Water Quality Nutrient Analysis for Pacific Island Network Monitoring Samples – Water Quality Protocols Pacific Island Network, National Park Service at Hawaiʻi National Park, Hawaiʻi

1.0 BACKGROUND

The National Park Service (NPS), Pacific Island Network (PACN) Inventory and Monitoring Division, conducts long-term water quality monitoring to assess nutrient conditions and ecological trends in freshwater and coastal ecosystems across PACN parks.

PACN collects water samples under established water quality protocols to support resource stewardship, trend analysis, and reporting requirements under the National Parks Omnibus Management Act of 1998. Laboratory analysis is required to quantify nutrient concentrations and maintain continuity of long-term monitoring datasets.

PACN currently has a backlog of stored water samples collected during calendar years 2024 and 2025 that require laboratory analysis to support timely database entry, interpretation, and reporting.

Because these samples must remain frozen or otherwise preserved under strict handling conditions prior to analysis, prior off-island shipment has resulted in sample thawing during transport, increased Government shipping costs, and elevated risk to analytical data quality. To mitigate this documented performance risk and preserve continuity of PACN long-term monitoring datasets, the Government requires laboratory performance on Hawaiʻi Island.

This requirement directly supports scientifically defensible nutrient analyses used by park managers to assess ecosystem health, identify nutrient enrichment or pollution concerns, and meet monitoring responsibilities under the National Parks Omnibus Management Act of 1998.

Background reference materials include PACN water quality protocols, sample chain-of-custody documentation, and PACN’s standard electronic data template.

2.0 SCOPE

The contractor shall provide all labor, materials, supplies, equipment, quality assurance procedures, and data management necessary to perform nutrient analysis of Government-furnished water samples.

The contractor’s primary analytical laboratory shall be physically located on Hawaiʻi Island.

This geographic requirement is necessary to:

• minimize transport time between PACN sample storage and laboratory receipt

• preserve frozen sample integrity

• reduce risk of thawing or degradation

• maintain scientifically defensible analytical quality

The contractor shall analyze stored water samples for required nutrient parameters, maintain chain-of-custody integrity, implement laboratory quality assurance and quality control (QA/QC) standards, and provide validated analytical results in a Government-specified Microsoft Excel format.

3.0 OBJECTIVES

The objectives of this contract are to:

• Analyze backlog water samples collected during 2024 and 2025

• Quantify nutrient concentrations for required parameters

• Ensure laboratory processing is completed within the period of performance

• Produce high-quality defensible analytical results

• Support PACN long-term monitoring datasets and trend assessments

• Provide data suitable for entry into the PACN water quality database

• Support park resource management decisions regarding nutrient enrichment and ecosystem condition.

4.0 TASKS/ DELIVERABLES

The contractor shall perform the following tasks:

1. Sample Receipt and Chain of Custody The contractor shall coordinate with PACN staff for transfer of water samples and associated chain-of-custody records. The contractor shall:

a. Verify sample receipt

b. Document sample condition upon receipt

c. Maintain sample integrity during storage and analysis

d. Notify the Contracting Officer’s Representative (COR) of any compromised samples within 2 business days

2. Laboratory Analysis The contractor shall analyze water samples for the following parameters:

a. Nitrate + Nitrite (NO₃ + NO₂)

b. Total Dissolved Nitrogen (TDN)

c. Total Dissolved Phosphorus (TDP)

d. Total Nitrogen (TN)

e. Total Phosphorus (TP)

Sample quantities are:

• 861 samples for nitrate + nitrite

• 861 samples for TDN and TDP

• 45 samples for TN and TP

The contractor shall use scientifically accepted analytical methods appropriate for freshwater and coastal nutrient analyses.

3. Quality Assurance / Quality Control

The contractor shall implement laboratory QA/QC procedures sufficient to ensure accurate, repeatable, and scientifically defensible results.

At a minimum, QA/QC procedures shall include:

a. Method blanks

b. Laboratory duplicates

c. Calibration standards

d. Detection limits

e. Documentation of any qualified or flagged results

f. Documentation of analytical anomalies or deviations

The contractor shall maintain records sufficient to support data validation.

4. Data Delivery

The contractor shall provide analytical results in Microsoft Excel format using the Government’s standard PACN data template.

The spreadsheet shall include:

a. Sample identification number

b. Analysis date

c. Parameter name

d. Reported concentration

e. Units

f. Detection limits

g. QA/QC qualifiers

h. Notes regarding data quality issues

5. Communication The contractor shall communicate with PACN staff regarding:

a. Sample receipt confirmation

b. Analytical progress

c. Data quality concerns

d. Any delays affecting delivery schedule

5.0 DELIVERY

The contractor shall deliver all final analytical data electronically to the PACN Contracting Officer’s Representative. Final Excel spreadsheet of all nutrient analyses is due no later than March 31, 2027.

Partial data deliveries may be submitted on a rolling basis as batches are completed.

Electronic delivery shall be via Government-approved email.

6.0 GOVERNMENT-FURNISHED PROPERTY/SERVICE

The PACN Contracting Officer’s Representative will coordinate pickup/delivery logistics 10 after receipt of award.

The Government will provide:

• Stored water samples

• Sample identification information

• Chain-of-custody documentation

• PACN standard Excel data template

• Technical point of contact for sample coordination

7.0 SECURITY& ACCESS REQUIREMENTS:

No special security clearance is required.

Contractor personnel shall protect all Government data associated with sample identifiers and shall not distribute analytical results outside authorized contract personnel.

8.0 PLACE OF PERFORMANCE

All work shall be performed at the contractor’s laboratory facility located on Hawaiʻi Island, State of Hawaiʻi.

No off-island subcontracted laboratory analysis is permitted without prior written approval of the Contracting Officer.
