Section 0400-45-01-.14 - LABORATORY CERTIFICATION

(1) General

(a) For the purpose of determining compliance with physical, chemical, biological and radiological constituents and maximum contaminant levels set forth in this rule chapter, analyses of samples may be considered only if they have been analyzed by a laboratory certified by the Department. Laboratories which are certified by the Department are designated "state-certified laboratories." Analysis for turbidity, free chlorine residual, temperature, pH, alkalinity, calcium, conductivity, orthophosphate, daily chlorite, and silica may be performed by persons approved by the Department. Approved methodology must be used.

(b) The Tennessee Laboratory Certification Program is established for the purpose of evaluating laboratories to determine technical capability to analyze for one or more groups of the contaminants, disinfectant residuals, disinfection byproducts and disinfectant precursors listed in Rules 0400-45-01-.06 through 0400-45-01-.10, 0400-45-01-.12, 0400-45-01-.21, 0400-45-01-.24 through 0400-45-01-.26, and 0400-45-01-.36 through 0400-45-01-.40. Department laboratory certification officer(s) shall be experienced professional staff members of the Department of Environment and Conservation, Division of Water Resources and certified by the U.S. Environmental Protection Agency. Certification officer(s) shall supervise the certification program.

(c) A laboratory desiring certification in microbiological and/or chemical analysis shall make written application to the Department of Environment and Conservation, Division of Water Resources. The applicant shall indicate those group(s) of contaminants for which it seeks certification:

(d) The laboratory shall upon request supply to the Department all information requested concerning its equipment, facilities, data, and the qualifications of its laboratory staff. Certified laboratories must have an on-site audit conducted every three years by the certification officer or his/her designee.

(e) A laboratory desiring certification will arrange for an American Association for Laboratory Accreditation (A2LA) approved vendor to send performance evaluation samples to the laboratory for testing pursuant to its proficiency testing program. A2LA approved Performance Evaluation venders can be viewed at: http://www.a2la.org/dirsearchnew/nelacptproviders.cfm. The laboratory's performance in correctly evaluating such sample(s) will be sent to both the laboratory and to the certification officer. All direct costs for the performance evaluation samples will be borne by the laboratory requesting certification.

(f) The certification officer shall review the written report of the laboratory performance evaluation and together with his review of requirements set forth in this rule shall determine the certification ranking.

(g) Certified laboratories must maintain all records and correspondence used to determine compliance with the requirements of these Rules for a period of not less than six (6) years. Adequate information must be available to reconstruct results for compliance and performance evaluation (PE) samples. This includes all raw data, calculations, and quality control data. Electronic data must be backed up by protected tape, hard disk, or other method approved by the Department. Water system clients should be notified before disposing of any records so that they may request copies if needed. Performance evaluation samples shall be analyzed annually.

(h) Certified Laboratories shall comply with all requirements set forth in the latest edition of EPA Manual for the Certification of Laboratories Analyzing Drinking Water except where those requirements differ from the requirements set forth in this chapter.

(2) In order for a laboratory to be certified by the Department:

(a) It must have a written quality assurance (QA) plan which addresses the following parts:

1. Laboratory organization and responsibility.

2. Process used to identify clients' Data Quality Objectives.

3. Standard Operating Procedures with dates of last revision.

4. Field sampling procedures.

5. Laboratory sample receipt and handling procedures.

6. Instrument calibration procedures.

7. Analytical procedures.

8. Data reduction, validation, reporting and verification.

9. Type of quality control (QC) checks and the frequency of their use.

10. List schedules of internal and external system and data quality audits and inter-laboratory comparisons.

11. Preventive maintenance procedures and schedules.

13. Record keeping procedures.

(i) If a particular part is not relevant, the QA plan should state this and provide a brief explanation.

(ii) All laboratories analyzing drinking water compliance samples must adhere to any required QC procedures specified in the approved method. Documentation for many of the listed QA plan parts may be made by reference to appropriate sections of the latest edition of EPA Manual for the Certification of Laboratories Analyzing Drinking Water, the laboratory's standard operating procedures (SOPs), or other literature (e.g., promulgated methods, Standard Methods for the Examination of Water and Wastewater, etc.). The QA Plan should be updated at least annually.

(b) It must complete the performance evaluation samples as described in paragraph (9) of this rule.

