MDH Well Management: Private Well Owner Brochures

A 2016 Minnesota Department of Health survey found that 43 percent of people who get their drinking water from a private well look to water testing laboratories for information about how to manage well safety and water quality. The MDH Environmental Health Division has the following brochures that can help inform private well users how to manage their well and when and how to test their well water.

  • Well Water and Your Baby is a brand new brochure for households that get their drinking water from a private well and have or will have a baby in the home. It discusses the importance of well testing.
  • Owners Guide to Wells is a brochure for households that get their drinking water from a private well. It explains the well user’s responsibilities to regularly test their well water, inspect their well for damage, protect their well from damage, and seal unused wells.

Well Management hopes your laboratory will help share the brochures with customers who have private wells and that the brochures help answer some of the questions you receive from private well users.  Labs can order the brochures in bulk on the Well Management website (see Order Well Management Program Educational Materials.

Background information about private well users in Minnesota

test your well waterAbout 1.2 million people in Minnesota get their drinking water from a private well. Unlike people who get their drinking water from a public water system, private well users are responsible for making sure their water is safe for everyone in their household to drink. Minnesota Department of Health (MDH) recommends all private well users in Minnesota test for coliform bacteria, nitrate, arsenic, and lead. Depending on who is drinking the water and where the well is, MDH may recommend additional water tests.

A survey MDH conducted in 2016 with nearly 800 households that get their drinking water from a private well found that less than 20 percent of the respondents had tested their well water for anything within the past two years. We look forward to partnering with you to increase the percentage of private well users regularly testing their well

PFCs: Updated Guidance and Analytical Checklist

The Minnesota Pollution Control Agency (MPCA) has revised and updated the Guidance for Perfluorochemicals Analysis (PDF) that includes method guidance and quality control acceptance criteria for Perfluorochemicals (PFC) analysis.  These standards are considered minimum analytical and reporting criteria and address initial and continuing calibration, method validation, method detection limits and reporting limits, and batch quality control.  The Minnesota Department of Health Environmental Laboratory Accreditation Program (MNELAP) has updated the companion Perfluorinated Chemicals (PFCs) Analytical Checklist to help laboratories and assessors when reviewing and meeting the Minnesota PFC analysis and reporting criteria.

Selective Ion Monitoring (SIM)

Moving forward, MNELAP will not offer revised EPA 8260 or 8270 methods with the SIM designation on the available list of fields of testing, but will continue to offer the historic versions of the EPA 8270 SIM methods. The use of Selective Ion Monitoring (SIM) is an allowed enhancement in the EPA 8260 and EPA 8270 methods for achieving lower detection limits or reducing interferences, and does not require the lab to report results using EPA 8260 SIM or EPA 8270 SIM designations. Please ensure the lab reports the fields of testing for which your laboratory maintains on their current scope of accreditation (e.g. method code, method descriptions) and meets the needs of the client.

MDH Well Management: Handling of Water-Supply Water Samples

The MDH Well Management Section revised the handling of water samples memo (PDF), regarding the preservation and handling of water samples collected from new private potable water‐supply wells.  MNELAP laboratories will be assessed for water samples received from new wells in accordance to the revised memorandum dated July 3, 2018.

Excess Sample Volume for Enzyme Substrate Methods: Reject, Pour or Pipette

The Safe Drinking Water Act (40 CFR Part 141.852 (a) (1)) clearly states that the standard sample volume required for total coliform and E.coli analysis, regardless of analytical method used, is 100 ml. If the sample arrives with less than 100 mls the laboratory must reject the sample and contact the client.  If the sample arrives over the 100 ml volume mark the laboratory must inspect the sample and reject the sample, if there is not a one-inch headspace to ensure proper mixing and contact the client or ensure they maintain a compliant procedure for dealing with the excess sample volume.

The EPA’s Manual for the Certification of Laboratories Analyzing Drinking Water (5th edition, 2005) states that at least 100 mls of sample must be collected, allowing at least 1-inch air space to facilitating mixing the sample by shaking.  If the sample bottle is filled too full to allow for proper mixing, do no pour off and discard a portion of the sample. Rather, pour the entire sample into a larger sterile container, mix properly and proceed with the analysis.

