In 1991, the Lackawanna River Corridor Association gathered data on the water chemistry and biological habitats of Leggetts Creek.

Due to the differing age, depth, and water chemistry, the flashes show considerable variation in their plant and animal communities.
33.
The water chemistry is normal except for a relatively high concentration of phosphorus that promotes the growth of planktonic algae.
34.
By contrast to mechanical erosion, FAC involves dissolution of normally poorly soluble oxide by combined electrochemical, water chemistry and mass-transfer phenomena.
35.
Every few days, a worker checks the water chemistry to insure that there are no chlorides or other rust-inducing chemicals present.
36.
Daffodil cichlids cannot handle large water changes very well unless the new water chemistry closely matches the water they are in.
37.
Bacterial mats of green algae are common in the hot springs, the algae environments are segregated by temperature and water chemistry.
38.
To bring them into breeding mode imitate their natural water chemistry and do water changes to gradually change the water temperature.
39.
But Con Edison said it did not need to, perhaps because it paid closer attention to water chemistry, to limit corrosion.
40.
The system is fully automated, and environmental factors, water chemistry and the status of the plants are monitored by automation control.
