Abstract
Background and Objective: Nitrite waste is an important factor in determining the
sustainability of underground water quality that can be associated with the value of
nitrite concentration based on the water quality standard. This study aims to
determine the distribution of nitrite waste in the lithology of the study area.
Materials and Methods: This study was conducted using experimental methods.
These measurements use equipment that suits the needs of pizometers, geoelectric
equipment, GPS. The data obtained are data ratio such as hydraulic conductivity
data, well depth, well position, nitrite concentration and coordinate of research
location. Contour distribution model of nitrite waste in lithology using Surfer-13
software. Results and Discussion: Nitrite concentrations obtained through existing
wells in community settlements ranged from 0.005 mg / L to 0.09 mg / L. While for
class I, II and III is 0.06 mg / L while class IV is not required. This concentration
value is actually a value derived from the accumulation of all sources of pollutants
that exist in the city of Pekanberu, therefore this research is included in the research
source of pollution spread (Nonpoint Source Polutan). Conclusion: The highest
nitrite concentration values were in Rumbai, Rumbai Pesisir, Sail and Tenayan Raya
sub-districts with an average of 0.08 mg / L, while the lowest was Marpoyan Damai
and Tampan sub-district with an average of 0.014 mg / L. Although this
concentration value ranges from 0.08 mg / L which exceeds the water quality
standard for each class of 0.06 mg / L, it is still less than 1 mg / L and is suitable for
community use.