The USEPA Region 5 recommends sample rejection for samples with excess sample volume, where possible, and if the sample is analyzed then the lab must ensure the sample is homogenized by shaking in a container with at least a 1-inch headspace.  The homogenized sample must be decanted into a larger sterile container and then poured back into the original container to the 100 ml volume line and the media added.  If there is excess volume, but the container (e.g. 150 ml sterile container) allows for 1-inch of sample mixing space, then the sample may be homogenized and drawn off with a sterile pipette using aseptic technique. However, the concern with pipetting is flocculated bacteria drawn off from the top of a non-homogenized sample, which could lead to false negative results, and to avoid this error ensure thorough mixing prior to pipetting. Document all client contact/decisions.

Vendor Supplies and Services

Recently, there have been some concerns with vendor supplied cadmium reduction columns (nitrate + nitrite) and pre-packaged and pre-prepared nutrient packets for biological oxygen demand (BOD) dilution water.   The 2009 TNI Standard require calibration and traceability to National standards for balances, weights, volumetric, and standard reference materials, but manufacturers do not necessarily need to meet the same requirements and may provide materials for use in an accredited lab that may not meet or always meet the requirements of the method/Standards.  Please continue to evaluate purchased supplies and services per the 2009 TNI Standard:

  • 4.6 Purchasing Services and Supplies (ISO/IEC 17025:2005(E), Clause 4.6)
    • 4.6.1 The laboratory shall have a policy and procedure(s) for the selection and purchasing of services and supplies it uses that affect the quality of the tests and/or calibrations. Procedures shall exist for the purchase, reception and storage of reagents and laboratory consumable materials relevant for the tests
      and calibrations.
    • 4.6.2 The laboratory shall ensure that purchased supplies and reagents and consumable materials that affect the quality of tests and/or calibrations are not used until they have been inspected or otherwise verified as complying with standard specifications or requirements defined in the methods for the tests
      and/or calibrations concerned. These services and supplies used shall comply with specified requirements. Records of actions taken to check compliance shall be maintained.

The 2017 MUR Implementation and the Availability of FOTs

If your laboratory currently maintains or wishes to seek secondary accreditation with New York or New Jersey, please take note that these accreditation bodies plan to implement the 2017 Clean Water Act MUR on April 1 and July 1, 2018.  The early implementation of the 2017 MUR methods may affect your laboratory, because the Minnesota Environmental Laboratory Accreditation Program (MNELAP) may not currently offer accreditation for an updated method required by the secondary Accreditation Body (AB).    

Minnesota labs, interested in secondary accreditation with New York and New Jersey, need to provide MNELAP with a list of fields of testing to evaluation for addition to the MNELAP available list prior to other states’ implementation timelines.  Please supply MNELAP with a list of the needed method reference, TNI LAMS method code, analyte name, TNI LAMs analyte code, program and matrix by March 1, 2018 to be considered for additions to our current list of fields of testing available for accreditation.  

Fall 2017 News

New Fields of Testing Added

The ELDO application has been updated with over 200 fields-of-testing (FOT). The new FOTs include updated method codes to comply with TNI LAMs database, missed FOTs from past years, and updated method versions.

New Field of Testing Request Form

If your laboratory needs accreditation for a field-of-testing that does not appear on the current FOT list, please use the FOT Request Form to send your request directly to MNELAP for review and processing.

Approved Method Version

Please ensure you are using the approved version of the method that is required for your permit, program or rule. For example, laboratories that do compliance work for the Minnesota Pollution Control Agency under the Resource and Conservation Act are required to use the SW-846 Update V versions. Please check the method you are seeking accreditation is the method listed in the Update V, as not all Update V methods are sequential (e.g. EPA 8260 C is not allowed, while EPA 8260 B is allowed). If in doubt, contact the client.
To apply for a newer method version laboratories must ensure the following:

  • The Standard Operating Procedure (SOP) is compliant with the method version requested;,
  • The actual laboratory practice must follow the requirements associated with the method version listed on the renewal application or current scope;
  • Proficiency Tests (PTs) from older method version are acceptable in 2017, but all future PTs must match the method on the laboratory’s scope;
  • For secondary laboratories, an older version of a method listed are accepted on the primary scope as long as the laboratory is in the process of updating to the newest version with their primary accreditation body.
  • Determine if you need to maintain the older version of the method. If not, please remove the older method version from your application prior to submittal.

New Method Detection Limit Procedure Timeline

The 2017 Method Update Rule (MUR) became effective September 27, 2017.  The MNELAP laboratories are required to begin following the new Method Detection Limit (MDL) Procedure in 2018 and have all MDLs completed by the updated procedure by 2019. An on demand training The New MDL Procedure is available for a fee. The webcast reviews the new procedure and provides examples of how to implement the procedure using real data.

