- Eutrophication
- Natural eutrophication is the process by which lakes gradually age and become more nutrient rich. It normally takes thousands of years to progress. However, humans, through their various cultural activities, have greatly accelerated this process in thousands of lakes around the globe creating nutrient pollution from runoff from agricultural fields, field lots, urban lawns, golf courses, and untreated, or partially-treated, domestic sewage. Sewage was a particular source of phosphorus to lakes when detergents contained large amounts of phosphates. The phosphates acted as water softeners to improve the cleaning action, but they also proved to be powerful stimulants to algal growth when they were washed or flushed into lakes. These "algae blooms" lead to changes the water quality in a lake - bringing oxygen depletion and resultant fish kills. (See BOG)

Firewalls are rated by how long they are expected to hold back a fire on either side of the wall. A 2 hour fire rating requires two layers, and a 3 hour rating requires three layers of type X drywall.

Polybutylene piping Polybutylene is a form of plastic resin that was used extensively in the manufacture of water supply piping from 1978 until 1995. Due to the low cost of the material and ease of installation, Polybutylene piping systems were viewed as "the pipe of the future" and were used as a substitute for traditional copper piping. It is most commonly found in the "Sun Belt" where residential construction was heavy through the 1980's and early-to-mid 90's, but it is also very common in the Mid Atlantic and Northwest Pacific states. |
