corrosion is a physic and chemical reaction occurring between a substance and its surrounding environment leading to the change in the substance properties. Corrosion can cause economic damage, loss of life and illness in consumers is watering plants. The aim of this study was to Assessment of scale formation and corrosion of drinking water supplies in Dehloran.
This research was a descriptive and cross-sectional study. the sampling was carried out during one year from 8 wells. Values of Langelier, Ryznar, corrosivity and Puckorius indexes were calculated by using such parameters as total dissolved solids (TDS), calcium hardness, total alkalinity, temperature, pH, pHs on all Sources of drinking water in dehloran.
The results of this study showed that the amount of TDS, turbidity and total hardness wells is lower than the national standard. So that the highest and lowest TDS was obtained for Dashte Akbar 1wells (1084 mg/l) and Bare Bijeh 1(132 mg/l), respectively. As well as The highest and lowest turbidity was obtained for Bare Bijeh 2 wells (0.99 NTU) and Dashte Akbar 1(0.25 NTU), respectively. For all the wells studied was obtained Lanzhylh index between -0.43 to .19, Ryzner of the 7.52 to 9.07, Puckorius index between 8.69 to 11.21 and corrosion of between 8.01 to 8.68, respectively.
The relevant indicators show that drinking water in dehloran corrosive and therefore must be continuously monitored water quality in the distribution network and measures to be applied in the field of corrosion control.

Leishmaniasis is an important parasitic disease in the world. We performed a seroepidemiological study of visceral leishmaniasis (VL) in Dehloran district, Ilam province to determine the seroprevalence of infection among humans and dogs using Direct Agglutination Test (DAT).
In this descriptive analytic study, Sera were collected by a multi-stage randomized cluster sampling from 872 children ≤12 years and 52 dogs in 10 villages from four geographical areas in 2014. Direct Agglutination Test (DAT) was done for all samples after serum separation of blood in the leishmaniasis laboratory from the School of Public Health, Tehran University of Medical Sciences.
In all, of 872 human, 9 samples were shown anti-Leishmania antibody with titers ≥ 1/1600 and 11 samples with titers ≥ 1/800. Of 52 dog samples, 11 dog samples with titers ≥ 1/320 as cut-off values of DAT and 13 with titers 1/80 and 1/160.
None of collected human blood samples showed anti Leishmania infantum
antibodies at titers 1:320 as well as None of the dogs had clinical signs. This indicates that asymptomatic dogs also like symptomatic dogs, able to transmit infection and play an active role in the circulation of Leishmania infantum. This study confirms the circulation of L. infantum at least among dogs. We reommended that investigate vectors and wild canines as reservoir hosts of VL in the studied areas.
