In Reply Refer To: September 27, 1990 WGS-Mail Stop 412 OFFICE OF WATER QUALITY TECHNICAL MEMORANDUM NO. 90.13 Subject: PROGRAMS AND PLANS--National Water-Quality Networks: Fiscal Year 1991--October 1, 1990 to September 30, 1991 This memorandum contains an outline of Program status and protocol for operation of the National Stream Quality Accounting Network (NASQAN) and the Hydrologic Benchmark Network (HBMN) for fiscal year (FY) 1991. All personnel responsible for collecting NASQAN or HBMN samples should read this memorandum. Network data collection can be significantly enhanced when personnel responsible for field data collection are informed of changes in sample collection and processing procedures. NETWORK OPERATIONS, FY 1991 Operation during FY 1991 of both NASQAN and HBMN will have few changes from the FY 1990 protocol. There are no changes in the stations in the HBMN. Three stations were added to the NASQAN program and four stations were dropped. States affected by these changes are Alabama, Connecticut, Michigan, Oregon, South Dakota, and Wyoming. These changes are indicated in Appendix A. Sampling frequencies at all stations remain unchanged. Following are some operational changes and notes for FY 1991: 1. Collection of Samples for Bacteriology Analysis of the parallel fecal streptococcal bacteria data sets collected by several Districts during FY 1990 using both 0.45 and 0.7 um pore size filters showed that the data are comparable. For FY 1991, the revised fecal strep method described in TWRI, Book 5, Ch A4, p. 47 (Britton and Greeson, 1989) which specifies a 0.45 um pore size filter is to be used for all National Network stations. The filter pore size that should be used for fecal coliform samples is 0.7 um. Fecal coliform data are to be stored under parameter code 31625 and fecal strep data are to be stored under code 31673. Additionally, samples collected for bacteriology at National Network stations should be obtained as a surface grab from the centroid of flow in a sterile container. Depth and width integrated sampling for bacteriology has not been recommended for National Network stations. To date, a recommendation has not been made to use depth and width integrated sampling for bacteriology samples in order to maintain consistency. The principal network objective of time trend detection requires a consistent data collection effort. Consistent temporal and spatial data collection produces data applicable to the objective and comparable across regions and the country. Therefore, changes in network sampling approach should be introduced consistently across the network with care. Questions regarding changes in approach should be directed to the National Network Coordinator prior to implementation. (NOTE: Any District that has been using depth and width integrated sterile bacteria sampling for 4 years or more may continue to do so. Those Districts should notify the Network Coordinator so their collection procedures can be documented.) 2. Shipping Nutrient Samples Bottles for nutrient analyses (RC and FC -- brown bottles) are to be shipped to the National Water Quality Laboratory in a separate cooler from other sample bottles. No other sample types are to be placed in the cooler. The cooler should be lined with a plastic bag that is then tied or sealed closed at the top to prevent leakage. The nutrient samples are to be shipped to the lab as soon as possible after sample collection, preferably from the field, and marked priority mail. The Analytical Services Request Form for schedule 86 should be sealed in a zip-lock bag and included with the nutrient sample bottles. A postcard requesting the arrival date and temperature of the sample can be placed in the cooler. Lab personnel will fill out the information and return the postcard to the District. This will enable you to determine how long it takes samples to arrive at the lab and will document whether they have been properly chilled. The reasons for handling nutrient bottles separately from other bottles are: 1) to prevent contamination of other sample types by the mercuric chloride preservative used in the nutrient samples; and 2) to help decrease the turn-around time for the analyses. Small coolers can be used for one or two sets of nutrient bottles. Be sure that the cooler used is large enough to hold a sufficient amount of ice to keep the sample bottles chilled to 4 degrees Celsius until they reach the lab. Coolers used for nutrient samples should be dedicated for nutrient samples only to prevent possible subsequent contamination of other sample types. 3. Storing Sample Purpose Code A value for parameter code 71999 (Sample Purpose Code) is to be stored with all NASQAN and HBMN samples. The following values are to be used: 20.00 = NASQAN 30.00 = Benchmark Use of this code will allow identification and retrieval of Network samples for data analysis. 4. Preservative Order Per Office of Water Quality Technical Memorandum 90.01, preservatives are to be added in the following order: Nitric acid to the FA bottle Potassium dichromate to the FAM bottle Mercuric chloride to the RC and FC bottles Be sure each bottle is capped and stored before going to the next preservative. Handle ampuoles carefully and dispose of them according to the method outlined in memo 90.01. This will help prevent sample contamination. 5. Bottle Types Following is a list of bottle types and the analyses that are done from each. Individuals processing Network samples should be aware of this information as means of preventing sample contamination.

