THE BORDER LAND
IMPACT ASSESSMENT OF VALLE DE JUAREZ
•First phase performed in 2008-2009 • Baseline conditions through epidemiological survey, sampling and analysis of
drinking water, wastewater, human feces, and soil. • Educational outreach.
•Second phase, funded by Border 2012, from September 2012 to date • Multi-institutional team approach: PAHO, BECC, UACJ, University of Texas,
COLEF, AQUA XXI. • Revisit communities and perform epidemiological survey (not an IA
requirement) and questionnaire on use of constructed water/wastewater facilities as indicated in the IA methodology.
• Interview local authorities as to the condition / operation of the new
water/wastewater infrastructure. • Sampling and analysis of the same media as in phase one.
Statistics, to date …
• 278 survey questionnaires applied in 10 communities (160 applied in 5 communities with BECC/NADB projects)
• 36 interviews with local officers (in synthesis process)
• 79 samples collected to determine 27 physical-chemical and 6
microbiological parameters (2,607 lab analysis performed)

CASE STUDY: VALLE DE JUAREZ
Impact Assessment Indicators
Remarks: • The number of
agriculture workers increased in the last 2 years • The % of households
connected to the sewer, households with plumbing inside, and continuity of service are maintained, despite the population increase. • The % of households
giving additional treatment to the drinking water continued to fall steadily.

FINAL REMARKS
• PRTR instrumental in accounting for lead – the lead
is not staying in town;
• PRTR platform is friendly and practical, however is
unreliable at a city level because of possible bad
registries;
• Pollution transfer indicators could be developed if
QA/QC algorithms are introduced to identify
possible outlier registries.
