Stream Sampling

Streams and open water sources are exposed to contamination from surface runoff, wastewater and nearby industrial and agricultural activity. Stream water sampling monitors water quality and the state of the ecosystem, and pinpoints sources of pollution before they spread downstream. Kesar Digum collects representative samples through certified samplers, sends them for testing in an ISO 17025 accredited laboratory in line with the requirements of the Ministry of Environmental Protection, nationwide.

Monitoring Water Quality in Streams, From Source to Downstream

Streams sit at the meeting point of nature, industry and agriculture - and any flow of surface runoff, wastewater or pesticides can alter water quality and harm the ecosystem. Periodic stream water sampling checks biological, chemical and physical parameters, pinpoints sources of pollution and provides a reliable picture for authorities, plants and stream restoration bodies. Kesar Digum guides the entire process - from planning the sampling points along the stream, through collecting samples in the field with certified samplers and testing in an accredited laboratory, to a clear results report with recommendations.

Who This Service Is For

What the Service Includes

What Is Tested in Stream Sampling

Biological, chemical and physical parameters, based on the stream's characteristics and the regulator's requirements.

Biological and Microbial Testing

Fecal coliform counts, E. coli and bacterial indicators - a sign of wastewater intrusion and fecal contamination in the stream channel.

Chemical and Physical Testing

Dissolved oxygen, organic load (BOD/COD), nitrogen, phosphorus, heavy metals, turbidity, conductivity and pH - measures of water quality and the stream's health.

Tracing the Source of Pollution in a Stream

Industrial or domestic wastewater discharge into a stream is traced through targeted sampling along the flow and complementary wastewater testing.

Full Details

Planning a Stream Monitoring Program

Building a network of sampling points and frequencies along the stream, in line with the regulator's requirements and the drainage basin's characteristics.

Regulation

When Is Stream Sampling Required?

Stream monitoring is required in a range of situations, both by authorities and by bodies operating near a stream. These are the most common:

Plant or Business Near a Stream

A body that discharges runoff or effluent toward a stream must monitor its impact on water quality upstream and downstream of the discharge point.

Periodic

Stream Restoration Programs

Stream restoration and rehabilitation projects require baseline sampling before work begins and ongoing tracking of the improvement in water quality over time.

Throughout the Project

Infrastructure and Construction Work

Earthworks, bridging or pipe-laying near a stream require monitoring to prevent sludge, fuels and pollutants from flowing into the channel.

Per Event

Suspected Pollution or Unusual Event

A change in color or odor, fish die-off or a report of an unauthorized discharge requires immediate sampling to determine the source and extent of the pollution.

Per Event
The Risk

What Happens When a Stream Becomes Polluted?

Stream pollution doesn't stop at the banks of the channel - it spreads downstream, into the soil and into the groundwater. Here's what's at stake:

Harm to the Ecosystem

Organic and chemical pollution depletes the dissolved oxygen in the water and harms fish, vegetation and the stream's biodiversity.

Groundwater and Water Source Contamination

Pollutants that seep from the stream channel into the soil can reach the groundwater and nearby drinking water sources.

Polluter Liability

A body that discharges pollutants into a stream is exposed to enforcement by the Ministry of Environmental Protection, fines and lawsuits for environmental damage.

Schedule Sampling

Need to schedule stream sampling?

We'll build a monitoring plan suited to the length of the stream, carry out representative sampling in the field and deliver a report with results and recommendations for meeting the Ministry of Environmental Protection's requirements - nationwide.
