Diamond Bar CA still carries the name of the branding symbol (a diamond over a bar) registered by one of the area’s early cattle ranchers, but everything else in the city is thoroughly modern. It even has the first hydrogen fueling station ever built in southern California. The fueling station is located near the facilities of one of the biggest employers in Diamond Bar CA, the South Coast Air Quality Management District. The AQMD is responsible for setting and enforcing standards designed to clear up smog and air pollution problems in southern California. When it comes to clearing up air quality issues and health hazards in your own home, you need to take the initiative. AQHI Inc. can help. We can safely remove asbestos, lead, PCBs, and mold from your property through our expert environmental remediation services. Once these contaminants have been removed, your home will be safer and your resale value should increase.
