CONSTRUCTION

Construction site runoff can contaminate local
rivers, ponds and creeks with sediment,
suspended solids and hydrocarbons. Turbid
brwater not only affects the aesthetics of
these bodies of water, but also disturbs the
natural habitats of aquatic wildlife.
Construction wastewater runoff is highly
regulated and offenses can result in total
project shutdown or fines in excess of $10,000.

dredging


Dredging is the process of removing excess sediment
and sludge from lakes, channels, lagoons and other
bodies of water. Dober’s Water Treatment division
offers natural chemistry and solutions for aiding
in the dewatering process.

stormwater

Polluted industrial stormwater is a major source
of environmental contamination. Runoff from
industrial sites enters storm drains and is
carried into local ponds, creeks and rivers.
Industrial contributors, such as construction
sites, often are a major source of oily waste,
suspended solids, heavy metals and hydrocarbons
pollution.

coal ash


Coal ash, or coal combustion residuals (CCRs),
the waste from coal-fired power plants,
contains contaminants like mercury, cadmium,
arsenic and chromium, which are associated
with serious health effects. Often collected
in coal ash ponds adjacent to natural waterways,
this industrial waste is subject to new EPA
regulations, along with increased pressure to
close or relocate many of the collection ponds.

Mining & Aggregate

Wastewater from mining and aggregate operations
must be properly managed to prevent any water
or soil pollution arising from leaching of
heavy metals. Mining wastewater is often
acidic, requiring that lime, limestone, or
caustic soda be added to the wastewater
to raise its pH. Dissolved metals can then
precipitate out of solution and sink to the
bottom of settling or sedimentation ponds.

wheel wash


In order to prevent potential hazards and dirty,
unsafe roadways, highway regulations mandate
that all vehicles leaving industrial sites and
entering public highways must be clean with
wheels free of debris. Failure to comply with
these regulations can lead to fines and
additional costs for cleaning the roadway. The
wheel wash process generates wastewater that is
filled with contaminates.