The Minnesota Environmental Laboratory Accreditation Program Receives Renewed Recognition as a National Environmental Laboratory Accreditation Program Accreditation Body

The Minnesota Environmental Laboratory Accreditation Program (MNELAP) is an Accreditation Body (AB) established in 1989 to accredit environmental laboratories. MNELAP has been a National Environmental Laboratory Accreditation Program (NELAP) Accreditation Body (AB) through the National Environmental Laboratory Accreditation Council (NELAC) since 2010. In early 2016, MNELAP participated in the triennial evaluation process and NELAC awarded MNELAP renewal recognition as a NELAP AB on April 5, 2017. The evaluation process consists of a thorough record and document review, onsite evaluation of MNELAP, and an observation of a MNELAP assessor performing a laboratory assessment. The NELAP evaluation team assessed the MNELAP’s compliance to the 2009 TNI Standard Volume 2 General Requirements for Accreditation Bodies Accrediting Environmental Laboratories.

The purpose of laboratory accreditation is to instill public and regulatory confidence in the laboratory data produced and reported to various state and federal environmental programs; and to assist in ensuring laboratories generate quality, legally defensible data, consistent with other accredited environmental laboratories throughout the country and the world. Laboratory accreditation requires that laboratories’ quality systems, staff, facilities, equipment, test methods, records and reports meet objective and measurable criteria adopted by the NELAP of The NELAC Institute (TNI).

New Analytes Available

In order to meet the needs of laboratories and data users, MNELAP added several new analytes to the list of available analytes for accreditation.  The department reviewed the list of  requested analytes and added Anthanthrene (CAS # 191-26-4), Available Cyanide, Benzo[c]fluorine (CAS# 205-12-9), Cyclopenta[c,d]pyrene (CAS# 27208-37-3), Dibenzo[a,l] pyrene (CAS# 191-30-0), 5-Methylchrysene (3697-24-3), 6-Nitrochrysene (CAS# 7496-02-8) and Residual Range Organics to the list previously published.

Requests to add fields of testing for new analytes in response to this notice of availability, do not require payment if the laboratory holds valid accreditation for the changed test category and applies for additional analytes within the same test category, and the lab applies no later than 180 days after the notice of availability is posted. Please see the official notice in the Minnesota State Register for additional information and details.

USBank Electronic Payment System and your Checking Account

The Environmental Laboratory Data Online (ELDO) system now accepts online electronic payments for laboratory accreditation fees. Electronic checks and savings account payment transfers do not incur a transaction fee.  Paying by electronic transfer is easy and convenient.  Please see the example below:

Method Update Rule (MUR) 2016-Federal Activities

The Environmental Protection Agency (EPA) is proposing changes through the Method Update Rule (MUR). The 2016 MUR includes updates to methods approved for testing under the Clean Water Act (i.e. NPDES permits) and to the procedure for determining the Method Detection Limit (MDL).  The EPA is in the final stages of preparing and promulgating these changes to the regulations; however, the federal regulatory freeze has put the MUR on hold for now.

The MUR and all methods within are not effective until published in the Federal Register. The final rule becomes effective 30 days after publication.  After the MUR becomes effective, MNELAP will work with our state program partners to determine implementation dates for laboratories to gain accreditation for the newer versions of the methods, and to implement the revised MDL procedures.   In the meantime, please continue to follow the current promulgated Clean Water Program (40 CFR Part 136) Laws and Rules and seek out any needed information or training opportunities your laboratory may be interesting in obtaining about the MUR and its implementation in your laboratory.  The EPA maintains a webpage dedicated to the Method Update Rule-2017 and The NELAC Institute (TNI)  offers training materials on the proposed rule changes, approved methods and updated versions of methodology.

2016 TNI Standard Clarification- State Activities
Currently, the 2016 TNI Standard is available for sale on The NELAC Institute (TNI) website. The 2016 Standard is approved as an ANSI standard; however, the National Environmental Laboratory Accreditation Program (NELAP) States has NOT approved the 2016 TNI Standard for use. The 2016 TNI Standard, specifically the Chemistry Testing module (Volume 1 Module 4), is undergoing revision in order to meet the requirements of the NELAP States.  Once the NELAP States approve the revisions, the NELAP States will adopt 2017 TNI Standard.  Your laboratory can start preparing for any required changes found throughout the other module revisions, but MNELAP requires your laboratory to continue to follow the 2009 TNI Standards until officially announcing the 2017 TNI implementation dates and timelines.
