These values were taken <br />from Table IV, CDOH Reg. 31, using a mean hardness of 400 mg/l. All <br />acute/chronic values are the 'dissolved' form. <br />A = Detection limit is 0.05 mg/l. All values above detection limit are <br />compared to table standards found on this website: <br />http://www.epa.gov/waterscience/criteria/ammonia/99update.pdf <br />B = Detection limit for stream and spring sites is 0.2 ug/l. <br />C = Standard is 0.002 mg/l (un-ionized). Detection limit is 0.02 mg/l.
