the migration of contamination. A site-specific permeable reactive barrier design (along<br />
with some field work) will be completed for Mortandad Canyon in FY02.<br />
The project design indicates that LANL’s steep, confined canyons are ideal for using<br />
permeable reactive technologies. However, as these barriers are constructed, they will<br />
be evaluated for effectiveness in controlling contaminants, and a range of possible<br />
measures will continue to be considered to meet contaminant control objectives.<br />
Benefits of controlling the spread of elevated contamination include<br />
• reduced characterization and analysis costs (reduced effort of “proving”<br />
monitored natural attenuation will be sufficient in a highly complex<br />
hydrogeologic setting);<br />
• reduced risk and perceived risk, through a proactive measure to address a major<br />
regulatory and public concern; and<br />
• stimulating endpoint focus for groundwater by implementing the first steps in a<br />
graded approach.<br />
Monitoring<br />
Groundwater monitoring is a key element of the EM end-state for groundwater at LANL.<br />
Monitoring and monitored natural attenuation are expected to be the primary elements<br />
of the remedies for most contaminated groundwater locations at LANL. A substantial<br />
amount of groundwater monitoring is expected in the LTES program for LANL.<br />
Table 4-1 summarizes the groundwater monitoring requirements that are applicable at<br />
LANL.<br />
