Additional Information

Additional Information

When someone buys a property, they hire a consultant to check for any potential liability such as asbestos, underground storage tanks, or any contaminated sites such as superfund sites in the nearby area. This is a quick survey. This is called doing a phase-I survey. If any contamination is found, then samples of soil, ground water, more asbestos, and lead samples are taken. This is called Phase-II. If a contamination is confirmed, the site has to be remediated. This is called phase-III. Typical tests done for Phase I and II are TPH, BTEX, VOC, SVOC, and metals.

The Most Common Tests We Perform

The Most Common Tests We Perform

The most common tests we perform contain approximate ratios by quantity. For example, A & B Labs performs 4 metals by ICP-AES in water for every two metals in soil for every one metal in air.

Miscellaneous Definitions

Total RCRA metals – The total concentration of 8 metals of special concern for disposal. These eight are arsenic (As), barium (Ba), cadmium (Cd), chromium (Cr), lead (Pb), selenium (Se), silver (Ag), and mercury (Hg).

TCLP RCRA metals – Those same 8 metals are analyzed after a special extraction that simulates the changes in a landfill.

TCLP – Toxicity Characteristic Leaching Procedure. This special extraction is meant to simulate the changes in a landfill. After this TCLP extraction, the sample extract can be tested for Volatile Organics, Semivolatile Organics, Pesticides, Herbicides, or the above 8 metals. In this test take 100 grams of the waste and extract in a liquid, acetic acid solution for 18 hrs (overnight) and analyze the extract for 42 components. If any of the components are above the government defined TCLP limit it is classified as hazardous. Sometimes clients may want a TCLP metals analysis done on other metals as well.

Dissolved Metals – A metals analysis performed after the sample has been filtered through a 0.45 micron filter. Filtration must be done before preservation with nitric acid.

TCLP TX335 – This Texas rule applies the USEPA TCLP extraction procedure to 11 metals, plus additional volatiles, semivolatiles, pesticides, herbicides, 8015 (mostly organic alcohols), and 8316 (acrylomide).

Holding Times – These are the maximum allowable times from sample collection to sample analysis for each test. They are determined by USEPA and differ for different matrices. For example, the holding time for Total Suspended Solids (TSS) in water is 7 days. The holding time for semivolatile organics in water is 7 days until extraction and another 40 days until analysis.

Short Holds – A & B Labs defines any analysis with a holding time of less than or equal to 48 hours as a short hold. These analyses must be done very quickly upon arrival so A & B Labs requires them to be given immediately to the analyst. They include turbidity, orthophosphate, nitrite-N, nitrate-N, color, and BOD / CBOD which all have a water holding time of only 48 hours. Coliform bacteria in drinking water is 30 hours. Coliform bacteria and other microbiological parameters have a holding time in wastewater of a measly 6 hours. Hexavalent chromium in water is only 24 hours. Finally many tests in water are meant to be done in the field (such as temperature, pH, DO, and chlorine) and therefore have a holding time of 15 minutes. A complication to always remember is that any test can become a short hold if the client held on to it long enough.

Our standard TAT is 7 business days or later for most tests. For test results needed in less than 7 business days, rush charges may apply. A & B Labs will provide the TAT on each quote.

Rush charges may apply to the tests, if needed and/or specified that the test must be rushed. Rush charges will only apply to those tests in which rushing the sample testing implies an actual cost.

1 BUSINESS DAY TURNAROUND TIME = 100% SURCHARGE (When applicable)
2 BUSINESS DAY TURNAROUND TIME = 75% SURCHARGE (When applicable)
3 BUSINESS DAY TURNAROUND TIME = 50% SURCHARGE (When applicable)
4 BUSINESS DAY TURNAROUND TIME = 25% SURCHARGE (When applicable)
Sample matrix may affect feasible turnaround time

Note for Asbestos: A prep charge fee will be incurred if the samples are prepped but not able to be analyzed due to step rules for overloading. Bulk PLM that requires a separate report and analysis for individual layers will be charged accordingly, per layer.

A & B Labs will pay for the outgoing sample kit shipment costs if the kit order is received 5 business days in advance by using the most cost effective means of shipping available (Examples: UPS Ground Service, FedEx Ground, FedEx Express 3 Day, etc…). For International shipping, the client is responsible for shipping costs both outbound and inbound.

A & B Labs can provide sample media (at cost with a surcharge) provided the laboratory is given at least 5 days notice. Routine kits include PVC filters, MCE filters, sorbent tubes, chain of custody forms and Federal Express return shipment forms with A & B Labs’ ID number. Other media, pumps and related equipment are available for additional charges. All sample media will be charged to the client immediately after the media kit is ordered or given to the client.