Collection of Representative Samples As in past years, the Office of Water Quality and the NASQAN/Benchmark staff remind all field personnel that the collection of a representative sample is of utmost importance. Procedures for the collection of a representative sample are well documented. As part of this effort, cross-section surveys (depth and width) of water temperature, pH, specific conductance, dissolved oxygen, and suspended sediment have been required activities at each site in the two networks. Over a period of years the data base of such data should include observations for various seasons and surface water discharges. Cross-section surveys should include a discharge measurement so that each measured constituent can be associated with a weighted discharge value. The results of cross-section surveys should be stored in the WATSTORE/NWIS Water-Quality File. When entering such data, be sure to enter the cross section location - WATSTORE code 00009, CROSS-SECTION LOCATION, FEET FROM LEFT BANK, LOOKING DOWNSTREAM. Periods for Sample Collection The table below indicates the time periods for sample collection for stations sampled quarterly (four times per year) and bimonthly (six times per year). Sample collection frequencies for each site remain the same in FY 1991 as they were in FY 1990. QUARTERLY STATIONS BIMONTHLY STATIONS first sample OCTOBER-NOVEMBER-DECEMBER OCTOBER- NOVEMBER second sample JANUARY-FEBRUARY-MARCH DECEMBER- JANUARY third sample APRIL-MAY-JUNE FEBRUARY- MARCH fourth sample JULY-AUGUST-SEPTEMBER APRIL-MAY fifth sample ------------------------- JUNE-JULY sixth sample ------------------------- AUGUST- SEPTEMBER Use of ICP Use of the inductively-coupled plasma (ICP) procedure for the analysis of selected dissolved common and trace inorganic constituents will continue to be utilized to decrease analytical costs. The ICP procedure is not to be used whenever the specific conductance is greater than 2,000 uS/cm because the detection limits become greater. Schedule 177 will be used in lieu of schedule 176 whenever the specific conductance is greater than 2,000 uS/cm. Based upon historical specific conductance data for each NASQAN and HBMN Station, the percentage of samples with specific conductance values equal to or greater than 2,000 uS/cm was computed and is given in Appendix A under the right-hand heading "PROBABILITY (%) THAT SPECIFIC CONDUCTANCE WILL BE EQUAL TO OR GREATER THAN 2,000 US/CM." These probabilities indicate the expected frequency of use schedule 177 will get at each site over a long period of time. Determination of specifically which schedule to request for a sample is based on the specific conductance value measured at the time of sampling. Only schedule 176 is authorized for stations with zero probability of the specific conductance exceeding 2,000 uS/cm. Because of the uncertainty involved in predicting the number of samples during FY 1990 that will exceed 2,000 uS/cm, both schedule 176 and 177 are authorized for four uses at NASQAN and HBMN stations where the value given in the right-hand column of Appendix A is greater than zero. The actual number of usages authorized between schedules 176 and 177 is however four, not eight, for both HBMN and NASQAN. District Water-Quality Specialists have the authority and responsibility to request schedules 176 versus schedule 177. Because use of schedule 176 versus 177 is dependent solely upon the specific conductance of the sample, District Water-Quality Specialists should ensure that all field personnel are aware that a field specific conductance measurement is absolutely necessary whenever schedule 176 or 177 is to be utilized. Unique Numbers Districts are reminded that all samples (excluding suspended- sediment samples which are analyzed in District sediment laboratories for particle size and concentration) are to be sent to the U.S. Geological Survey National Water-Quality Laboratory in Arvada, CO, with appropriate National Laboratory unique numbers. The necessary computer program documentation to retrieve unique numbers is given in Quality of Water Branch Technical Memorandum 79.15. Unique numbers can also be obtained by station number through the SPN system on DCOLKA. New unique numbers are established at the beginning of the each water year and are to be used until September 30 of each water year. Personnel collecting NASQAN or HBMN samples should keep a current listing of the unique numbers in their field folder. Any National-Networks sample processed by the National Laboratory without a unique number will result in the analytical costs being billed to the District default account instead of the appropriate National-Networks account. Correcting such billing errors after they occur requires a memorandum to the Coordinator, National Water-Quality Networks. Analytical Services Request Form Although the unique number, date, and time are all that are required on the Analytical Services Request Form, additional information such as station name, special sampling