McCampbell - UCMR 5 Testing

EPA UCMR 5 Program

McCampbell Analytical Inc (MAI) is proud to participate in the EPA UCMR 5 program as an approved analytical laboratory that accepts commercial samples for all 30 UCMR 5 contaminants.

UCMR 5 Testing

The United States Environmental Protection Agency published the Fifth Unregulated Contaminant Monitoring Rule (UCMR) in December 2021. This UCMR 5 will require monitoring of public water systems (PWSs) nationwide for 30 contaminants including 29 per- and polyfluoroalkyl substances (PFAS) and lithium using analytical methods and laboratories approved by the EPA for UCMR 5. UCMR 5 will provide new data used to improve the EPA's understanding of the contaminants found in the nation's drinking water systems and at what levels. This data will ensure science-based decision-making and help inform future regulations, infrastructure funding, and remediation needs.

UCMR 5 sampling is scheduled to take place from January 2023 to December 2025. All PWSs serving more than 10,000 people (i.e., large systems) will monitor; all PWSs serving 3,300 to 10,000 people, and 800 randomly selected representative PWSs serving fewer than 3,300 will monitor. PWSs will collect samples for 29 PFAS and lithium. Sample sources include surface water (SW), ground water under the direct influence of surface water (GWUDI), mixed sources (MX) and ground water (GW) systems. As EPA finalizes its sampling design plan for each sample collection year, the Agency will notify the participating small systems.

McCampbell Analytical Inc (MAI) is proud to participate in the EPA UCMR 5 program as an approved analytical laboratory that accepts commercial samples for all 30 UCMR 5 contaminants. MAI has participated in the EPA UCMR program since 2012 including UCMR 3 and UCMR 4 as an approved laboratory accepting commercial samples. MAI has extensive experience in contaminants included in UCRM 5, experience handling the logistics of shipping, scheduling, and budgeting, and experience with UCMR electronic data handling and SDWARS reporting.

UCMR 5 Sample Collection Instructions

General Sample Guidelines

UCMR 5 samples must not be composited (i.e., combined, mixed or blended); samples from each
sampling point must be collected, preserved and processed separately.

Specific sample containers and preservatives are required for each UCMR 5 method. Samples will be
rejected if collected in the incorrect container and will require re-sampling.

PWSs that ship the samples for analysis should ensure that samples are collected early enough in the day to allow adequate time to send these samples for overnight delivery to the laboratory.

The PWS should avoid collecting samples on Thursday and should not collect samples on Friday, Saturday, or Sunday unless special arrangements have been made for the receipt of samples at the laboratory within 48-hours of collection.

If you have any questions, please contact us before sampling at 877-252-9262.

Sample Collection Supplies

Cooler
Sampling Containers
Gloves
Markers
Chain of Custody form
Sample Container Labels
Bagged Ice
Tape for securing the cooler
Optional - Paper Towels for drying the outside of the containers after sampling
Optional - Plastic storage bags for ice or samples

General Sampling Procedure for All Methods:

Use the proper container to collect your sample and do not rinse out any preservatives present.

Wash your hands before and after sampling.

Label sample bottles prior to sampling using a permanent marker. Label should include sample location, date and time collected.

EPA 200.7 Metals - Bottles: 250 mL HDPE plastic (one bottle for each entry point)
EPA 533 PFAs - Bottles: 250 mL PP plastic with screw cap (three bottles for each entry point - Field Blank, duplicate and sample)
EPA 537.1 PFAs - Bottles: 250 mL PP plastic with screw cap (three bottles for each entry point - Field Blank, duplicate and sample)
Two additional bottles are provided for EPA 533 and EPA 537.1 to be collected at a chosen location for Quality Control (MS/MSD) Purposes.

Open the tap and allow the system to flush until the water temperature has stabilized (approximately 3 minutes). Decrease the flow to approximately ¼ inch across (width of a pencil). Collect samples from the flowing system.

Fill sample bottle at an angle pointing away from you. Fill to the shoulder, but do not flush out the preservation reagents. Cap the bottle and agitate by hand until preservative is dissolved. Avoid over filling the bottle to prevent spillage during analysis.

Before submitting your samples to the lab, complete a chain of custody form for each point (EP).

Refrigerate samples or place samples on ice immediately after sampling prior to shipping to lab. Samples must be submitted to the lab within 48 hours of sampling.

Sample Transport and Storage

Samples should arrive at the laboratory packed on ice or with frozen gel packs in a sample bottle constructed of appropriate material as described in the analytical method. Samples that are shipped from the PWS should be sent by priority overnight delivery to the laboratory.

UCMR samples that arrive at the laboratory within 48 hours of collection must not exceed 10ºC.

Samples with water temperatures significantly above 10ºC at the time of collection (e.g., summer sampling events with elevated ambient water temperature), must be iced or refrigerated for a period of time prior to shipping to ensure the laboratory receipt temperature criteria are met.

Samples that arrive at the laboratory on the same day of sample collection (exclusively due to the close proximity of a PWS to the laboratory), may not yet have stabilized to 10ºC or less when they arrive at the lab. These samples are acceptable ONLY if packed on ice or with frozen gel packs immediately after sample collection and hence, delivered while samples are in the process of reaching an equilibrium temperature less than 10ºC. Samples must not be analyzed if they were not shipped properly. Lithium by EPA 200.7 does not have any temperature requirements.
