Resource Concern Thresholds

AQRV Type: WATER
Sensitive Receptor Sensitive Receptor Indicator Thresholds
Perennial Streams Acid Neutralizing Capacity In perennial streams, no more than .1 microequivalent/liter measurable decrease in acid neutralizaing capacity is acceptable
Perennial Streams Chronic Acid Neutralizing Capacity To maintain healthy biological functioning in perennial streams, the chronic acid neutralizing capacity must be >= 25 ueq/l.
Perennial Streams Chronic pH To maintain healthy biological functioning, the chronic pH of perennial streams must be >= 6.0.
Perennial Streams Episodic Acid Neutralizing Capacity To maintain healthy biological functioning in perennial streams, the episodic acid neutralizing capacity must be >= 0 ueq/l.
Perennial Streams Episodic pH To maintain healthy biological functioning, the episodic pH of perennial streams must be >= 5.5.
Perennial Streams pH In perennial streams, no more than .01 measurable decrease in pH is acceptable

Pollutant Exposure Concern Thresholds

Pollutant Exposures Level Name Thresholds
Nitrogen DEPOSITION Nitrogen deposition may be expected to cause cation leaching in soils when N levels are greater than 12 kg/ha/yr. Below 5 kg/ha/yr, negative effects to soil and vegetation are not expected
Ozone W126 Biomass reduction of ozone sensitive species may occur when the W126 ozone metric (for April-September) is > 14.5 ppm-hours. This should be evaluated in conjunction with the N100 value.
Ozone N100 METRIC Biomass reduction of ozone sensitive species may occur when the number of hours from APRIL-SEPTEMBER with an ozone concentration greater than or equal to 0.100ppm equals or exceeds 4. This should be evaluated in conjunction with the W126 value.
Sulfur DEPOSITION Sulfur deposition may be expected to cause cation leaching and increased aluminum toxicity in soils when levels are greater than 20 kg/ha/yr. At 5 kg/ha/yr or below, sulfur negative effects to soil and vegetation are not expected.
