathogens: Urban waterways may harbor bacteria or other pathogens that are harmful to humans. Caution should be exercised when handling water, sediment, or organic matter from sampling locations. If needed, nitrile gloves can be used for sampling handling and are located in COR vehicles.  Visibility: Staff will be provided with high-visibility safety vests to be worn whenever working near traffic.  Sun and Heat Protection: Staff should use sunscreen and drink water when sampling in hot weather.  Insect Repellant: Staff will be provided with and should use repellant to protect against insect-borne diseases. A thorough check for ticks should be performed after each field effort.  General Safety: Increased flow, turbidity, uneven terrain, debris, and other hazards may exist at sampling sites. Field staff should use caution and always be aware of their surroundings. If conditions such as high flows or inclement weather are present, sampling should be postponed. 2.3 Laboratory Coordination Approximately four weeks before the intended sampling date, the Environmental Specialist will contact the contracted laboratory to notify them of the upcoming field work. Sample bottles, coolers, and appropriate documentation should be requested from the laboratory, including extra bottle sets. Once received, bottles should be counted, verified for accuracy, and pre-labeled with site IDs if necessary. Ensure a plan is in place for subsequent sample drop off at the contracted laboratory that accounts for sample hold times, including travel duration. 2.4 Equipment and Supplies Sampling supplies are inventoried and maintained by the Environmental Specialist. Each sampling group will require an individual set of the materials listed in Table 1. Standard Operating Procedures: NPDES Quarterly Stormwater Monitoring Sampling SOP #SWM2 July 2021 Page 5 of 10 Table 1. Collection Equipment Field Supplies Sampling Bottles Extra Sampling Bottles YSI Pro Plus Meter Spare Meter Batteries Cooler Ice Field Data Form/iPad Waders Supporting Supplies Sunscreen Nitrile Gloves Hand Sanitizer Insect Repellant First Aid Kit, Phone High-Visibility Vests 2.5 Calibration and Standardization Meters used for in situ physicochemical monitoring must be calibrated in a controlled environment (ideally the COR office) and a calibration record form (Appendix A) completed before sampling. The Environmental Specialist should calibrate the meters no more than 24 hours prior to sampling. After each day of field work, a post- calibration check will be conducted to ensure the meters were operating within the accepted range. The following calibration standards must be met:  Dissolved oxygen post-sampling check value must be within +/- 0.5 mg/L of calibrated meter value  Specific conductivity post-sampling check value must be within +/- 10% µS/cm of calibrated meter value  pH post-sampling check value must be within +/- 0.2 SU of calibrated meter value Data from an uncalibrated meter or a meter that failed the post-calibration check should not be used. 3.0 SAMPLING PROCEDURE 3.1 General Water Quality Sampling Overview The following should be considered to ensure consistent and accurate water quality data are collected:  Representativeness. Water quality samples collected in sample bottles as well as in situ measurements should be representative of site conditions (see Section 3.2).  Technique. Proper sampling and preservation techniques should be used to ensure data confidence.  Handling and Custody. Samples should be kept in COR custody until relinquishment to laboratory personnel; all documentation of chain of custody (COC) should be kept on file.  Documentation. Proper identification of collected samples and thorough documentation of site conditions are required. All data should be maintained in an electronic database. 3.2 Site Considerations Sampling should not be conducted in standing or pooled water nor should samples be collected directly downstream of outfalls. Care should be taken not to disturb the sediment in the immediate area of sampling and to ensure sample collection occurs upstream of areas disturbed by Stormwater personnel. 3.3 Sample Collection 3.3.1 Physicochemical Measurements The COR collects the following parameters in the field as in situ measurements:  Water temperature  Specific conductivity  pH  Dissolved oxygen (mg/L and percent saturation) Standard Operating Procedures: NPDES Quarterly Stormwater Monitoring Sampling SOP #SWM2 July 2021 Page 6 of 10 These physicochemical measurements are obtained with handheld multi-parameter meter sondes which have been previously calibrated per Section 2.5. To collect data, sondes should be placed in a representative location within the stream (Section 3.2) and maintained in position until readings stabilize. Measurements should be recorded promptly upon meter stabilization, saved to the device, and recorded on the field data form. 3.3.2 Grab Water Quality Samples All water quality samples should be collected from approximately 6 inches below the surface in a sample bottle provided by the laboratory. For grab sample collection, the sample container should be placed into the stream perpendicular to the water’s surface then inverted so the mouth of the container faces upstream without disturbing the streambed. Sample bottles are filled to the shoulder (or fill line in the case of the E. coli bottle). General guidelines for sample volumes, preservatives, and other considerations are listed in Table 2. Except for the E. coli sample, which is filled directly into the provided, sterile container, all other pre-preserved containers (see Table 2) are filled indirectly. If pre-preserved, do not place these containers within the stream to fill; instead fill pre-preserved containers using an intermediary unpreserved sample container. If a sampling pole or intermediary container is needed, rinse the intermediary container three times prior to collection. Table 2.

All bottles should be placed in coolers on ice. Any samples not meeting temperature, hold time, or preservation requirements or are otherwise not submitted in accordance with the SOP are subject to rejection. 3.4.1 Sample Custody The Environmental Specialist is responsible for completion of the COC form (Appendix B). Proper COC documentation must be filled out immediately after field sampling and kept with the samples. These documents must be signed by the relinquishing party as well as the laboratory upon receipt. Standard Operating Procedures: NPDES Quarterly Stormwater Monitoring Sampling SOP #SWM2 July 2021 Page 7 of 10 3.5 Recordkeeping and Documentation Documentation for the COC (Appendix B) should be completed immediately after sampling; all sample identifiers, dates, and collection times should be recorded. A PDF copy of the COC should be retained for COR records and saved to the s: Drive in the appropriate folder. Data collected using the field data form (Appendix C) are available on ArcGIS Online and should be downloaded after sampling. Data are entered into the sampling database, NPDES_monitoring_site_data, on the s:Drive, located at: \\corfile\EngineeringServices\StormwaterManagement\PROGRAMS\Water Quality_211\Stream monitoring\WATER QUALITY- MONITORING\MONITORING\NPDES\NPDES Monitoring Database In situ data saved to the meters should be extracted and downloaded in the office after each field day. These data should be used to check and validate data from the field data form before entry into the database. Meter data should be stored in the appropriate folder on the s:Drive, located at: \\corfile\EngineeringServices\StormwaterManagement\PROGRAMS\Water Quality_211\Stream monitoring\WATER QUALITY- MONITORING\MONITORING\NPDES\NPDES Monitoring Database\Pro Plus Exported Data Upon receipt of analytical results from the laboratory, data should be entered into the sampling database and a laboratory copy of the data should be stored in the appropriate folder on the s:Drive, located at: \\corfile\EngineeringServices\StormwaterManagement\PROGRAMS\Water Quality_211\Stream monitoring\WATER QUALITY- MONITORING\MONITORING\NPDES\\NPDES Water Quality Lab Reports Standard Operating Procedures: Quarterly Stormwater Monitoring Sampling SOP #SWM2 July 2021 Page 8 of 10 APPENDIX A.
