Grayson Lake, KY NATTS Network Assessment Review
• Established 2008: Carbonyls, Chromium VI, PAHs, PMio Metals, and VOCs
o Chromium VI ended in in 2013
• For the NATTS Network Assessment (2008-2018):
o 17 of 18 Method Quality Objective (MQO) Core HAPs were included in the national trends
¦ Chromium VI: Did not have six consecutive years of datasets suitable for trends analysis,
o 160 of 174 pollutant datasets were suitable for trends analysis
o Annual Average and 3-Year Rolling Average Concentrations were generally flat over time, with the
exception of a few pollutants,
o 100% Reporting of Datasets
• Method Quality Objectives (MQO): 2008-2018
o Completeness: Met 85% completeness in 166 of 192 pollutant datasets
o Method Detection Limits: Met MDL Target Ratio of 1.00 in 182 of 204 pollutant datasets
o Bias: Met ±25% for 145 of 155 pollutant datasets
o Overall Method Precision: Met <15% CV for 66 of 110 pollutant datasets
o Analytical Method Precision: Met <15% CV for 110 of 124 pollutant datasets

National Summary: NATTS data were collected at 27 locations across the United States,

Datasets by Pollutant Group
with sites beginning in 2003 or later (Figure 1) for 19 core HAPs. Over 528,000 concentrations

Due to site logistical issues, sampling ended at the Hazard, KY site in May 2008. The site relocated to Grayson Lake, KY and sampling resumed in October 2008.
b: Scheduled sampling ended midway through the year, thus, the site did not have the opportunity to collect enough samples to meet the 85% MQO.
c: Pollutant was expected, but results were invalidated at this site for this year.
d: Analysis of VOCs were switched to the National Monitoring Program lab in summer 2010.
