“…High conductivity values were recorded in locations with high TDS values as expected. The high TDS values obtained (table 2) are similar to those reported by (Ozoemenam, 2012;Okiongbo et al, 2014;Fashola, 2013) in the Niger Delta region. It is a known fact that shallow aquifers within this area and the larger Niger Delta region serve as a domestic water supply source especially in communities where these sources are not polluted by hydrocarbons (oil spills).…”

Sand casting is the most widely used casting technique, known for ages, even since ancient times. The main goal of this study was to determine the thermal decomposition behaviour of foundry sand for cast steel. We first tested the basic properties of foundry sand, including its proximate analysis, chemical composition, and particle size characteristics; we next monitored the thermal decomposition behaviour of foundry sand for cast steel via simultaneous thermal analysis. We focused on the mass loss of foundry sand for cast steel at different heating rates in nitrogen and air atmospheres. We adopted a novel method to calculate the volatile release characteristic index of foundry sand. The volatile content of foundry sand for cast steel was very low, so the volatile release characteristic index of the sand could not be strictly calculated according to this concept. We calculated the thermal decomposition kinetics parameters of foundry sand, namely, the activation energy and preexponential factor, under kinetics theory. To thoroughly test the fitting effect, we conducted a single-factor analysis of variance on the source of error. The results showed that the independent variable has a significant influence on the dependent variable and that the fitting equation we selected is feasible and effective.

“…The report on sanitation is even worse as only 30% of Sub-Saharan Africa has access to improved sanitation facilities leaving about 70% without access [5]. As a result of the limited access to sanitation facilities, people in rural communities resort to indiscriminate open defecation which has the tendency of contaminating their surface water sources [6,7].…”

In order to assess the sanitation and water supply coverage in a rural community of Kogi State, Nigeria as a knowledge base for the actualization of the Sustainable Development Goals 6.1 and 6.2, a cross-sectional study was carried out amongst 325 household heads in Oforachi community using the quantitative method of data collection. The Field survey was carried out between October and December, 2017. All households who gave consent to participate in the study were included while those who declined consent were excluded. The results were presented using descriptive statistics (frequencies, percentages, means and standard deviations) while, student's t-test was used to assess whether the household's choice of water source is connected to the nearness of the source to them or not. This was done at 95% Confidence Level using STATA/SE 13.1 Statistical Software. The results showed that 34.77% of the households had improved sanitation facilities,
