The one- to four-page fact sheets will be assembled into a two-pocket folder entitled Private Well Owners Guide. The titles will also be a part of the Changing Rural Landscapes project whose goal is to educate exurban, small acreage residents. The authors have made every effort to align the fact sheets with the proposed Arizona Cooperative Extension booklet An Arizona Well Owners Guide to Water Sources, Quality, Sources, Testing, Treatment, and Well Maintenance by Artiola and Uhlman. The private well owner project was funded by both the University of Arizonas Water Sustainability Program-Technology and Research Initiative Fund and the USDA-CSREES Region 9 Water Quality Program.

Paviršinio vandens telkinio kokybė yra viena iš svarbiausių aplinkosauginių problemų Lietuvoje, kuri priklauso nuo į vandens telkinius patenkančių teršalų. Tyrimo objektas: Ventos upės vandens taršos kontrolė atliekant DUFI testą bei įvertinant pakrančių apsaugos zonas. Magistro darbo tikslas: Nustatyti Ventos upės vandens kokybę taikant bestuburių organizmų testą DUFI metodu, bei įvertinti pakrančių apsaugos zonas ir apsaugos juostas tiriamoje teritorijoje. Magistro darbo uždaviniai: 1. Nustatyti makrozoobentoso rūšinę įvairovę Ventos upėje Kelmės raj. 2. Atlikti Ventos upės būklės vertinimą pagal makrozoobentosą DUFI metodu. 3. Įvertinti apsaugos zonų ir apsaugos juostų atitikimą teisiniams dokumentams tirtose Ventos upės vietose. 4. Įvertinti Ventos upės vandens kokybę pagal gautus rezultatus atlikus DUFI testą ir įvertinus pakrančių zonas. 5. Pateikti rekomendacijas Ventos upės vandens kokybei užtikrinti. Tyrimai atlikti 2013 metais gegužės–spalio mėnesiais taikant bestuburių organizmų testą DUFI metodu, kurio metu nustatyta ir įvertinta Ventos upės vandens kokybė pasirinktose tyrimo vietose upei tekant Kelmės rajono teritorijoje. Tyrimo metu buvo paimta 12 mėginių. Mėginiai spyrio metodu, kurio metu išjudintas gruntas kartu su gyvūnais patenka į pasroviui laikomą tinklelį, iš kurio po to kruopščiai jie išrūšiuoti į plastmasinius indelius. Sudarytas makrozoobentoso mėginys gabentas į patalpą, kur identifikuoti surinkti mėginio organizmai iki genties. Iš aplinkos į...

The object: The water pollution control in Venta River by DUFI test and assessment coastal protection zones. The aim: Determinate water quality in the Venta River using invertebrate organisms DUFI test method and to assess coastal protection zones in the target area. Master tasks: 1. Set macrozoobenthos species diversity in the Venta River of Kelme district. 2. To perform condition assessment in Venta river by macrozoobenthos DUFI method. 3. Assess protection zones and protection strips compliance with legal documents studied in Venta places. 4. Assess water quality in Venta River according to the results after the DUFI test and evaluation coastal zones. 5. To adduce recommendations water quality guarantee of the Venta River. Studies were caried out in 2013 May – October using invertebrate organisms test DUFI method, which identified and assessed water quality of the Venta River in selected study areas of the river flowing Kelme district area. Study was taken 12 samples. Samples kick method, which rocked the soil together with the animals enter the stream stored in the grid, from which they are then thoroughly sorted into plastic cups. Sample consists of macrozoobenthos was carried in to the room, where the identification collected of organisms sample to the tribe. From the environment to the falling water pollution traps the...
