EVALUATION OF THE EFFECTS OF LABORATORY FILTERING ON SAMPLE 

ACTIVITY

Influent and effluent samples collected from CWT, ZLD, POTW-I wastewater treatment 

facilities, and produced water from well sites were analyzed both pre- and post-filtering (samples 

are hereafter referred to as "unfiltered," and "filtered,” respectively). The filtering was only 

performed in the laboratory, and no samples were filtered prior to reaching the laboratory. Each

pair of unfiltered/filtered results were then compared and evaluated to determine what effects, if 

any, filtering may have had on the activity. The following hierarchy was used to break down this 

comparison study:

 Facility type (CWT, ZLD, POTW-I, and Production),

 Sample type (influent or effluent; note that produced water only had one sample type), and

 Target analyte/nuclide (including: gross , gross , Ra-226, and Ra-228).

This hierarchy yielded 27 unique target analyte groups in total. Each of the 27 groups were 

evaluated by considering the following metrics:

 Only detected data were considered for this evaluation. If one or both of the 

unfiltered/filtered pair had a non-detect (result less than MDC), then that sample pair was not 

included in the evaluation.

 The results from each unfiltered/filtered pair were checked for consistency by evaluating 

whether the error bars from the pair overlapped. If the error bars did overlap, the pair was 

said to be “consistent”; if the error bars did not overlap, the pair was said the be “discrepant.”

 Each unfiltered/filtered pair was then evaluated by performing a relative percent difference 

(RPD) calculation. If the RPD was less than 35 percent, the pair was thought of as having 

passed a duplicate test for consistency; if the results were greater than 35 percent, the pair 

was thought of as having failed the duplicate check, which may indicate that the results are 

discrepant.

 Each unfiltered/filtered pair was then evaluated by performing a duplicate error ratio (DER).

If the DER was less than 1.42, the pair was thought of as having passed a duplicate test for 

consistency; if the results were greater than 1.42, the pair was thought of as having failed the 

duplicate check, which may indicate that the results are discrepant.

 Each unfiltered/filtered pair was also evaluated to determine which sample had the higher 

activity. A finding that either the filtered or the unfiltered results exclusively or consistently 

had the higher activity would allow the conclusion that filtered had some effect. A finding 

that there was a mix of both filtered and unfiltered results that had higher activity indicated 

that there was no appreciable effect that filtering had on the samples.

 Finally, for each unfiltered/filtered pair, each of the four analytes were reviewed against the 

above criteria to determine whether there was a sample-specific correlation of the results. 

For example, if gross  and gross  were discrepant for a given sample pair, each of the 

remaining nuclides for that sample pair were checked to see if they were discrepant. A 

sample pair that was discrepant across all analytes would be considered a strong indication 

that filtering had some effect on that specific sample pair. If the results yielded a mix of 

discrepant and consistent results across all analytes, then the conclusion may be that filtering 

had no discernible effect.

Results

Table I-1 is generally representative of the outcome of the evaluation that was observed in all 

sample groups (i.e., across all facilities and analytes).

Discussion

Using Table I-1 as an example, the evaluation leading to a conclusion is as follows:

 There were nine pairs usable for the evaluation.

 Of the nine pairs of usable data, there were three pairs of results that were consistent and six

pairs of results that were discrepant.

 Of the six discrepant pairs, there were four pairs in which the filtered result was higher than 

the unfiltered results, and two pairs in which the unfiltered result was higher than the filtered 

result.

The conclusion from this evaluation is that there is no apparent trend or bias that filtering 

produces. This same evaluation was performed for each sample group and the conclusions are 

presented in Table I-2.

The conclusions fall into the following categories:

 NC (No Conclusion) – indicates that there were too few data points to make a conclusion. 

 NE (No Effect) – indicates that there appears to be no consistent effect that filtered had on 

sample results.

 UBH (Unfiltered Biased High) – indicates that although there was a mix of data, there are 

significantly more unfiltered results that were higher than their unfiltered counterparts.

 FBH (Filtered Biased High) – indicates that although there was a mix of data, there are 

significantly more filtered results that are higher than their unfiltered counterparts.

 UCH (Unfiltered Correlates High) – indicates that there appears to be a correlation between 

unfiltered results and greater activity.

 FCH (Filtered Correlates High) – indicates that there appears to be a correlation between 

filtered results and greater activity.

There was no correlation found within any sample group. For the most part, there was either not 

enough data to evaluate or the data appeared to be mainly consistent with a distribution of results 

around the consistency.

There were some indications that either the unfiltered results or the filtered results may have 

been biased higher. However, across different sample groups this bias was not maintained for 

any analyte.

The totals serve to provide a general synopsis of all the data. Sixty-seven percent of the data 

pairs exhibit results that are consistent between the filtered and unfiltered analyses. Of the 

remaining data, 20 percent of the pairs had unfiltered data that were more elevated than their 
PA DEP TENORM Study Report – Appendix I Rev. 0

January 2015 I-3

filtered counterpart, whereas only 13 percent of the pairs contained filtered results that were 

higher.

Overall, the data seem to indicate that filtering may have a very small, if not negligible, effect.

Considering that this effect, if it exists, resulted in a meaningful distribution of both sample 

activity increases and decreases, it is likely nuclide-specific and/or facility-specific.

One final analysis was performed on the data which looked at all the results for a given sample 

pair to determine whether the effects of filtering were consistent for a given sample across all 

analytes. The results of this evaluation were inconclusive at best, indicating once again the 

filtering may have no consistently recognizable effect.

Notes: All results in units of pCi/L.

Conclusion based on detected results only, by evaluating the four comparison metrics presented.

MDC denotes Minimum Detectable Activity.

RPD denotes Relative Percent Difference (values less than 35% are potentially identical).

DER denotes Duplicate Error Ratio (values less than 1.42 are potentially identical).