(c) On an annual basis and with each application for certification or recertification, all laboratories except Tennessee public water systems shall convey to the Department, Division of Water Resources, payment for the activities necessary for each group of contaminants for which it desires certification or recertification. All laboratories except Tennessee public water systems shall pay annually an administrative certification fee as listed in the fee schedule. The fee schedule is as follows:

12. Enterococci	$500

(i) Certification fees shall be retained by the Department even if the laboratory applying for certification does not qualify for certification.

(ii) If the certification fee is not paid within 30 days after the receipt of the invoice, certification of the laboratory is automatically revoked.

(iii) The reinstatement fee for a laboratory that fails to pay its certification fee by the invoice due date shall be $500 in addition to the fees specified in this subparagraph.

(3) Ranking Scheme of Laboratories - Based upon a review of the written application, the facts determined from any inspection, and the results of a laboratory performance evaluation, a certification officer may classify a laboratory as follows for the particular group(s) of contaminants for which it seeks certification:

(a) Certified - A laboratory that meets the minimum requirements as set forth in these rules.

(b) Provisionally Certified - A laboratory which has deficiencies but can still produce valid analytical data.

(c) Not Certified - A laboratory which possesses major deficiencies such that it cannot consistently produce valid analytical data in order to determine compliance with the maximum contaminant level. Analytical data will not be accepted from a laboratory with this ranking.

(d) Interim Certification - Interim certification may be granted in certain circumstances when it is impossible or unnecessary to perform an on-site audit. Interim certification status may be granted if, for example, the Certification Officer determines that the laboratory has the appropriate instrumentation, is using the approved methods, has adequately trained personnel to perform the analyses, and has satisfactorily analyzed PE samples, if available, for the contaminants in question. The Certification Officer should perform an on-site audit as soon as possible but no later than three years. An example of a situation where this type of certification is warranted would be a laboratory that has requested certification for the analysis of additional analytes that involve a method for which it already has certification.

(4) Downgrading Certification Status - A laboratory certified to perform analyses may be downgraded to a Provisionally Certified status for a particular parameter, or for one or more groups of contaminants for which it has been certified for any one of the following reasons:

(a) Failure to analyze a set of performance evaluation samples within established acceptance limits described in paragraph (9) of this rule. If more than one concentration of a particular contaminant was provided for analysis, the laboratory must analyze all concentrations provided except where otherwise stated.

(b) Failure to notify the Department within 30 days of any changes either in personnel, equipment, or laboratory location which may impair analytical capability.

(c) Failure to maintain the minimum required standard of quality as contained in the most recent version of the EPA Manual for the Certification of Laboratory Analyzing Drinking Water as determined by an on-site evaluation by a Department representative.

(d) During a provisional status period, which may last for up to one year plus any extension period pending proceedings for revocation of its certification, the laboratory may continue to analyze samples for compliance purposes, but it must notify its clients of its downgraded status in writing on all reports.

(e) Failure to report compliance data to the public water system or the Department in a timely manner. Data that may cause the system to exceed a MCL shall be reported as soon as possible to the system and to the Department.

(5) Revoking Certification Status - A laboratory certified to perform analyses may be downgraded from a Certified or a Provisionally Certified status to a Not Certified status for a particular parameter, or for one or more groups of contaminants for which it has been certified, including but not limited to any of the reasons listed in subparagraphs below. Commercial laboratories must notify their public water system customers of the change in certification status by mail within 45 days of a downgrade in status by the Department and retain copies of such notice for six years.

(a) Failure to analyze an initial and a follow-up or cross check performance evaluation sample within established acceptance limits.

(b) Failure to correct identified deviations (including continued use of unapproved methods and equipment) within the time specified by the Department.

(c) Reporting as data derived from its own laboratory analysis, that data obtained from analyses of the sample(s) performed by another laboratory.

(d) Falsification or inaccurate reporting of analytical data.

(e) Failure to report to the Department analytical results as specified by Rule 0400-45-01-.18. Analytical results must be submitted on forms furnished by the Department. Forms may be obtained from the Division of Water Resources. A certified laboratory shall submit results of its analyses to both the appropriate Department's field office and the Department's central office.

(f) Failure to perform the analysis within the time period prescribed by the analytical procedure. However, the time period shall not be more than thirty (30) days from the sample collection date, except for lead and copper tap samples collected pursuant to Rule 0400-45-01-.33.

(g) Failure to notify its drinking water customers of any downgrade or revocation of its certification status and to keep records of the notice to customers.

