ýj. -'ýThis set of NOAA Screening Quick Reference Tables, or SQuiRTs, presents screening concentrations for inorganic and organic contaminants in various environmental media. Guidelines.fdr sample preservation and options for laboratory analytical techniques are also included.The SQuiRT cards were developed for internal use by. the Coastal Protection

& Restoration Division (CPR) of NOAA. The CPR Division identifies potential impacts to coastal resources and habitats likely to be affected by hazardous waste sites. To initially identify substances which may threaten resources of concern to NOAA, environmental concentrations are compared to these screening levels. These tables are intended for preliminary screening purposes only: they do not represent official NOAA policy and do not constitute criteria or clean-up levels.NOAA does not endorse their use for any other purposes.

Screening levels are reported with the number of significant figures they were originally reported with.Further guidance on the recommended application of various screening guidelines is provided in the supporting source documentation (listed on the last page of each section).

Users of the SQuiRT cards are strongly encouraged to review supporting documentation to determine appropriateness for their specific use.The SQuiRT card set is organized into the following sections:* Inorganics in Solids (fi'eshwater and marine sediment, plus soil)* Inorganics in Water (groundwater and surface water)' Organics in Water and Solids" Analytical Methods for Inorganics" Analytical Methods for Organics" Guidelines for Sample Collection

& Storage For surface water samples, the CPR Division compares measured contaminant concentrations to their applicable, EPA Ambient Water Quality Criteria (AWQC) for the protection .of aquatic organisms.

Because releases from hazardous waste sites are often continuous and long-term, concentrations are compared directly with the chronic AWQC, when available.

SQuiRTs for trace element AWQCs have been updated to show values for just filtered samples, as well as the formulae to calculate exact criteria for elements whose criteria are hardness-dependent.

Groundwater concentrations are also screened against AWQC. However, given the dilution expected during migration and upon discharge of groundwater to surface water, CPRD uses 10 times the applicable AWQC for screening.

If available, suitable site-specific dilution factors are used. Maximum Contaminant Levels (MCLs), applicable to drinking water sources and secondary MCLs applicable to groundwater, are also provided on the SQuiRT cards.Promulgated criteria similar to the AWQC are generally not available for contaminated soils or sediments.

For screening purposes, inorganic contaminant levels in soils are compared to the average concentrations found in natural soils of the United States. Organic compounds in soil are screened against risk-based Canadian.

soil standards.

Soil standards for different land use categories are listed to provide perspective.

Soil values are not used by NOAA to estimate aquatic exposures.

NOAA screens soil concentrations only to estimate which contaminants may be elevated and thus represent potential contaminant sources to aquatic habitats of concern.Multiple sediment screening values have been included in the NOAA SQuiRTs to help portray the entire spectrum of concentrations which have been associated with various probabilities of adverse biological effects. This spectrum ranges from presumably non-toxic, e.g., trace metal levels reported to represent non-anthropogenically 50 values in ppb dry weight)Predicted Toxicity Gradient: These tables were developed for internal use for screening purposes only: they do not represent official NOAA policy and do not constitute criteria or clean-up levels.hen ade o ensue accuracv owever, NOAA is not Iable for e rrors.

The values shown on page 3 assume 100 mg/L. Values for a.different hardness may be calculated using the above equations to arrive at a CMC or CCC for filtered samples. Hardness may range up to 400 mg/L as calcium carbonate.

For hardness above this range, use 400 mg/L as the maximum value allowed.Criteria for most metals are expressed as standards for samples filtered through 0.45 pm filter (i.e., "dissolved").

To convert unfiltered concentrations to filtered, multiply the unfiltered concentration value by the appropriate Conversion Factor (CF) above. For cadmium and lead, the conversion factor itself is hardness-dependent.

For salinity between 1 and 10 ppt, use the more stringent of either fresh or marine values.CMC -Criteria Maximum Concentration is the highest level for a 1-hour average exposure not to be exceeded more than once every three years, and is synonymous with "acute."

7063 is ASV; where available, soil detection limits in ppm are in parentheses.

Except as noted, most individual procedures are proposed to be integrated into Method 7000B or 7010.All method numbers refer to EPA SW-846, Volume IIl with changes as proposed for Volume IV.ICP's advantage is that it allows simultaneous or rapid sequential determination of many elements, but suffers from interferences.

AA determinations are normally completed as single element analyses.

ICP and Flame AA have comparable detection limits (within a factor of4), but ICP-MS (6020A) can drastically improve the detection limitis (e.g., an order of magnitude lower). Furnace AA generally exhibits lowerdetection limits than ICP or Flame-AA.

and offers more control over tunwanted matrix cotnponents.

X-RAY and imonuroassavs allow field determinations.

Screening with conservative, lower-threshold values (e.g., TELs) ensures, with a high degree of confidence, that any contaminant sources eliminated from future considerationi pose no potential threat. Conversely, it does not necessarily predict toxicity.

Upper thresholds(e.g., PELs) identify compounds which are more probably elevated to toxic levels.Sediment quality benchmarks have been derived in a variety of ways for varying predictive goals. They are not interchangeable.

Nor should they be applied without a reasonable understanding of their development, their perfornance, and their limitations.

For sediment-associated contaminants, dry weight concentrations are screened against published sediment quality benchmarks.

Some benchmarks are available only on a TOC nornalized basis, and are footnoted as such. Separate values are provided for either freshwater or estuarine and marine sediments.

The Effects Range-Low (ERLs) and Effects Range-Median (ERMs) plus the marine Threshold Effects Levels (TELs) and Probable Effects Levels (PELs) are based upon a similar data compilations, but use different calculations.

The ERL is calculated as the lower 1 0 th percentile concentration of the available sediment toxicity data which has been screened for only those samples which were identified as toxic by original investigators.

It is not an LCi0. Since the ERL is at the low end of a range of levels at which effects were observed in the studies compiled, it represents the value at which toxicity may begin to be observed in sensitive species. The ERM is simply. the median concentration of the compilation of just toxic samples. It is not an LC50.The TEL is calculated as the geometric mean of the 1 5 th percentile concentration of the toxic effects data set and the median of the no-effect data set; as such, it represents the concentration below which adverse effects are expected to occur only rarely. The PEL, as the geometric mean of the 50% of impacted, toxic samples and the 85% of the non-impacted samples, 'is the level above which adverse effects are frequently expected.

Freshwater TEL/PELs are based on benthic community metrics and toxicity tests results.Apparent Effect Thresholds (AETs) relate chemical concentrations in sediments to, synoptic biological indicators of injury (i.e., sediment bioassays or diminished benthic infaunal abundance).

Individual AETs are essentially-equivalent to the concentration observed in the highest non-toxic sample. As such, they represent the concentration above which adverse biological impacts would always be expected by that biological indicator due to exposure to that contaminant alone.Conversely, adverse impacts are known to occur at levels below the AET. Only the lowest of the potential AETs is listed. AET values were developed for use in Puget Sound (Washington) and are not easily compared directly to other benchmarks based on single-chemical models and broader data sources. SQuiRT cards have been updated with interim AET values which are subect to change.For freshwater sediments, the Upper Effects Threshold (UET) was derived by NOAA as the lowest AET from a compilation of endpoint analogous to the marine AET endpoints.

The UETs for organic contaminants are generally listed for a sediment containing 1% TOC.Every effort has been made to ensure accuracy in these SQuiRT cards.However, NOAA is not liable for errors in transcription, in the original sources, or revision of values. These screening values are subject to change as new data become available.
