11. Scientists are testing for nutrients, water chemistry , and phytoplankton levels. 12. Water chemistry of wetlands varies across landscapes and climatic regions.13. Past mining activities and ore-smelting operations continue to influence the water chemistry of the stream. 14. But the characteristics of Linear's breakup suggest it had a different water chemistry , Weaver said. 15. The two arms of the stream display a large and unusual contrast in water chemistry . 16. Salinity has a strong influence on wetland water chemistry , particularly in wetlands along the coast. 17. Fry of this species are particularly sensitive to changes in water chemistry and to elevated temperatures. 18. USGS also maintains a water chemistry monitor at Milltown, Maine ( ) where the rivershed is. 19. They said there has been no change in the water chemistry that could cause the leaks. 20. Their water chemistry varies from alkaline to acidic.