(h) Failure of the laboratory to reject any sample taken for compliance purposes that does not meet acceptable criteria for the type container and preservative, maximum holding time, chain of custody, proper sample collection and transport, and sample report form that contains the location, date, time of collection, collector's name, preservative added, and other special remarks concerning the sample. Indelible ink shall be used for completing the sample report form.

(i) Failure of the Laboratory Director to give timely notice to the party responsible for collecting the sample that improper sampling technique, container, transport, holding time, method preservative or documentation was used.

(j) Failure to provide written sampling procedures with sample containers sent to customers for collecting drinking water samples.

(k) Failure to meet the method detection limits.

(l) Failure to maintain all data necessary to reconstruct analytical results reported for compliance samples.

(m) Failure to pay certification fees as listed in subparagraph (2)(c) of this rule.

(6) Procedure for Revocation

(a) The Department or the certification officer shall notify the laboratory by certified mail of its intent to revoke certification.

(b) If the local laboratory objects to the determination to revoke certification, the laboratory shall submit a written notice of appeal to the Department within thirty (30) days after issuance of the notice of intent to revoke certification. The notice of appeal will be referred to the Tennessee Water Quality Control Board. The Board will set a hearing date and conduct proceedings in accordance with the Uniform Administrative Procedures Act, Chapter 5 of Title 4. If no notice of appeal is so filed, certification will be revoked.

(c) The notice of appeal shall set forth the grounds and reasons for objection and shall ask for a hearing before the Tennessee Water Quality Control Board. It shall be signed by a duly authorized representative of the laboratory such as the president/owner of a commercial laboratory, or the mayor, utility manager, president, or laboratory supervisor in the case of a municipal or utility district laboratory.

(d) If the Water Quality Control Board modifies or sets aside the determination of the Department, the Department will reevaluate the local laboratory within sixty (60) days of issuance of the decision by the Board.

(7) Reinstatement of Certification - Certification of a laboratory will be reinstated when it demonstrates to the Department that the deficiencies which resulted in provisional certification or revocation have been corrected. Such demonstration may result from an on-site evaluation and/or a successful analysis of samples on the next regularly scheduled performance evaluation.

(8) Reciprocity of Certified Laboratories - The Department may authorize acceptance of analyses from laboratories certified by other states or by the U.S. Environmental Protection Agency. Authorization will be granted on a reciprocal basis for laboratories from those states which accept Tennessee laboratory certification. Laboratories desiring Department approval of their certification from the U.S. E.P.A. or from another state must submit to the Department copies of all correspondence pertaining to the grant of certification, including the results of any performance evaluation sample analyses.

(9) Proficiency Evaluation (PE) Samples or Performance Test (PT) Samples

(a) In order to receive and maintain full certification for an analyte, the following are required for each analyte for which a laboratory is certified:

1. The laboratory must analyze PE samples (if available) acceptable to the Department at least once a year for each analyte and by each method used to analyze compliance samples. PE samples are also referred to as Performance Test (PT) samples.

2. Results from analysis of the PE samples must be within the acceptable limits set forth in this chapter.

3. The laboratory must document the corrective actions taken when a PE sample is analyzed unsuccessfully. A copy of this documentation must be available for review by the certification officer.

4. A make up PE sample must be successfully analyzed within three months of being notified that a PE sample was not acceptable.

(b) Excluding vinyl chloride, the laboratory may be certified for all VOCs if they successfully analyze at least 80% of the regulated VOCs. The 80% Rule does not apply to the regulated trihalomethanes (THM) or haloacetic acids (HAAs). Laboratories are certified for total THMs and HAA5 but each regulated THM and HAA concentration must be reported, evaluated and passed individually to pass the PE sample. If a laboratory fails one of the regulated THMs or HAAs, it cannot be certified for total THMs or HAA5, but must analyze another PE sample and pass all of the regulated THMs or HAAs in a PE sample to be certified to analyze compliance monitoring samples for total trihalomethanes or total haloacetic acids.

The following table summarizes the 80% Rule.

Analyte(s)	PE Success Requirement
Vinyl Chloride	100%
20 VOCs	80% *
4 Regulated THMs	100%
5 Regulated HAA5s	100%

*A lab will not maintain certification for analyte(s) which it repeatedly fails.

