01Acute aquatic toxicity · 2010
Bio-Aquatic Testing, Inc.
48- and 96-hour tests under an EPA protocol
The laboratory evaluated the product, No. 2 fuel oil and their mixture using Americamysis bahia and Menidia beryllina.
LC50 · 548.66 / 703.43 ppmReported findingFor the product alone, the report recorded LC50 values of 703.43 ppm at 48 hours and 548.66 ppm at 96 hours. In the same test, No. 2 fuel oil recorded 2.24 and 2.51 ppm, respectively.
Scope and limitationA higher LC50 value represents lower acute toxicity within this test. It does not mean zero toxicity or authorize an environmental discharge.
02Crude-contaminated water
CIQA · Centro de Investigación en Química Aplicada
Controlled treatment of fresh and saline water
The study used simulated water containing 1,500 ppm of API 25 crude, different doses, ambient temperature and 80 °C, with monitoring for up to 240 hours.
83% · 66%Reported findingIn the series treatment at 80 °C, the report recorded an 83% reduction in fresh water and 66% in saline water after 240 hours.
Scope and limitationReported residuals were 184 and 368 ppm; the study itself notes that they did not reach the 15 ppm reference limit. Results depend on dose, temperature and time.
03Independent analysis
Alamo Analytical Laboratories, Ltd.
Hydrocarbon quantification in treated samples
Analytical laboratory report for reviewing hydrocarbon presence in the evaluated matrices after treatment.
TPH · laboratorioReported findingThe document provides sample results and methodology for independent technical review.
Scope and limitationResults must be interpreted with the matrix, sample preparation, analytical method and chain of custody in the original report.
04Drilling cuttings
Dynatec Labs · El Paso, Texas
Analytical monitoring of the washing process
Laboratory report associated with drilling-cuttings washing and monitoring of hydrocarbon content.
Recortes · TPHReported findingThe report enables review of results within the evaluated sample and protocol.
Scope and limitationIt should not be extrapolated to another cutting type, crude, concentration or process without a specific test.
