Erec India Research Laboratory  is a NABL Accredited Laboratory and  it is the only ISO 17025: 2005 (NABL Standard) water testing laboratory in entire North East region situated at Rupnagar, Guwahati

specially for

  1. Water testing
  2. Construction material testing and
  3. Building testing.

The testing parameters of each category are as under:

  1. Water Testing:  Drinking Water Testing, Packaged Drinking Water Testing, Effluent Water, Fishery Water, Recreational Water (Swimming pool) and River Water Testing.

                   The required test parameters available are done as per BISAPHA  and method. The list of testing facilities are appended  hereunder.

  1. Engineering Laboratory: The other sector of the Laboratory is presently growing up specially for building material testing. The testing parameters are :
  • Reinforcement (Rebar) testing
  • Cube testing,
  • Brick testing, …………all are presently available.

The other facilities like –Cement testing, Aggregate testing, Rock testing etc. are going to setup within a very short period.

  1. Building testing : This section is under the banner of Environmental Research and Evaluation Centre (EREC) which is an NGO  established in 2007. These testing are carried with the help of Sophisticated imported digital ultra modern machine which are applied for the purpose of  :
  •  Determination of Compressive strength of concrete  specially for STRUCTURAL SAFETY CERTIFICATE for the building (new & old).
  •  Detection of  rebar location, position, coverage, dia., nos. of rebar etc inside the concrete.
  •  Detection of  rusting on rebar inside concrete
  •  Crack detection on concrete members

Parameters for drinking water quality typically fall under two categories: chemical/physical and microbiological. Chemical/physical parameters include heavy metals, trace organic compounds, total suspended solids (TSS), and turbidity. Microbiological parameters include Coliform bacteria, E. coli, and specific pathogenic species of bacteria(such as cholera-causing Vibrio
