Point Source Pollution
No specific area.
Superfund Sites
Jet Propulsion Laboratory (JPL) in Pasadena, borderline La Cañada. A 176 acre site. Contamination at the site include 35 seepage pits where liquid and solid wastes were reportedly disposed of. A settling chamber in the JPL storm drain system, contaminated soil excavated from part of that system, and an area where waste solvents were dumped into three separate holes.
Hazardous substances located at JPL include:
waste solvents
solid rocket fuel propellants
cooling tower chemicals
sulfuric acid
freon
mercury
chemical laboratory wastes
"In 1990, JPL detected significantly elevated levels of contaminants in the groundwater underneath and down-gradient of the site. Due to volatile organic compound (VOC) contamination in the groundwater, four municipal wells were shut down between 1989 and 1990 and two Lincoln Avenue Water Company wells were shut down in 1987. NASA installed treatment systems, and municipal wells began operating again in October of 1990. The Lincoln Avenue Water Company also has installed a treatment system on its wells, which are again operational. Approximately 120,840 people live within 4 miles of the site; an estimated 68,000 people obtain drinking water from municipal wells within 4 miles of the site. The Pasadena wells were shut down again in 2001 because of perchlorate (a component of solid rocket fuel) contamination. The perchlorate plume reached the Lincoln Avenue wells at levels above the State of California standards in 2004 and NASA paid for the installation of an ion-exchange/carbon filter treatment system."

Air Quality
Air Quality in Pasadena and Altadena are at safe levels for people. As the day progresses those who are sensitive may have trouble as the smog comes in though the day.
Range is 0 - 500
Nitrogen Dioxide is at a good level of 30
Ozone is at a good level of 25
Carbon Monoxide is at a safe level of 15
