WHY DOES DEC MONI TOR ACI D RAI N?

STATE ACID DEPOSITION CONTROL ACT (SADCA) MANDATE
INCREASED SPATIAL ACID RAIN MONITORING COVERAGE

ACROSS THE STATE ESPECIALLY IN ECOLOGICALLY SENSITIVE REGIONS, SUCH AS THE ADIRONDACKS.

MORE THAN HALF OF DEC ACID RAIN SITES MONITOR OTHER

POLLUTANTS INCLUDING SO2, O3, PM2.5 AND METEOROLOGICAL PARAMETERS.

DEC MONITORS ARE LOCATED IN SUBURBAN, URBAN AND

RURAL AREAS.