conditions, National-Networks program (NASQAN, Benchmark), etc., are helpful to the National Laboratory personnel and District personnel processing the analytical results. All information coded in the comments section of the Analytical Services Request Form is stored in the Water-Quality File. Uniform Data-Collection Program Districts are reminded of the importance to ensure that all NASQAN and HBMN samples be analyzed for the same measurements as specified later in this memorandum. In particular, all field measurements specified have to be done for every sample. Analytical Schedules There are no changes to any of the analytical schedules used in the NASQAN and Benchmark networks in FY 1991. Note that the bottle requirements for schedule 1703 (radiochemicals) were changed during FY 1990. NASQAN DATA COLLECTION PROGRAM NASQAN stations to be operated during the period October 1, 1990 through September 30, 1991 are listed in Appendix A. The network will have 410 stations. There will be one NASQAN station sampled monthly, 244 NASQAN stations sampled bimonthly, and 165 NASQAN stations sampled quarterly. NASQAN Sampling Schedule for FY 1991 Please notify the Office of Water Quality if the District responsible for collection of samples for any NASQAN station has changed recently and is therefore incorrectly listed in Appendix A. NASQAN Sampling Schedule (Quarterly Stations) 4 per year - Field measurements: Instantaneous discharge (WATSTORE Code 00061) Specific Conductance (WATSTORE Code 00095) Water temperature, oC (WATSTORE Code 000010) Barometric pressure (WATSTORE Code 00025) pH (WATSTORE Code 00400) Carbonate, water, dissolved, mg/L (WATSTORE Code 00452) Bicarbonate, water, dissolved, mg/L (WATSTORE Code 00453) Alkalinity, water, dissolved, as CaCO3, mg/L (WATSTORE Code 39086) Hydroxide, water, dissolved, mg/L (WATSTORE Code 71834) Dissolved oxygen (WATSTORE 00300) Fecal coliform bacteria, 0.7 um (WATSTORE Code 31625) Fecal streptococcal bacteria, 0.45 um (WATSTORE Code 31673) 4 per year - Suspended sediment: Concentration (WATSTORE Code 80154) Percent finer than 0.062 mm, sieve diameter (WATSTORE Code 70331) 4 per year - Nutrients, lab schedule 86 4 per year - Physical properties, common and trace dissolved inorganic constituents: lab schedule 176 (specific conductance <2,000 uS/cm) or lab schedule 177 (specific conductance >2,000 uS/cm) Cross-section surveys (depth and width) of temperature, pH, specific conductance, dissolved oxygen, and suspended-sediment concentration as needed to document cross-section homogeneity. NASQAN Sampling Schedule (Bimonthly Stations) 6 per year - Field measurements (same as quarterly) 6 per year - Suspended sediment (same as quarterly) 6 per year - Nutrients, lab schedule 86 2 per year - Physical properties and common dissolved inorganic constituents: lab schedule 1904 (not used when schedule 176 or 177 is used) 4 per year - Physical properties, and common and trace dissolved inorganic constituents: lab schedule 176 or 177 Cross-section surveys (depth and width) of temperature, pH, specific conductance, dissolved oxygen, and suspended-sediment concentration as needed to document cross-section homogeneity. NASQAN Radiochemical Subnetwork NASQAN Radiochemical Subnetwork Stations for FY 1991 are the same as those in FY 1990. Stations are indicated in Appendix A by listing a "2" under the heading "SCHEDULE 1703 RADIOCHEM". There are 46 stations. 2 per year - Radiochemicals, lab schedule 1703 HYDROLOGIC BENCHMARK DATA COLLECTION PROGRAM Hydrologic Benchmark Network stations to be operated in FY 1991 are unchanged from FY 1990, and are listed in Appendix A. At 3 HBMN stations, only surface water discharge data are to be collected: these are also given in Appendix A. Of the 55 stations to be sampled for water quality during FY 1991 forty- three (43) HBMN stations will be sampled quarterly, 10 HBMN stations will be sampled bimonthly, and 2 will be sampled monthly. All HBMN samples will be analyzed for the same properties and constituents as NASQAN samples. The field measurements and analytical schedules used for the HBMN program are therefore the same as for the NASQAN program. Trace metals samples will be collected at the 55 water-quality Benchmark stations on a quarterly basis. The analytical schedules remain the same. Analysis of radiochemicals at the 55 water-quality Benchmark stations will be on a semiannual basis (1 high-flow and 1 low-flow sample). The specific conductance is likely to exceed 2,000 uS/cm at only one HBMN station - the Bear Den Creek at Mandaree, ND (06332515). Therefore, this station may require schedule 177 for analysis of quarterly dissolved common and trace inorganic constituents. All other stations will require use of schedule 176 for analysis of these constituents. HBMN Sampling Schedule for FY 1991 Please notify the Office of Water Quality if the District responsible for collection of samples for any HBMN station has changed recently and is therefore incorrectly listed in Appendix A.
