| Abstract/Contents: | "Concern over declining water quality in suburban and urban watersheds has heightened awareness and speculation over the sources of pollution. Water in these developed areas can contain organic and inorganic compounds including pesticides, nutrients, and hydrocarbons. A comparison of agricultural and suburban watersheds shows urban streams and groundwater having higher concentrations and more frequent detection of total phosphorus (P) often exceeding regulatory levels, insecticides (diazinon, carbaryl, chlorpyrifos, and malathion), herbicides (atrazine, simazine, and prometon), volatile organic compounds (90 percent of samples), and trace elements, such as cadmium, lead, zinc, and mercury. Newly released pesticides also have been found in surface water. The specific source of these materials from urban areas has not yet been investigated. In contrast, nitrogen (N) is often found at much higher concentrations in agricultural areas than in manage turfgrass sites. The average N concentration in shallow groundwater monitoring wells was 2 to 3 times higher in row crop agriculture than residential properties or golf courses. Small-scale research results confirm turfgrass has lower losses of N to groundwater than other land uses including ornamental plantings. It is unclear as to the source of elevated P concentrations observed in urban/suburban surface water in the USA is. There is considerable speculation that managed turfgrass sites are the source of P in surface water, but the research does not justify this claim. Other land uses, storm water management practices, and an abundance of impervious surfaces in urban/suburban watersheds can in many cases contribute as much if not more P to surface water. In comparative studies, high-density turfgrass often has lower runoff and P loss to surface water than other land uses. Unfertilized wooded areas can have high P losses in runoff due to lack of ground over. Road deicing and traction materials often contain high P concentrations, which is directly diverted into the storm water system feeding urban surface water. Turfgrass pesticide fate studies have shown that with correct application and timing, detection in groundwater or shallow leachate sleldom occurs. More frequent detection occurs in surface water samples, particularly from golf course and in watershed scale studies. Despite evidence of deteriorating sururban water quality, there is little research concerning the actual cause, other than overall development itself. More research is needed to determine the source of pollutants in urban/suburban areas. Of interest in this paper is the role of turfgrass in water quality in urban/suburban areas. It is not entirely clear what the role of turfgrass has on these ecosystems, and, as such, requires further research." |
