Common use of LIMITS OF ERROR, AND PENALTIES RELATED THERETO Clause in Contracts

LIMITS OF ERROR, AND PENALTIES RELATED THERETO. Limits of error for the common dissolved constituents in aqueous samples are defined in the following schedule, which shall apply to the determination of satisfactory accuracy or precision in analyses for these components: Calcium 5% or 1.5 mg/1, whichever is greater Magnesium 6% or 1.5 mg/1, whichever is greater Sodium 5% or 2.0 mg/1, whichever is greater Potassium 5% or 1.0 mg/1, whichever is greater Chloride 5% or 1.0 mg/1, whichever is greater Sulfate 5% or 1.0 mg/1, whichever is greater Fluoride 10% or 0.1 mg/1, whichever is greater Boron 5% or 0.2 mg/1, whichever is greater Silica 10% or 2.0 mg/1, whichever is greater Nitrate + Nitrite as NO3 10% or 1.0 mg/l whichever is greater Total Phosphorus as PO4 20% or 0.20 mg/l whichever is greater Orthophosphate as P 20% or 0.20 mg/l whichever is greater Ammonia Nitrogen 20% or 0.20 mg/l whichever is greater Total Kjeldahl Nitrogen 20% or 0.20 mg/l whichever is greater Ag, As, Be, Cd, Cr, Cu, Fe, Hg, Mn, Ni, Xx, Xx, Xx, Xx, Xx +25% for concentrations greater than or equal to 5X RDL (See Section 5) MBAS 25% for concentrations greater than or equal to 0.5 mg/l Organophosphorus Pesticides Concentrations cannot be beyond certified QC performance limits as provided by the reference material vendor SemiVolatile Organic Carbon and Polycyclic Aromatic Hydrocarbons Concentrations cannot be beyond certified QC performance limits as provided by the reference material vendor Oil & Grease Concentrations cannot be beyond certified Constituent Allowable Error QC performance limits as provided by the reference material vendor Ion Balance (Gen. Mineral) 0.5 milli-equivalents per liter or 5% whichever is greater 1. In the case of analytical parameters not listed above, determinations of satisfactory accuracy and/or precision may be made by County, on notification of Contractor, from information in the latest edition of "Standard Methods," or from other reputable publications. For samples prepared from Quality Control (QC) or Proficiency Testing (PT) standards, performance thresholds based on the allowable performance acceptance limits certified by the vendor will be used as the criteria for acceptability of results. In the case of deviation from true values for known composition samples submitted by County for accuracy quality control, County may, at its option, either notify Contractor, if County believes the error is of a random nature or submit to Contractor another known sample. If the error in analyses exceeds the allowable error limits as described in the preceding table, County may require Contractor to re-analyze, for the constituent in question, or all samples within the same batch as the QA/QC check sample. These follow-up analyses must be conducted by Contractor at the sole expense of Contractor. Refusal by Contractor to re-analyze for constituent(s) in question as requested by County will result in an automatic 10% discount to the entire Contractor invoice for that sample batch. On the second occurrence of Contractor failing to meet accuracy quality control, within 60 days (based on sample submittal date), of excessive error in analysis for the same constituent, Contractor’s invoice(s), for all individual analyses for that constituent and group analyses containing those individual analyses conducted on samples submitted during the calendar month of the initial error, shall be discounted in accordance with the following table: 1.1 - 1.2 20 1.2 - 1.3 30 1.3 - 1.4 40 Over 1.4 50 In the case of reporting limits deviating from specified Maximum Acceptable Reporting Limits, County will notify Contractor of reporting error. County may require Contractor to re-analyze, for the constituent in question, or all samples within the same batch. Follow-up analyses must be conducted by Contractor or may be subcontracted to an ELAP certified laboratory capable of meeting the Maximum Acceptable Reporting Limits at the sole expense of Contractor. Refusal by Contractor to re-analyze for constituent(s) in question as requested by County will result in an automatic 10% discount to the entire Contractor invoice for that sample batch. County understands the technical issues associated with the Maximum Acceptable Reporting Limits in specific categories of analyses, especially in difficult environmental matrices, and will work with Contractor to ensure positive progress is made in a timely manner to resolve reporting limits problems. Contractor must notify County prior to performing analyses if Maximum Acceptable Reporting Limits cannot be achieved. Any exceptions to Maximum Acceptable Reporting Limits need to be listed as Exceptions to Attachments and include all of the following: proposed EPA Method number, method detection limits, holding time, minimum sample volume needed for analysis, and preservation requirement PDF and EDR reports shall be reported to the County no later than 4 weeks after samples are submitted to the lab. Failure to submit within this time shall result in a 10% penalty per week from amount due on 30 day invoice. Submittal of pdf and EDR files shall be subject to reporting timeframes as described above. EDR files shall also be subject to a maximum allowable error rate of 0.1% of the total data values within the respective EDR.

For samples prepared from Quality Control (QC) or Proficiency Testing (PT) standards, performance thresholds based on the allowable performance acceptance limits certified by the vendor will be used as the criteria for acceptability of results. In the case of deviation from true values in excess of the detection limits outlined above, for samples of known composition samples submitted by County COUNTY for accuracy quality control, County may, COUNTY may (at its option, either notify Contractor) either: • Notify CONTRACTOR, if County COUNTY believes the error is of a random nature nature, or submit • Submit to Contractor another known sample. If the error in analyses exceeds the allowable error limits as described in the preceding table, County may require Contractor to re-analyzeCONTRACTOR, for the constituent in questionanalysis, or all samples within the same batch as the QA/QC check sample. These follow-up analyses must be conducted by Contractor at the sole expense another sample of Contractor. Refusal by Contractor to re-analyze for constituent(s) in question as requested by County will result in an automatic 10% discount to the entire Contractor invoice for that sample batchknown composition. On the second occurrence of Contractor failing to meet accuracy quality control, within 60 days (based on sample submittal date), of such excessive error in analysis within two consecutive quarters, CONTRACTOR’s invoices for the same constituent, Contractor’s invoice(s), for all individual analyses for that constituent and group analyses containing those individual analyses conducted on samples submitted during the calendar month of the initial error, one quarter shall be discounted in accordance with the following table: Average of Ratios of Errors to Allowable Errors % Discount 1.0 – 1.1 - 10 1.1 – 1.2 20 1.2 - 1.3 30 1.3 - 1.4 40 Over 1.4 50 In the case of reporting limits deviating from specified Maximum Acceptable Reporting Limits, County will notify Contractor of reporting error. County may require Contractor to re-analyze, for the constituent in question, or all samples within the same batch. Follow-up analyses must be conducted by Contractor or may be subcontracted to an ELAP certified laboratory capable of meeting the Maximum Acceptable Reporting Limits at the sole expense of Contractor. Refusal by Contractor to re-analyze for constituent(s) in question as requested by County will result in an automatic 10% discount to the entire Contractor invoice for that sample batch. County understands the technical issues associated with the Maximum Acceptable Reporting Limits in specific categories of analyses, especially in difficult environmental matrices, and will work with Contractor to ensure positive progress is made in a timely manner to resolve reporting limits problems. Contractor must notify County prior to performing analyses if Maximum Acceptable Reporting Limits cannot be achieved. Any exceptions to Maximum Acceptable Reporting Limits need to be listed as Exceptions to Attachments and include all of the following: proposed EPA Method number, method detection limits, holding time, minimum sample volume needed for analysis, and preservation requirement PDF and EDR reports shall be reported to the County no later than 4 weeks after samples are submitted to the lab.