(c) Acceptable studies for the determination of total coliforms and E. coli shall be part of a drinking water study. Each study shall contain a set of ten samples in various combinations of total coliforms, E. coli, non-coliforms, and at least one blank. To be certified, laboratories must successfully analyze nine of the ten samples with no false negatives.

(10) Analytical Requirements

(a) Microbiology

1. Suppliers of water for community water systems and non-community water systems shall analyze for coliform bacteria for the purpose of determining compliance with paragraph (4) of Rule 0400-45-01-.06. The standard sample volume required for total coliform analysis, regardless of the analytical method used is 100 milliliters. Analyses shall be conducted in accordance with one of the analytical methods in following table:

2. Where a determination of fecal coliform density is not required, public water systems must conduct fecal coliform analysis in accordance with the following procedure:

(i) When the MTF Technique or Presence-Absence (P-A) Coliform Test is used to test for total coliforms, shake the lactose-positive presumptive tube or P-A bottle vigorously and transfer the growth with a sterile 3-mm loop or sterile applicator stick into brilliant green lactose bile broth and EC medium to determine the presence of total and fecal coliforms, respectively.

(ii) For EPA-approved analytical methods which use a membrane filter, remove the membrane containing the total coliform colonies from the substrate with a sterile forceps and carefully curl and insert the membrane into a tube of EC medium (The laboratory may first remove a small portion of selected colonies for verification), swab the entire surface with a sterile cotton swab and transfer the inoculum to EC medium (do not leave the cotton swab in the EC medium), or inoculate individual total coliform-positive colonies into EC Medium. Gently shake the inoculated EC tubes to insure adequate mixing and incubate in a waterbath at 44.5 + 0.2°C for 24 + 2 hours. Gas production of any amount in the inner fermentation tube of the EC medium indicates a positive fecal coliform test. The preparation of EC medium is described in Method 9221E in Standard Methods for the Examination of Water and Wastewater, 18th Edition (1992), 19th Edition (1995), and 20th Edition (1998); the cited method in any one of these three editions may be used.

3. Public Water Systems choosing to test for E. coli in lieu of fecal coliform must use the following methods:

(i) EC medium supplemented with 50 ug/ml of 4-methylumbelliferyl-beta-D-glucuronide (MUG) (final concentration), as described in Method 9222 G in Standard Methods for the Examination of Water and Wastewater, 19th edition (1995) and 20th edition (1998). Either edition may be used. Alternatively, the 18th edition (1992) may be used if at least 10 ml of EC medium, as described in part 2 of this subparagraph, is supplemented with 50 ug/ml of MUG before autoclaving. The inner inverted fermentation tube may be omitted. If the 18th edition is used, apply the procedure in part 2 of this subparagraph for transferring a total coliform-positive culture to EC medium supplemented with MUG, incubate the tube at 44.5 + 0.2°C for 24 + 2 hours, and then observe fluorescence with an ultraviolet light (366nm) in the dark. If fluorescence is visible, E. coli are present.

(ii) Nutrient agar supplemented with 100 µg/ml of 4methylumbelliferyl-beta-D-glucuronide (MUG) (final concentration), as described in Method 9222G in Standard Methods for the Examination of Water and Wastewater, 19th edition (1995) and 20th edition (1998). Either edition may be used for determining if a total coliform-positive sample, as determined by a membrane filter technique, contains E. coli Alternatively, the 18th edition (1992) may be used if the membrane filter containing a total coliform-positive colony(ies) is transferred to nutrient agar, as described in Method 9221B (paragraph 3) of Standard Methods (18th edition), supplemented with 100 ug/ml of MUG. If the 18th edition is used, incubate the agar plate at 35°C for 4 hours and then observe the colony(ies) under ultraviolet light (366 nm) in the dark for fluorescence. If fluorescence is visible, E. coli are present.

(iii) Minimal Medium ONPG-MUG (MMO-MUG) Test, as set forth in the article "National Field Evaluation of Defined Substrate Method for the Simultaneous Detection of Total Coliforms and Escherichia coli from Drinking Water; Comparison with Presence-Absence Techniques" (Edberg et al.), Applied and Environmental Microbiology, Volume 55, pp. 1003-1008, April 1989. (Note: The Autoanalysis Colilert System is an MMO-MUG test). If the MMO-MUG test is total coliform-positive after a 24-hour incubation, test the medium for fluorescence with a 366-nm ultraviolet light (preferably with a 6-watt lamp) in the dark. If fluorescence is observed, the sample is E. coli-positive. If fluorescence is questionable (cannot be definitively read) after 24 hours incubation, incubate the culture for an additional four hours (but not to exceed 28 hours total) and again test the medium for fluorescence. The MMO-MUG Test with hepes buffer in lieu of phosphate buffer is the only approved formulation for the detection of E. coli.

