percolation and evaporation pond operation accepting oilfield produced water, which is a highly saline byproduct of local oil production that contains small concentrations of cancer-causing chemicals.

The wastewater allegedly contained arsenic, benzene, ethylbenzene, naphthalene, radionuclides and toluene.Clean Water Fund and AIR alleged the practice has created an underground plume that has spread more than two miles since monitoring wells were established in the area in 2004, and that the contamination may eventually reach Buttonwillow's drinking water supply.

Valley Water Management Company (owner) & Sentinel Peak Resources (oil producer): fined $645,000

Clean Water Fund & Association of Irritated Residents: sued using Prop 65 (Safe Drinking Water and Toxic Enforcement Act of 1986) to shut down pond

other oil companies: inject wastewater deep underground in or near reservoirs where it originated

Central Valley Regional Water Quality Control Board: forced closure of pond out of concern that underground plume will reach Kern River and Bakersfield's drinking water

Smart autoalarm guardrail is designed for helpping people emergency contact and remind the other drivers when car accident happen in remote area. People will drive on some remote area, or late night. If car accident happens, might be no one know the accident is happen. This design is help the litigant automatically make a emergency call, and send the location through the GPS when the car is crash the guardrail. As well as, it can turn on/flash the light within the accident area to warn the other drivers. 

Smart guardrail is concept design by Yuguo chen and Changlin He, who are from School of Design, Hunan University in China. 

This design could help people in an unknow emergency situation, for example, the driver pass out when the traffic accident happen, and this design can help people to save life. However, I think this concept design might be cost a lot if it is applied into real life, because it means there are lots of guardrail need to install this system, and the government also need to prepare another extra fee for repair the guardrail after every accident. 

The smart guardrail is designed to be used in some remote area and highway. 

Smart Guardrail is autoalrm and could be send location to the nearset emergency centre by GPS when the car crash into the guardrail. As well as the warning light within the area will be swithched on to avoid the potential sencond accident. The system is design to install into the highway guardrail, and use the circuit to make the system work. Therefore, the materials might be include electrical wire and circuit, and also plastic caution lights.

This concept design is supposed to install on the highway guardrail and work automatically in a pubilc area, therefore there is no specifically skill need to learn. 

Smart Guardrail is considered as a good concept design, because it can be solve the emergency problem for traffic accident in some situation. This design is applied a common materials and method to solve problem. It is a small change and might make a big influenced. But the design could be used or not is depend on the cost would be proportional to the value or not.

This concept design is create a market which is within more functions and technologies for guardrail. In the existing market, there are some good design highway guardrail, such as EZY-guard smart guardrail. Most of the existing product are applied outter shapes and physical structures rather than some electrical technology. Compare to the existing products, this concept design is more challenged by the cost.