(iv) The Colisure Test. A description of the Colisure Test may be obtained from the Millipore Corporation, Technical Services Department, 80 Ashby Road, Bedford, MA 01730.

(v) The membrane filter method with MI agar, a description of which is cited in footnote 6 to table 0400-45-01-.14(10)(a) 1.

(x) Colitag^®, a description of which is cited in footnote 14 to table 0400-45-01-.14(10)(a) 1.

(xi) As an option to subpart (iii) of this part, a system with a total coliform-positive, MUG-negative, MMO-MUG test may further analyze the culture for the presence of E. coli by transferring a 0.1 ml. 28-hour MMO-MUG culture to EC Medium + MUG with a pipet. The formulation and incubation conditions of EC Medium + MUG, and observation of the results are described in subpart (i) of this part. Alternative methods are given in the following table:

1. The method must be specified when results are reported.

2. Tests must be conducted to provide organism enumeration (density). Select the appropriate configuration of tubes/filtrations and dilutions/volumes to account for the quality, character, consistency, and anticipated organism density of the water sample.

3. To assess the comparability of results obtained with individual methods, it is suggested that side-by-side tests be conducted across seasons of the year with the water samples routinely tested in accordance with the most current Standard Methods for the Examination of Water and Wastewater or EPA alternate test procedure (ATP) guidelines.

12. Unfiltered, no digestion or hydrolysis.

13. Because MDLs reported in EPA Methods 200.7 and 200.9 were determined using a 2x preconcentration step during sample digestion, MDLs determined when samples are analyzed by direct analysis (i.e., no sample digestion) will be higher. For direct analysis of cadmium and arsenic by Method 200.7, and arsenic by Method 3120 B, sample preconcentration using pneumatic nebulization may be required to achieve lower detection limits. Preconcentration may also be required for direct analysis of antimony, lead, and thallium by Method 200.9; antimony and lead by Method 3113 B; and lead by Method D3559-90D, unless multiple in-furnace depositions are made.

14. If ultrasonic nebulization is used in the determination of arsenic by Methods 200.7, 200.8, or SM 3120 B, the arsenic must be in the pentavalent state to provide uniform signal response. For Methods 200.7 and 3120 B, both samples and standards must be diluted in the same mixed acid matrix concentration of nitric and hydrochloric acid with the addition of 100 ± L of 30% hydrogen peroxide per 100 mL of solution. For direct analysis of arsenic with Method 200.8 using ultrasonic nebulization, samples and standards must contain 1 mg/L of sodium hypochlorite.

1. Laboratories must achieve a method detection limit for lead of 0.001 mg/l according to the procedures in appendix B of part 136 of 40 CFR. This need only be accomplished if the laboratory will be processing source water composite samples under subpart (9)(a)1.(iv) of Rule 0400-45-01-.33.

(i) Lead: 0.001 mg/l (only if source water compositing is done under Rule 0400-45-01-.09 ); and

(ii) Copper: 0.001 mg/l or 0.020 mg/l when atomic absorption direct aspiration is used (only if source water compositing is done under Rule 0400-45-01-.09 ).

2. The Department has the authority to allow the use of previously collected monitoring data, provided that the laboratory is currently certified by EPA or the Department to perform analyses to the specifications required in this subparagraph and if the data were collected and analyzed in accordance with the requirements of this rule and Rule 0400-45-01-.33.

3. All lead levels measured between the PQL and the MDL must be either reported as measured or they can be reported as one-half the PQL (0.0025 mg/l). All levels below the lead MDL must be reported as zero; and

4. All copper levels measured between PQL and the MDL must be either reported as measured or they can be reported as one-half the PQL (0.025 mg/l). All levels below the copper MDL must be reported as zero.

(e) Laboratories must analyze PE samples within the following acceptance criteria:

Contaminant	Acceptance limit
Antimony	±30 at >=0.006 mg/l
Arsenic	±30 at >=0.003 mg/l
Asbestos	2 standard deviations based on study statistics
Barium	±15% at >=0.15 mg/l

Footnotes

1. For cyanide determinations samples must be adjusted with sodium hydroxide to pH 12 at the time off collection. When chilling is indicated the sample must be shipped and stored at 4°C or less. Acidification of nitrate or metals samples may be with a concentrated acid or a dilute (50% by volume) solution of the applicable concentrated acid. Acidification of samples for metals analysis is encouraged and allowed at the laboratory rather than at the time of sampling provided the shipping time and other instructions in Section 8.3 of EPA Methods 200.7 or 200.8 or 200.9 are followed.

2. P=plastic, hard or soft; G=glass, hard or soft.

3. In all cases samples should be analyzed as soon after collection as possible. Follow additional (if any) information on preservation, containers or holding times that is specified in method.

4. Instructions for containers, preservation procedures and holding times as specified in Method 100.2 must be adhered to for all compliance analyses including those conducted with Method 100.1.

5. If the sample is chlorinated, the holding time for an unacidified sample kept at 4°C is extended to 14 days.

6. Nitrate-Nitrite refers to a measurement of total nitrate.

(g) Certified Laboratories performing analyses for Public Water Systems as required by this Chapter must utilize an approved method for Organic Contaminants listed in table 0400-45-01-.14(10)(g) or the altenative testing methods in table A in this subparagraph:

1. Previously approved EPA methods remain available for compliance monitoring until June 1, 2001. EPA methods 502.2 Rev. 2.0, 505 Rev. 2.0, 507 Rev. 2.0, 508 Rev. 3.0, 531.1 Rev. 3.0 are in "Methods for the Determination of Organic Compounds in Drinking Water", December 1988, revised July 1991; methods 506 and 551 are in "Methods for the Determination of Organic Compounds in Drinking Water--Supplement I", July 1990; methods 515.2 Rev. 1.0 and 524.2 Rev. 4.0 are in "Methods for the Determination of Organic Compounds in Drinking Water--Supplement II,'' August 1992; and methods 504.1 Rev. 1.0, 508.1 Rev. 1.0, 525.2 Rev.1.0 are available from US EPA NERL, Cincinnati, OH 45268

2. Substitution of the detector specified in Method 505, 507, 508, or 508.1 for the purpose of achieving lower detection limits is allowed as follows: Either an electron capture or nitrogen phosphorus detector may be used provided all regulatory requirements and quality control criteria are met.

3. PCBs are qualitatively identified as Aroclors and measured for compliance purposes as decachlorobiphenyl. Users of Method 505 may have more difficulty in achieving the required detection limits than users of Methods 508.1, 525.2 or 508.

4. Accurate determination of the chlorinated esters requires hydrolysis of the sample as described in EPA Methods 515.1, 515.2, 515.3, 515.4, and 555 and ASTM Method D 5317-93, 98 (Reapproved 2003).

5. This method may not be used for the analysis of atrazine in any system where chlorine dioxide is used for drinking water treatment. In samples from all other systems, any result for atrazine generated by Method AG-625 that is greater than one-half the maximum contaminant level (MCL) (in other words, greater than 0.0015mg/L or 1.5µ/L) must be confirmed using another approved method for this contaminant and should use additional volume of the original sample collected for compliance monitoring. In instances where a result from Method AG-625 triggers such confirmatory testing, the confirmatory result is to be used to determine compliance.

¹ The calibration curve must encompass the regulatory minimum reporting level (MRL) concentration. Data may be reported for concentrations lower than the regulatory MRL as long as the precision and accuracy criteria are met by analyzing an MRL check standard at the lowest reporting limit chosen by the laboratory. The laboratory must verify the accuracy of the calibration curve at the MRL concentration by analyzing an MRL check standard with a concentration less than or equal to 110% of the MRL with each batch of samples. The measured concentration for the MRL check standard must be ±50% of the expected value, if any field sample in the batch has a concentration less than 5 times the regulatory MRL. Method requirements to analyze higher concentration check standards and meet tighter acceptance criteria for them must be met in addition to the MRL check standard requirement.

² When adding the individual trihalomethane or haloacetic acid concentrations to calculate the TTHM or HAA5 concentrations, respectively, a zero is used for any analytical result that is less than the MRL concentration for that DBP, unless otherwise specified by the Department.

4. Additional analytical methods. Systems required to analyze parameters not included in subparagraph (i) and part (k)1. of this paragraph must use the following methods. A party approved by the EPA or the Department must measure these parameters.

(i) Alkalinity. All methods allowed in subparagraph (c) of this paragraph for measuring alkalinity.

(ii) Bromide. EPA Methods 300.0, 300.1, 317.0 Revision 2.0, 326.0, or ASTM D 6581-00.

(iii) Total Organic Carbon (TOC). Standard Method 5310 B or 5310 B-00 (High-Temperature Combustion Standard Method) or Standard Method 5310 C or 5310 C-00 (Persulfate-Ultraviolet or Heated-Persulfate Oxidation Method) or Standard Method 5310 D or 5310 D-00 (Wet-Oxidation Method) or EPA Method 415.3 Revision 1.1. Inorganic carbon must be removed from the samples prior to analysis. TOC samples may not be filtered prior to analysis. TOC samples must be acidified at the time of sample collection to achieve pH less than or equal to 2 with minimal addition of the acid specified in the method or by the instrument manufacturer. Acidified TOC samples must be analyzed within 28 days. The alternative testing methods for TOC are High Temperature Combustion, Standard Method 5310 B 21^st edition (2005) or EPA Method 415.3, Revision 1.2; Persulfate-Ultraviolet or Heated Persulfate Oxidation, Standard Method 5310 C 21^st edition (2005) or EPA Method 415.3, Revision 1.2; or Wet Oxidation, Standard Method 5310 D 21^st edition (2005) or EPA Method 415.3, Revision 1.2.

(iv) Specific Ultraviolet Absorbance (SUVA). SUVA is equal to the UV absorption at 254 nm (UV254) (measured in m^-1 divided by the dissolved organic carbon (DOC) concentration) (measured as mg/L). In order to determine SUVA, it is necessary to separately measure UV254 and DOC. When determining SUVA, systems must use the methods stipulated in item (I) of this subpart to measure DOC and the method stipulated in item (II) of this subpart to measure UV254. SUVA must be determined on water prior to the addition of disinfectants/oxidants by the system. DOC and UV254 samples used to determine a SUVA value must be taken at the same time and at the same location. The alternative testing method for SUVA is Calculation using DOC and UV254 data, EPA Method 415.3, Revision 1.2.

(I) Dissolved Organic Carbon (DOC). Standard Method 5310 B or 5310 B-00 (High-Temperature Combustion Method) or Standard Method 5310 C or 5310 C-00 (Persulfate-Ultraviolet or Heated-Persulfate Oxidation Method) or Standard Method 5310 D or 5310 D-00 (Wet-Oxidation Method) or EPA Method 415.3 Revision 1.1. DOC samples must be filtered through the 0.45 µm pore-diameter filter as soon as practical after sampling, not to exceed 48 hours. After filtration, DOC samples must be acidified to achieve pH less than or equal to 2 with minimal addition of the acid specified in the method or by the instrument manufacturer. Acidified DOC samples must be analyzed within 28 days of sample collection. Inorganic carbon must be removed from the samples prior to analysis. Water passed through the filter prior to filtration of the sample must serve as the filtered blank. This filtered blank must be analyzed using procedures identical to those used for analysis of the samples and must meet the following criteria: DOC < 0.5 mg/L. The alternative testing methods for DOC are High Temperature Combustion, Standard Method 5310 B 21^st edition (2005) or EPA Method 415.3, Revision 1.2; Persulfate-Ultraviolet or Heated Persulfate Oxidation, Standard Method 5310 C 21^st edition (2005) or EPA Method 415.3, Revision 1.2; or Wet Oxidation, Standard Method 5310 D 21^st edition (2005) or EPA Method 415.3, Revision 1.2.

(II) Ultraviolet Absorption at 254 nm (UV254). Standard Method 5910 B or 5910 B-00 (Ultraviolet Absorption Method) or EPA Method 415.3 Revision 1.1. UV absorption must be measured at 253.7 nm (may be rounded off to 254 nm). Prior to analysis, UV254 samples must be filtered through a 0.45 µm pore-diameter filter. The pH of UV254 samples may not be adjusted. Samples must be analyzed as soon as practical after sampling, not to exceed 48 hours. The alternative testing method for UV254 is Spectrophotometry, Standard Method 5910 B 21 ^st edition (2005) or EPA Method 415.3, Revision 1.2.

(v) pH. All methods allowed in table 0400-45-01-.14(10)(c) for measuring pH.

(vi) Magnesium. All methods allowed in table 0400-45-01-.14(10)(c) for measuring magnesium.
